PlayStation 3 technical specifications
The PlayStation 3 technical specifications describe the various components of the PlayStation 3 video game console. The PS3 uses the Cell microprocessor, made up of one 3.2 GHz PowerPC-based "Power Processing Element" and six accessible Synergistic Processing Elements. A seventh runs in a special mode and is dedicated to aspects of the OS and security, an eighth is a spare to improve production yields. PlayStation 3's Cell CPU achieves a theoretical maximum of 230.4 GFLOPS in single precision floating point operations and up to 15 GFLOPS double precisionThe PS3 has 256 MB of Rambus XDR DRAM, clocked at CPU die speed. The PPE has 64 KB L1 cache and 512 KB L2 cache, while the SPEs have 2 MB local memory, connected by the Element Interconnect Bus with up to 307.2 GB/s bandwidth. According to Nvidia, the RSX—the graphics processing unit —is based on the NVIDIA G70 architecture; the GPU is clocked at 500 MHz and makes use of 256 MB GDDR3 RAM clocked at 650 MHz with an effective transmission rate of 1.3 GHz.
The RSX has a floating-point performance of 192 GFLOPS. To date, the PS3 has had several component revisions; this in turn results in production savings, lower heat production, lower cooling requirements and quieter running. Since launch, the Cell processor has shrunk from 90 nm to 45 nm; the RSX GPU has seen reduction in size over periodic revisions of the PS3. Major improvements were introduced with the PS3 Slim, it utilized a 45 nm Cell which resulted in a 34% reduction in power consumption over the previous 65 nm Cell model. On all models of the PS3, the last seven characters of the serial number make up the console's model number; this begins with "CECH", followed by a letter indicating. The last two characters of the model number indicate. In terms of audio, the PS3 supports a number of formats, including 7.1 digital audio, Dolby TrueHD, DTS-HD Master Audio and others. The PS3 slim features an upgraded HDMI chip that allows bitstreaming of lossless audio codecs to an external receiver.. In the early 60 GB and 80 GB configurations, flash memory can be used, either Memory Sticks.
All models support USB memory devices. However, they must be formatted with the FAT32 file system. Earlier systems sported up to four USB 2.0 ports at the front, but the 40 GB and 80 GB PAL models only have two USB ports. All models released after August 2008 have been reduced to two USB ports at the front, as well as dropping CompactFlash and SD card support. For networking, all models provide one Gigabit Ethernet RJ45 port. Bluetooth 2.0 support, built-in 802.11b/g Wi-Fi. The original PlayStation 3's case was designed by Teiyu Goto of Sony, uses the Spider-Man 3 font, it has a glossy piano-black finish, the power and eject buttons are touch-sensitive. The PlayStation 3 Slim is more compact than its predecessor; the engraved logo is an update of the PS2's with curved edges. The PlayStation 3 Super Slim weighs at least 25% less than the Slim due in part to the slot-loading Blu-ray drive being replaced with a top-load disc reader similar to the original PlayStation's, but with a sliding cover; the power consumption of the initial PlayStation 3 units, based on 90 nm Cell CPU, ranges from 170–200 W during normal use, despite having a 380 W power supply.
The power consumption of newer 40 GB PlayStation 3 units, ranges from 120-140 W during normal use. The power consumption of "slim" PlayStation 3 ranges from 65-84 W during normal use; the power supply can operate on 50 Hz power grids. It uses a standard IEC 60320 C14 connector and a C13 power cord appropriate for the region it is being used in; the power supply on the "fat" model is 380 W. This was reduced to 250 W in the 120 GB "Slim" model. PS3 Slim models have labels indicating localized input requirements for power, however teardowns have revealed the slim power supplies are still universal; the PlayStation 3 disc drive is an all-in-one type allowing the use of different formats. Blu-ray disc read speed maximum is 2x, region coded type allowing the use of: PlayStation 3 BD-ROM BD-ROM BD-R BD-RE DVD disc read speed maximum is 8×, region coded type allowing the use of: PlayStation 2 DVD-ROM DVD-ROM DVD-Video DVD-Audio DVD+R DVD+RW DVD-R DVD-RW AVCHD DSD Disc DualDisc Super Audio CD Compact disc read speed maximum is 24×, region coded type allowing the use of: PlayStation 2 CD-ROM PlayStation CD-ROM CD-ROM CD-R CD-RW CD-DA MP3 CD The PlayStation 3 Sixaxis is a controller, similar in appearance to th
The PlayStation 3 is a home video game console developed by Sony Computer Entertainment. It is the successor to PlayStation 2, is part of the PlayStation brand of consoles, it was first released on November 11, 2006, in Japan, November 17, 2006, in North America, March 23, 2007, in Europe and Australia. The PlayStation 3 competed against consoles such as Microsoft's Xbox 360 and Nintendo's Wii as part of the seventh generation of video game consoles; the console was first announced at E3 2005, was released at the end of 2006. It was the first console to use Blu-ray Disc as its primary storage medium; the console was the first PlayStation to integrate social gaming services, including the PlayStation Network, as well as the first to be controllable from a handheld console, through its remote connectivity with PlayStation Portable and PlayStation Vita. In September 2009, the Slim model of the PlayStation 3 was released, it no longer provided the hardware ability to run PS2 games. It was lighter and thinner than the original version, featured a redesigned logo and marketing design, as well as a minor start-up change in software.
A Super Slim variation was released in late 2012, further refining and redesigning the console. During its early years, the system had a critically negative reception, due to its high price, a complex processor architecture and a lack of quality games, but was praised for its Blu-ray capabilities and "untapped potential"; the reception would get more positive over time. The system had a slow start in the market but managed to recover after the introduction of the Slim model, its successor, the PlayStation 4, was released in November 2013. On September 29, 2015, Sony confirmed that sales of the PlayStation 3 were to be discontinued in New Zealand, but the system remained in production in other markets. Shipments of new units to Europe and Australia ended in March 2016, followed by North America which ended in October 2016. Heading into 2017, Japan was the last territory where new units were still being produced until May 29, 2017, when Sony confirmed the PlayStation 3 was discontinued in Japan.
The PlayStation 3 began development in 2001 when Ken Kutaragi the President of Sony Computer Entertainment, announced that Sony, IBM would collaborate on developing the Cell microprocessor. At the time, Shuhei Yoshida led a group of programmers within this hardware team to explore next-generation game creation. By early 2005, focus within Sony shifted towards developing PS3 launch titles. Sony unveiled PlayStation 3 to the public on May 16, 2005, at E3 2005, along with a boomerang-shaped prototype design of the Sixaxis controller. A functional version of the system was not present there, nor at the Tokyo Game Show in September 2005, although demonstrations were held at both events on software development kits and comparable personal computer hardware. Video footage based on the predicted PlayStation 3 specifications was shown; the initial prototype shown in May 2005 featured two HDMI ports, three Ethernet ports and six USB ports. Two hardware configurations were announced for the console: a 20 GB model and a 60 GB model, priced at US$499 and US$599, respectively.
The 60 GB model was to be the only configuration to feature an HDMI port, Wi-Fi internet, flash card readers and a chrome trim with the logo in silver. Both models were announced for a simultaneous worldwide release: November 11, 2006, for Japan and November 17, 2006, for North America and Europe. On September 6, 2006, Sony announced that PAL region PlayStation 3 launch would be delayed until March 2007, because of a shortage of materials used in the Blu-ray drive. At the Tokyo Game Show on September 22, 2006, Sony announced that it would include an HDMI port on the 20 GB system, but a chrome trim, flash card readers, silver logo and Wi-Fi would not be included; the launch price of the Japanese 20 GB model was reduced by over 20%, the 60 GB model was announced for an open pricing scheme in Japan. During the event, Sony showed 27 playable PS3 games running on final hardware. PlayStation 3 was first released in Japan on November 11, 2006, at 07:00. According to Media Create, 81,639 PS3 systems were sold within 24 hours of its introduction in Japan.
Soon after its release in Japan, PS3 was released in North America on November 17, 2006. Reports of violence surrounded the release of PS3. A customer was shot, campers were robbed at gunpoint, customers were shot in a drive-by shooting with BB guns, 60 campers fought over 10 systems; the console was planned for a global release through November, but at the start of September the release in Europe and the rest of the world was delayed until March. With it being a somewhat last-minute delay, some companies had taken deposits for pre-orders, at which Sony informed customers that they were eligible for full refunds or could continue the pre-order. On January 24, 2007, Sony announced that PlayStation 3 would go on sale on March 23, 2007, in Europe, the Middle East and New Zealand; the system sold about 600,000 units in its first two days. On March 7, 2007, the 60 GB PlayStation 3 launched in Singapore with a price of S$799; the console was launched in South Korea on June 16, 2007, as a single version equipped with an 80 GB hard drive and IPTV.
Following speculation that Sony was working on a'slim' model, Sony announced the PS3 CECH-2000 model on August 18, 2009, at the Sony Gamescom press conference
Sony Interactive Entertainment
Sony Interactive Entertainment LLC is a multinational video game and digital entertainment company, a wholly owned subsidiary of Sony Corporation of America, the central hub for the American businesses under the Japanese conglomerate Sony Corporation. The company was founded in Tokyo and established on November 16, 1993, as Sony Computer Entertainment, to handle Sony's venture into video game development through its PlayStation brand. Since the successful launch of the original PlayStation console in 1994, the company has been developing the PlayStation lineup of home video game consoles and accessories. Expanding into North America and other countries, the company became Sony's main resource for research and development in video games and interactive entertainment. In April 2016, SCE and Sony Network Entertainment International was restructured and reorganized into Sony Interactive Entertainment, carrying over the operations and primary objectives from both companies; the same year, SIE moved its headquarters from Tokyo to California.
Sony Interactive Entertainment handles the research and development and sales of both hardware and software for the PlayStation video game systems. SIE is a developer and publisher of video game titles, operates several subsidiaries in Sony's largest markets: North America and Asia. By August 2018, the company had sold more than 525 million PlayStation consoles worldwide. Sony Computer Entertainment, Inc. was jointly established by Sony and its subsidiary Sony Music Entertainment Japan in 1993 to handle the company's ventures into the video game industry. The original PlayStation console was released on December 1994, in Japan; the company's North American operations, Sony Computer Entertainment of America, were established in May 1995 as a division of Sony Electronic Publishing. Located in Foster City, the North American office was headed by Steve Race. In the months prior to the release of the PlayStation in Western markets, the operations were restructured: All video game marketing from Sony Imagesoft was folded into SCEA in July 1995, with most affected employees transferred from Santa Monica to Foster City.
On August 7, 1995, Race unexpectedly resigned and was named CEO of Spectrum HoloByte three days later. He was replaced by Sony Electronics veteran Martin Homlish; this proved to be the beginning of a run of exceptional managerial turnover, with SCEA going through four presidents in a single year. The PS console was released in the United States on September 9, 1995; as part of a worldwide restructuring at the beginning of 1997, SCEA and Sony Computer Entertainment Europe were both re-established as wholly owned subsidiaries of SCEI. The launch of the second PS console, the PlayStation 2 was released in Japan on March 4, 2000, the U. S. on October 26, 2000. On July 1, 2002, chairman of SCEI, Shigeo Maruyama, was replaced by Tamotsu Iba as chairman. Jack Tretton and Phil Harrison were promoted to senior vice presidents of SCE; the PlayStation Portable was SCEI's first foray into the small handheld console market. Its development was first announced during SCE's E3 conference in 2003, it was unveiled during their E3 conference on May 11, 2004.
The system was released in Japan on December 12, 2004, in North America on March 24, 2005, in Europe and Australia on September 1, 2005. On September 14, 2005, SCEI formed Sony Computer Entertainment Worldwide Studios, a single internal entity to oversee all wholly owned development studios within SCEI, it became responsible for the creative and strategic direction of development and production of all computer entertainment software by all SCEI-owned studios—all software is produced for the PS family of consoles. Shuhei Yoshida was named as President of SCE WWS on May 16, 2008, replacing Kazuo Hirai, serving interim after Harrison left the company in early 2008. On December 8, 2005, video game developer Guerrilla Games, developers of the Killzone series, was acquired by Sony Computer Entertainment as part of its SCE WWS. On January 24, 2006, video game developer Zipper Interactive, developers of the Socom series, was acquired by Sony Computer Entertainment as part of its SCE WWS. In March 2006, Sony announced the online network for its forthcoming PlayStation 3 system at the 2006 PlayStation Business Briefing meeting in Tokyo, tentatively named "PlayStation Network Platform" and called just PlayStation Network.
Sony stated that the service would always be connected and include multiplayer support. The launch date for the PS3 was announced by Hirai at the pre-Electronic Entertainment Expo conference held at the Sony Pictures Studios in Los Angeles, California, on May 8, 2006; the PS3 was released in Japan on November 11, 2006, the U. S. date was November 17, 2006. The PSN was launched in November 2006. On November 30, 2006, president of SCEI, Ken Kutaragi, was appointed as chairman of SCEI, while Hirai president of SCEA, was promoted to president of SCEI. On April 26, 2007, Ken Kutaragi resigned from his position as chairman of SCEI and group CEO, passing on his duties to the appointed president of SCE, Hirai. On September 20, 2007, video game developers Evolution Studios and Bigbig Studios, creators of the MotorStorm series, were acquired by Sony Computer Entertainment as part of its SCE WWS. On April 15, 2009, David Reeves, president and CEO of SCE Europe, announced his forthcoming resignation from his post.
He had joined the company in 1995 and was appointed as chairman of SCEE in 2003, president in 2005. His role of president and CEO of SCEE would be taken over by Andrew House, who joined Sony Corporation in 1990; the PSP Go was released on October 1
PlayStation Portable system software
The PlayStation Portable system software is the official firmware for the PlayStation Portable. It uses the XrossMediaBar as its user interface, similar to the PlayStation 3 console. Updates add new functionality as well as security patches to prevent homebrew applications and plugins from being executed on the system. Updates can be obtained in four ways: Direct download to the PSP over Wi-Fi; this can be performed by choosing, from the XMB. Download to a PC transfer to the PSP via a USB cable or Memory Stick. Included on the UMD of some games; these games may not run with earlier firmware than the version on their UMD. See List of PlayStation Portable system software compatibilities. Download from a PS3 to a PSP system via USB cable. While system software updates can be used with consoles from any region, Sony recommends only downloading system software updates released for the region corresponding to the system's place of purchase. System software updates have added various features including a web browser, Adobe Flash Player 6 support, additional codecs for images and video, PlayStation 3 connectivity, as well as patches against several security exploits and execution of homebrew programs.
The battery must be at least 50% charged or else the system will prevent the update from installing. If the power supply is lost while writing to the system software, the console will no longer be able to operate unless the system is booted in service mode or sent to Sony for repair if still under warranty; the current version of the software, 6.61, was made available on January 15, 2015. It is a minor update released more than three years after the release of the previous version 6.60 in 2011. The PlayStation Portable uses the XrossMediaBar as its graphical user interface, used in the PlayStation 3 console, a variety of Sony BRAVIA HDTVs, Blu-ray disc players and many more Sony products. XMB displays icons horizontally across the screen. Users can navigate through them using the left and right buttons of the D-pad, which move the icons forward or back across the screen, highlighting just one at a time, as opposed to using any kind of pointer to select an option; when one category is selected, there are more specific options available to select that are spread vertically above and below the selected icon.
The version 2.50 upgrade added Unicode character encoding and Auto-Select as options in the browser's encoding menu, introduced the saving of input history for online forms. Version 2.70 of the PSP's system software introduced basic Flash capabilities to the browser. However, the player runs Flash version 6, five iterations behind the current desktop version 11, making some websites difficult to view. There are three different rendering modes: "Normal", "Just-Fit", "Smart-Fit". "Normal" will display the page with no changes, "Just-Fit" will attempt to shrink some elements to make the whole page fit on the screen and preserve layout and "Smart-Fit" will display content in the order it appears in the HTML, with no size adjustments. The browser has limited tabbed browsing, with a maximum of three tabs; when a website tries to open a link in a new window, the browser opens it in a new tab. Parents can limit content by enabling Browser Start Up Control which blocks all access to the web browser and creating a 4-digit PIN under in.
Additionally, the browser can be configured to run under a proxy server and can be protected by the security PIN to enable the use of web filtering or monitoring software through a network. TrendMicro for PSP was added as a feature that can be enabled via a subscription to filter or monitor content on the PSP; the PSP browser is slower compared to modern browsers and runs out of memory due to limitations put in place by Sony. Alternatively, Homebrew has allowed a custom version of the browser to be released that utilizes all 32/64 MB of the PSP's RAM, which allows the browser to load pages faster and have more memory for larger pages. Opera Mini can be used on PSP through PSPKVM, a homebrew application, a Sun Java Virtual Machine, it was claimed to provide much faster loading times than the default browser and provides better web page compatibility. Like many other video game consoles, the PlayStation Portable is capable of photo and video playback in a variety of formats. However, unlike Sony's home consoles such as the PlayStation 3 and the PlayStation 4, it is not possible to play Blu-ray or DVD movies
An operating system is system software that manages computer hardware and software resources and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may include accounting software for cost allocation of processor time, mass storage and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is executed directly by the hardware and makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer – from cellular phones and video game consoles to web servers and supercomputers; the dominant desktop operating system is Microsoft Windows with a market share of around 82.74%. MacOS by Apple Inc. is in second place, the varieties of Linux are collectively in third place. In the mobile sector, use in 2017 is up to 70% of Google's Android and according to third quarter 2016 data, Android on smartphones is dominant with 87.5 percent and a growth rate 10.3 percent per year, followed by Apple's iOS with 12.1 percent and a per year decrease in market share of 5.2 percent, while other operating systems amount to just 0.3 percent.
Linux distributions are dominant in supercomputing sectors. Other specialized classes of operating systems, such as embedded and real-time systems, exist for many applications. A single-tasking system can only run one program at a time, while a multi-tasking operating system allows more than one program to be running in concurrency; this is achieved by time-sharing, where the available processor time is divided between multiple processes. These processes are each interrupted in time slices by a task-scheduling subsystem of the operating system. Multi-tasking may be characterized in co-operative types. In preemptive multitasking, the operating system slices the CPU time and dedicates a slot to each of the programs. Unix-like operating systems, such as Solaris and Linux—as well as non-Unix-like, such as AmigaOS—support preemptive multitasking. Cooperative multitasking is achieved by relying on each process to provide time to the other processes in a defined manner. 16-bit versions of Microsoft Windows used cooperative multi-tasking.
32-bit versions of both Windows NT and Win9x, used preemptive multi-tasking. Single-user operating systems have no facilities to distinguish users, but may allow multiple programs to run in tandem. A multi-user operating system extends the basic concept of multi-tasking with facilities that identify processes and resources, such as disk space, belonging to multiple users, the system permits multiple users to interact with the system at the same time. Time-sharing operating systems schedule tasks for efficient use of the system and may include accounting software for cost allocation of processor time, mass storage and other resources to multiple users. A distributed operating system manages a group of distinct computers and makes them appear to be a single computer; the development of networked computers that could be linked and communicate with each other gave rise to distributed computing. Distributed computations are carried out on more than one machine; when computers in a group work in cooperation, they form a distributed system.
In an OS, distributed and cloud computing context, templating refers to creating a single virtual machine image as a guest operating system saving it as a tool for multiple running virtual machines. The technique is used both in virtualization and cloud computing management, is common in large server warehouses. Embedded operating systems are designed to be used in embedded computer systems, they are designed to operate on small machines like PDAs with less autonomy. They are able to operate with a limited number of resources, they are compact and efficient by design. Windows CE and Minix 3 are some examples of embedded operating systems. A real-time operating system is an operating system that guarantees to process events or data by a specific moment in time. A real-time operating system may be single- or multi-tasking, but when multitasking, it uses specialized scheduling algorithms so that a deterministic nature of behavior is achieved. An event-driven system switches between tasks based on their priorities or external events while time-sharing operating systems switch tasks based on clock interrupts.
A library operating system is one in which the services that a typical operating system provides, such as networking, are provided in the form of libraries and composed with the application and configuration code to construct a unikernel: a specialized, single address space, machine image that can be deployed to cloud or embedded environments. Early computers were built to perform a series of single tasks, like a calculator. Basic operating system features were developed in the 1950s, such as resident monitor functions that could automatically run different programs in succession to speed up processing. Operating systems did not exist in their more complex forms until the early 1960s. Hardware features were added, that enabled use of runtime libraries and parallel processing; when personal computers became popular in the 1980s, operating systems were made for them similar in concept to those used on larger computers. In the 1940s, the earliest electronic digital systems had no operating systems.
Electronic systems of this time were programmed on rows of mechanical switches or by jumper wires on plug boards. These were special-purpose systems that, for example, generated ballistics tables for the military or controlled the pri
PlayStation 2 technical specifications
The PlayStation 2 technical specifications describe the various components of the PlayStation 2 video game console. The sixth-generation hardware of the PlayStation 2 video game console consists of various components. At the heart of the console's configuration is its central processing unit, a custom RISC processor known as the Emotion Engine which operates at 294 MHz; the CPU relies on its integration with two vector processing units, known as VPU0 and VPU1, the Graphics Synthesizer, a floating-point unit in order to render 3D graphics. Other components, such as the system's DVD-ROM optical drive and DualShock 2 controller, provide the software and user control input. PlayStation 2 software is distributed on CD-ROM and DVD-ROM. In addition, the console can play audio CDs and DVD movies, is backwards compatible with original PlayStation games; this is accomplished through the inclusion of the original PlayStation's CPU which serves as the PS2's I/O processor. The PS2 supports limited functionality with the original PlayStation memory cards and controllers.
The PS2's DualShock 2 controller is an upgraded version of the PlayStation's DualShock with analog face, shoulder and D-pad buttons replacing the digital buttons of the original. Like its predecessor, the DualShock 2 controller features force feedback technology; the standard PlayStation 2 memory card uses Sony's MagicGate encryption. This requirement prevented the production of memory cards by third parties who did not purchase a MagicGate license. Memory cards without encryption can be used to store PlayStation game saves, but PlayStation games would be unable to read from or write to the card – such a card could only be used as a backup. There are a variety of non-Sony manufactured memory cards available for the PlayStation 2, allowing for a larger memory capacity than the standard 8 MB; however their use is unsupported and compatibility is not guaranteed. These memory cards can have up to 128 MB storage space; the console features USB and IEEE 1394 expansion ports. Compatibility with USB and IEEE 1394 devices is dependent on the software supporting the device.
For example, the PS2 BIOS will not boot an ISO image from a USB flash drive or operate a USB printer, as the machine's operating system does not include this functionality. By contrast, Gran Turismo 4 and Tourist Trophy are programmed to save screenshots to a USB mass storage device and print images on certain USB printers. A PlayStation 2 HDD can be installed via the expansion bay in the back of the console, was required to play certain games, notably the popular Final Fantasy XI.
