A CPU cache is a hardware cache used by the central processing unit of a computer to reduce the average cost to access data from the main memory. A cache is a smaller, faster memory, located closer to
Motherboard of a NeXTcube computer (1990). At the lower edge of the image left from the middle, there is the CPU Motorola 68040 operated at 25 MHz with two separate level 1 caches of 4 KiB each on the chip, one for the instructions and one for data. The board has no external L2 cache.
