One of the most important parts of a processor is the buffer memory, also called the cache. What is it responsible for and how does it work?

Cache, in its crude definition, is a faster memory which stores copies of data from frequently used main memory locations. Nowadays, multiprocessor systems are supporting shared memories in hardware, ...

The diagram below, which was taken from the Intel paper referenced in the introduction, gives a high-level perspective of the parts that must be added to the cache and memory hierarchy for the ...

Direct mapped means that every memory location maps to just one cache location. In the diagram, there are 4 cache slots.This means that Cache index 0 might hold memory index 0,4,8 and so on.

During idle machine cycles, the data are written from the cache memory to main memory or to disk. Write-back caches improve performance, because writing to the cache is faster than writing to main ...

Although providing much greater density than DRAM, PCM has longer access latency and limited write endurance to make it challenging to architect it for main memory. To address this challenge, this ...

The authors report on the design of efficient cache controller suitable for use in FPGA-based processors. Semiconductor memory which can operate at speeds comparable with the operation of the ...

Ever been curious how L1 and L2 cache work? We're glad you asked. Here, we deep dive into the structure and nature of one of computing's most fundamental designs and innovations.
