WebbA processor cache is a small amount of memory on or near the processor itself that is used to speed up access to data. Since accesses to RAM are significantly slower than actual data processing, keeping the most recently and frequently used data near or on the processor can significantly increase performance. While main memory (RAM) can be … A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations. Most CPUs have a hierarchy of multiple cache levels (L1, L2, often L3, and rarely even L4), with different instruction-specific and data-specific caches at level 1. Th…

WebbCache coherency in multi-processor systems The memory hierarchy in multi-processor systems is composed of local CPU caches (L1 caches), shared CPU caches (L2 caches) and the main memory. To explain cache coherency we will ignore the L2 cache and only consider the L1 caches and main memory. WebbProcessor cache is organized in several levels, most current processors have three levels of this memory, known as L1, L2 and L3 cache. The lower levels are the fastest, but have less capacity, while the higher levels are a little further from the controller and take a few more cycles to access, but have greater capacity.
