In a computer, the entire memory can be separated into different levels based on access time and capacity. Figure 1 shows different levels in the memory hierarchy. Smaller and faster memories are kept ...

I have a certain basic understanding of how CPUs are made up with functional blocks, stages in a pipeline, why instructions are decoded and dispatched, and a naive understanding of cache hierarchy.

The development of caches and caching is one of the most significant events in the history of computing. Virtually every modern CPU core from ultra-low power chips like the ARM Cortex-A5 to the ...
