We have described and applied a technique for selection of processor cache configurations for low power using a parameter defined as a product of the cache miss rate and cache size. 1. Introduction ...

The memory hierarchy (including caches and main memory) can consume as much as 50% of an embedded system power. This power is very application dependent, and tuning caches for a given application is a ...

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 ...

The year so far has been filled with news of Spectre and Meltdown. These exploits take advantage of features like speculative execution, and memory access timing. What they have in common is the fact ...

The i7 supports the x86-64 instruction set architecture, a 64-bit extension of the 80×86 architecture. The i7 is an out-of-order execution processor that includes four cores. In this chapter, we focus ...

System-on-a-Chip (SoC) designers have a problem, a big problem in fact, Random Access Memory (RAM) is slow, too slow, it just can’t keep up. So they came up with a workaround and it is called cache ...
