1. X86 – X86 is a family of backward-compatible instruction set architectures based on the Intel 8086 CPU and its Intel 8088 variant. The term x86 came into being because the names of several successors to Intels 8086 processor end in 86, many additions and extensions have been added to the x86 instruction set over the years, almost consistently with full backward compatibility. The architecture has been implemented in processors from Intel, Cyrix, AMD, VIA and many companies, there are also open implementations. In the 1980s and early 1990s, when the 8088 and 80286 were still in common use, today, however, x86 usually implies a binary compatibility also with the 32-bit instruction set of the 80386. An 8086 system, including such as 8087 and 8089. There were also terms iRMX, iSBC, and iSBX – all together under the heading Microsystem 80, however, this naming scheme was quite temporary, lasting for a few years during the early 1980s. Today, x86 is ubiquitous in both stationary and portable computers, and is also used in midrange computers, workstations, servers. A large amount of software, including operating systems such as DOS, Windows, Linux, BSD, Solaris and macOS, functions with x86-based hardware. There have been attempts, including by Intel itself, to end the market dominance of the inelegant x86 architecture designed directly from the first simple 8-bit microprocessors. Examples of this are the iAPX432, the Intel 960, Intel 860, however, the continuous refinement of x86 microarchitectures, circuitry and semiconductor manufacturing would make it hard to replace x86 in many segments. The table below lists processor models and model series implementing variations of the x86 instruction set, each line item is characterized by significantly improved or commercially successful processor microarchitecture designs. Such x86 implementations are seldom simple copies but often employ different internal microarchitectures as well as different solutions at the electronic, quite naturally, early compatible microprocessors were 16-bit, while 32-bit designs were developed much later. For the personal computer market, real quantities started to appear around 1990 with i386 and i486 compatible processors, other companies, which designed or manufactured x86 or x87 processors, include ITT Corporation, National Semiconductor, ULSI System Technology, and Weitek. Some early versions of these microprocessors had heat dissipation problems, AMD later managed to establish itself as a serious contender with the K6 set of processors, which gave way to the very successful Athlon and Opteron. There were also other contenders, such as Centaur Technology, Rise Technology, VIA Technologies energy efficient C3 and C7 processors, which were designed by the Centaur company, have been sold for many years. Centaurs newest design, the VIA Nano, is their first processor with superscalar and it was, perhaps interestingly, introduced at about the same time as Intels first in-order processor since the P5 Pentium, the Intel Atom. The instruction set architecture has twice been extended to a word size. In 1999-2003, AMD extended this 32-bit architecture to 64 bits and referred to it as x86-64 in early documents, Intel soon adopted AMDs architectural extensions under the name IA-32e, later using the name EM64T and finally using Intel 64
2. Programmable Array Logic – Programmable Array Logic is a family of programmable logic device semiconductors used to implement logic functions in digital circuits introduced by Monolithic Memories, Inc. in March 1978. MMI obtained a trademark on the term PAL for use in Programmable Semiconductor Logic Circuits. The trademark is held by Lattice Semiconductor. PAL devices consisted of a small PROM core and additional output logic used to implement particular desired logic functions with few components, using specialized machines, PAL devices were field-programmable. PALs were available in variants, One-time programmable devices could not be updated and reused after initial programming. UV erasable versions had a window over the chip die. Later versions were flash erasable devices, in most applications, electrically-erasable GALs are now deployed as pin-compatible direct replacements for one-time programmable PALs. One PAL device would typically replace dozens of discrete logic packages. PALs were used advantageously in many products, such as minicomputers, PALs were not the first commercial programmable logic devices, Signetics had been selling its field programmable logic array since 1975. These devices were completely unfamiliar to most circuit designers and were perceived to be too difficult to use, the FPLA had a relatively slow maximum operating speed, was expensive, and had a poor reputation for testability. Another factor limiting the acceptance of the FPLA was the large package, the project to create the PAL device was managed by John Birkner and the actual PAL circuit was designed by H. T. Chua. In a previous job, Birkner had developed a 16-bit processor using 80 standard logic devices and his experience with standard logic led him to believe that user programmable devices would be more attractive to users if the devices were designed to replace standard logic. This meant that the package sizes had to be typical of the existing devices. MMI intended PALs to be a low cost part. However, they initially had severe manufacturing yield problems and had to sell the devices for over $50 and this threatened the viability of the PAL as a commercial product and they were forced to license the product line to National Semiconductor. PALs were later second sourced by Texas Instruments and Advanced Micro Devices, early PALs were 20-pin DIP components fabricated in silicon using bipolar transistor technology with one-time programmable titanium-tungsten programming fuses. Later devices were manufactured by Cypress, Lattice Semiconductor and Advanced Micro Devices using CMOS technology, the original 20 and 24-pin PALs were denoted by MMI as medium-scale integration devices. The PAL architecture consists of two components, a logic plane and output logic macrocells
3. Advanced Micro Devices – While initially it manufactured its own processors, the company became fabless after GlobalFoundries was spun off in 2009. AMDs main products include microprocessors, motherboard chipsets, embedded processors and graphics processors for servers, workstations and personal computers, AMD is the second-largest supplier and only significant rival to Intel in the market for x86-based microprocessors. Since acquiring ATI in 2006, AMD and its competitor Nvidia have dominated the discrete Graphics Processing Unit market, Advanced Micro Devices was formally incorporated on May 1,1969, by Jerry Sanders, along with seven of his colleagues from Fairchild Semiconductor. In September 1969, AMD moved from its location in Santa Clara to Sunnyvale. To immediately secure a base, AMD initially became a second source supplier of microchips designed by Fairchild. AMD first focused on producing logic chips, in November 1969, the company manufactured its first product, the Am9300, a 4-bit MSI shift register, which began selling in 1970. Also in 1970, AMD produced its first proprietary product, the Am2501 logic counter and its best-selling product in 1971 was the Am2505, the fastest multiplier available. In 1971, AMD entered the RAM chip market, beginning with the Am3101 and that year AMD also greatly increased the sales volume of its linear integrated circuits, and by year end the companys total annual sales reached $4.6 million. AMD went public in September 1972, the company was a second source for Intel MOS/LSI circuits by 1973, with products such as Am14/1506 and Am14/1507, dual 100-bit dynamic shift registers. By 1975, AMD was producing 212 products – of which 49 were proprietary, including the Am9102, Intel had created the first microprocessor, its 4-bit 4004, in 1971. By 1975, AMD entered the market with the Am9080, a reverse-engineered clone of the Intel 8080. In 1977, AMD entered into a joint venture with Siemens, Siemens purchased 20% of AMDs stock, giving AMD an infusion of cash to increase its product lines. When the two companies vision for Advanced Micro Computers diverged, AMD bought out Siemens stake in the U. S. division in 1979, AMD closed its Advanced Micro Computers subsidiary in late 1981, after switching focus to manufacturing second-source Intel x86 microprocessors. Total sales in fiscal year 1978 topped $100 million, and in 1979, in 1980, AMD began supplying semiconductor products for telecommunications, an industry undergoing rapid expansion and innovation. Intel had introduced the first x86 microprocessors in 1978, in 1981, IBM created its PC, and wanted Intels x86 processors, but only under the condition that Intel also provide a second-source manufacturer for its patented x86 microprocessors. Intel and AMD entered into a 10-year technology exchange agreement, first signed in October 1981, the technical information and licenses needed to make and sell a part would be exchanged for a royalty to the developing company. The 1982 agreement also extended the 1976 AMD–Intel cross-licensing agreement through 1995, the agreement included the right to invoke arbitration of disagreements, and after five years the right of either party to end the agreement with one years notice. It also continued its successful concentration on proprietary bipolar chips, in 1983, it introduced INT. STD.1000, the highest manufacturing quality standard in the industry
4. Atmel – Atmel Corporation is an American-based designer and manufacturer of semiconductors, founded in 1984. The company focuses on embedded systems built around microcontrollers, Atmel supplies its devices as standard products, application-specific integrated circuits, or application-specific standard product depending on the requirements of its customers. Atmel serves applications including consumer, communications, computer networking, industrial, medical, automotive, aerospace and it specializes in microcontroller and touch systems, especially for embedded systems. Atmels corporate headquarters is in San Jose, California, Atmel makes much of its product line at vendor fabrication facilities. It owns a facility in Colorado Springs, Colorado that manufactures its XSense line of touch sensors. In 2016, Microchip agreed to buy Atmel for US$3.6 billion in a deal brokered by JPMorgan Chase, Atmel Corporation was founded in 1984, by George Perlegos. Atmel was an acronym for “advanced technology for memory and logic”, Perlegos had worked in the memory group of Intel in the 1970s and had co-founded Seeq Technology to manufacture EPROM memory. Using only US$30,000 in capital, Atmel was initially operated as a company, using Sanyo. The first Atmel memory products used less power than competitors, customers included Motorola, Nokia, and Ericsson. In 1987 Intel sued Atmel for patent infringement, rather than fight the patent claim, Atmel redesigned its products to use different intellectual property. These had better performance and even power consumption. In addition, Atmel then entered the flash memory business that Intel had focused on, Atmel used US$60 million in venture capital for the 1989 purchase of a fabrication facility from Honeywell in Colorado Springs. Atmel then invested another US$30 million in manufacturing technology, in 1991, Atmel expanded the Colorado facility after acquiring Concurrent Logic, a field-programmable gate array manufacturer. The company made its public offering in 1991 which yielded more than US$65 million. 1994 saw Atmel enter the microprocessor market, the first Atmel flash memory microcontroller was based on the Intel 8051. The controller executed an instruction for every cycle, as opposed to the 12 cycles that legacy 8051 parts required. In 1994, Atmel purchased the EEROM assets of Seeq Technology, Atmel now has dozens of families of ARM-based devices. In 1995, Atmel opened a facility in Rousset, France
5. Intel – Intel Corporation is an American multinational corporation and technology company headquartered in Santa Clara, California that was founded by Gordon Moore and Robert Noyce. It is the worlds largest and highest valued semiconductor chip makers based on revenue, and is the inventor of the x86 series of microprocessors, Intel supplies processors for computer system manufacturers such as Apple, Lenovo, HP, and Dell. Intel Corporation was founded on July 18,1968, by semiconductor pioneers Robert Noyce and Gordon Moore, the companys name was conceived as portmanteau of the words integrated and electronics. The fact that intel is the term for intelligence information made the name appropriate. Intel was a developer of SRAM and DRAM memory chips. Although Intel created the worlds first commercial microprocessor chip in 1971, during the 1990s, Intel invested heavily in new microprocessor designs fostering the rapid growth of the computer industry. The Open Source Technology Center at Intel hosts PowerTOP and LatencyTOP, and supports other projects such as Wayland, Intel Array Building Blocks, and Threading Building Blocks. Client Computing Group – 55% of 2016 revenues – produces hardware components used in desktop, data Center Group – 29% of 2016 revenues – produces hardware components used in server, network, and storage platforms. Internet of Things Group – 5% of 2016 revenues – offers platforms designed for retail, transportation, industrial, buildings, non-Volatile Memory Solutions Group – 4% of 2016 revenues – manufactures NAND flash memory products primarily used in solid-state drives. Intel Security Group – 4% of 2016 revenues – produces software, particularly security, programmable Solutions Group – 3% of 2016 revenues – manufactures programmable semiconductors. In 2016, Dell accounted for 15% of Intels total revenues, Lenovo accounted for 13% of total revenues, in the 1980s, Intel was among the top ten sellers of semiconductors in the world. In 1991, Intel became the biggest chip maker by revenue and has held the position ever since, other top semiconductor companies include TSMC, Advanced Micro Devices, Samsung, Texas Instruments, Toshiba and STMicroelectronics. Competitors in PC chip sets include Advanced Micro Devices, VIA Technologies, Silicon Integrated Systems, however, the cross-licensing agreement is canceled in the event of an AMD bankruptcy or takeover. Some smaller competitors such as VIA Technologies produce low-power x86 processors for small factor computers, however, the advent of such mobile computing devices, in particular, smartphones, has in recent years led to a decline in PC sales. Since over 95% of the worlds smartphones currently use processors designed by ARM Holdings, ARM is also planning to make inroads into the PC and server market. Intel has been involved in disputes regarding violation of antitrust laws. Intel was founded in Mountain View, California in 1968 by Gordon E. Moore, a chemist, and Robert Noyce, arthur Rock helped them find investors, while Max Palevsky was on the board from an early stage. Moore and Noyce had left Fairchild Semiconductor to found Intel, Rock was not an employee, but he was an investor and was chairman of the board
6. National Semiconductor – National Semiconductor was an American semiconductor manufacturer which specialized in analog devices and subsystems, formerly with headquarters in Santa Clara, California, United States. The company produced power management integrated circuits, display drivers, audio and operational amplifiers, communication interface products, Nationals key markets included wireless handsets, displays and a variety of broad electronics markets, including medical, automotive, industrial and test and measurement applications. On September 23,2011, the company became part of Texas Instruments as the Silicon Valley division. The founding of the new company was followed by Sperry Rand filing a lawsuit against National Semiconductor for patent infringement, by 1965, as it was reaching the courts, the preliminaries of the lawsuit had caused the stock value of National to be depressed. The depressed stock values allowed Peter J Sprague to invest heavily in the company with Spragues family funds, Sprague also relied on further financial backing from a pair of west coast investment firms and a New York underwriter to take control as the Chairman of National Semiconductor. At that time Sprague was 27 years old, young characterised the era as the beginning of venture capitalism. That same year National Semiconductor acquired Molectro, Molectro was founded in 1962, in Santa Clara, California by J. Nall and D. Spittlehouse, who were formerly employed at Fairchild Camera and Instrument Corporation. The acquisition also brought to National Semiconductor two experts in linear semiconductor technologies, Robert Widlar and Dave Talbert, who were formerly employed at Fairchild. The acquisition of Molectro provided National with the technology to itself in the fabrication. In 1967, Sprague hired five top executives away from Fairchild, among whom were Charles E. Sporck, at the time of Sporcks hiring, Robert Noyce was de facto head of semiconductor operations at Fairchild and Sporck was his operations manager. Sporck was appointed President and CEO of National, to make the deal better for Sporcks hiring and appointment for half his former salary at Fairchild, Sporck was allotted a substantial share of Nationals stock. In essence, Sporck took four of his personnel from Fairchild with him as well as three others from TI, Perkin-Elmer and Hewlett Packard to form a new eight man team at National Semiconductor. Incidentally, Sporck had been Widlars superior at Fairchild before Widlar left Fairchild to join Molectro due to a dispute with Sporck. In 1968, National shifted its headquarters from Danbury, Connecticut to Santa Clara, however, like many companies, National retained its registration as a Delaware corporation, for legal and financial expediency. Over the years National Semiconductor acquired several companies like Fairchild Semiconductor, however, over time National Semiconductor spun off these acquisitions. Fairchild Semiconductor became a company again in 1997 and the Cyrix microprocessors division was sold to VIA Technologies of Taiwan in 1999. Based largely on the success of the WebPad National formed the Information Appliance division in 1998, the Information Appliance Division was sold to AMD in 2003. Immediately after becoming CEO, Sporck started a price war among semiconductor companies
7. Xilinx – Xilinx, Inc. is an American technology company, primarily a supplier of programmable logic devices. It is known for inventing the field-programmable gate array and as the first semiconductor company with a fabless manufacturing model, major FPGA product families include Virtex, Kintex and Artix, and the retired Spartan series. Major computer software includes Xilinx ISE and Vivado Design Suite, Ross Freeman, Bernard Vonderschmitt, and James V Barnett II, who all had worked for integrated circuit and solid-state device manufacturer Zilog Corp, founded Xilinx in 1984. While working for Zilog, Freeman wanted to create chips that acted like a blank tape, at the time, the concept was paradigm changing. Big semiconductor manufacturers were enjoying strong profits by producing massive volumes of generic circuits, designing and manufacturing dozens of different circuits for specific markets offered lower profit margins and required greater manufacturing complexity. What became known as the FPGA would allow circuits produced in quantity to be tailored by individual market segments, Freeman failed to convince Zilog to invest in creating the FPGA to chase what was only a $100 million market at the time. Freeman and Barnett left Zilog and teamed up with their 60-year-old ex-colleague Bernard Vonderschmitt to raise $4.5 million in funding to design the first commercially viable FPGA. They incorporated the company in 1984 and began selling its first product by 1985, by late 1987 the company had raised more than $18 million in venture capital and generated revenues at an annualized rate of nearly $14 million. As demand for programmable logic continued to grow, so did Xilinxs revenues, from 1988 to 1990, the companys revenue grew each year from $30 million to $50 million to $100 million. During this time period, the company which had been providing funding to Xilinx, as a result, Xilinx dissolved the deal with MMI and went public on the NASDAQ in 1989. The company also moved to a 144, 000-square-foot plant in San Jose, California in order to pace with demand from companies like HP. IBM and Sun Microsystems who were buying large quantities from Xilinx, Xilinx competitors emerged in the FPGA market in the mid-1990s. Despite the competition, Xilinxs sales grew to $135 million in 1991, $178 million in 1992, the company reached $550 million in revenue in 1995, one decade after having sold its first product. According to market research firm iSuppli, Xilinx has held the lead in programmable logic device market share since the late 1990s, over the years, Xilinx expanded operations to India, Asia and Europe. Xilinxs sales rose from $560 million in 1996 to $2.2 billion by the end of its fiscal year 2013 and these targeted design platforms are an alternative to costly application-specific integrated circuits and application-specific standard products. The company has expanded its product portfolio since its founding, Xilinx sells a broad range of FPGAs, complex programmable logic devices, design tools, intellectual property and reference designs. Xilinx also has a services and training program. The companys products have been recognized by EE Times, EDN and others for innovation, in addition to Zynq-7000, Xilinx product lines include the Virtex, Kintex and Artix series, each including configurations and models optimized for different applications
8. Field-programmable gate array – A field-programmable gate array is an integrated circuit designed to be configured by a customer or a designer after manufacturing – hence field-programmable. The FPGA configuration is generally specified using a description language. Logic blocks can be configured to perform complex functions, or merely simple logic gates like AND. In most FPGAs, logic blocks also include elements, which may be simple flip-flops or more complete blocks of memory. Contemporary field-programmable gate arrays have large resources of logic gates and RAM blocks to implement complex digital computations, as FPGA designs employ very fast I/Os and bidirectional data buses, it becomes a challenge to verify correct timing of valid data within setup time and hold time. Floor planning enables resources allocation within FPGAs to meet time constraints. FPGAs can be used to implement any logical function that an ASIC could perform, some FPGAs have analog features in addition to digital functions. Fairly common are differential comparators on input pins designed to be connected to differential signaling channels, the FPGA industry sprouted from programmable read-only memory and programmable logic devices. PROMs and PLDs both had the option of being programmed in batches in a factory or in the field, however, programmable logic was hard-wired between logic gates. In the late 1980s, the Naval Surface Warfare Center funded an experiment proposed by Steve Casselman to develop a computer that would implement 600,000 reprogrammable gates, Casselman was successful and a patent related to the system was issued in 1992. Some of the foundational concepts and technologies for programmable logic arrays, gates. Xilinx co-founders Ross Freeman and Bernard Vonderschmitt invented the first commercially viable field-programmable gate array in 1985 – the XC2064, the XC2064 had programmable gates and programmable interconnects between gates, the beginnings of a new technology and market. The XC2064 had 64 configurable logic blocks, with two three-input lookup tables, more than 20 years later, Freeman was entered into the National Inventors Hall of Fame for his invention. Altera and Xilinx continued unchallenged and quickly grew from 1985 to the mid-1990s, by 1993, Actel was serving about 18 percent of the market. By 2010, Altera, Actel and Xilinx together represented approximately 77 percent of the FPGA market, the 1990s were an explosive period of time for FPGAs, both in sophistication and the volume of production. In the early 1990s, FPGAs were primarily used in telecommunications, by the end of the decade, FPGAs found their way into consumer, automotive, and industrial applications. This work mirrors the architecture by Ron Perlof and Hana Potash of Burroughs Advanced Systems Group which combined a reconfigurable CPU architecture on a chip called the SB24. That work was done in 1982, the Atmel FPSLIC is another such device, which uses an AVR processor in combination with Atmels programmable logic architecture
9. PSoC – PSoC is a family of microcontroller integrated circuits by Cypress Semiconductor. These chips include a CPU core and mixed-signal arrays of configurable integrated analog, in 2002, Cypress began shipping commercial quantities of the PSoC1. To promote the PSoC, Cypress sponsored a PSoC Design Challenge in Circuit Cellar magazine in 2002 and 2004, in April 2013, Cypress released the fourth generation, PSoC4. PSoC is used in devices as simple as Sonicare toothbrushes and Adidas sneakers, one PSoC, using CapSense, controls the touch-sensitive scroll wheel on the Apple iPod click wheel. In 2014, Cypress extended the PSoC4 family by integrating a Bluetooth Low Energy radio along with a PSoC4 Cortex-M0-based SoC in a single, in 2016, Cypress released PSoC4 S-Series, featuring ARM Cortex-M0+ CPU. A PSoC integrated circuit is composed of a core, configurable analog and digital blocks, the configurable blocks in a PSoC are the biggest difference from other microcontrollers. PSoC has three separate spaces, paged SRAM for data, Flash memory for instructions and fixed data. The device is created using SONOS technology, PSoC resembles an ASIC, blocks can be assigned a wide range of functions and interconnected on-chip. Unlike an ASIC, there is no special manufacturing process required to create the custom configuration — only startup code that is created by Cypress PSoC Designer or PSoC Creator IDE. PSoC resembles an FPGA in that at power up it must be configured, PSoC most closely resembles a microcontroller combined with a PLD and programmable analog. Code is executed to interact with the peripheral functions, using automatically generated APIs. PSoC Designer or PSoC Creator generate the startup configuration code, both integrate APIs that initialize the user selected components upon the users needs in a Visual-Studio-like GUI. Using configurable analog and digital blocks, designers can create and change mixed-signal embedded applications, the digital blocks are state machines that are configured using the blocks registers. There are two types of blocks, Digital Building Blocks and Digital Communication Blocks. Only the communication blocks can contain serial I/O user modules, such as SPI, UART, concatenating UMs together is how 16-bit PWMs and timers are created. There are two types of analog blocks, the continuous time blocks are composed of an op-amp circuit and designated as ACBxx where xx is 00-03. The other type is the switch cap blocks, which allow complex analog signal flows and are designated by ASCxy where x is the row, designers can modify and personalize each module to any design. PSoC mixed-signal arrays flexible routing allows designers to route signals to, global buses allow for signal multiplexing and for performing logic operations
