Software Controls Cache Memory to Speed CPUs

Software Controls Cache Memory to Speed CPUs

Image: AMD Multicore memory: More processor cores—this AMD Opteron has six—means the computer has a harder time managing how memory moves into and out of the processor’s cache. A new process for managing the fast-access memory inside a CPU has led to as much as a twofold speedup and to energy-use reductions of up to 72 percent. According to its designers, realizing such stunning gains requires a big shift in what part of the computer controls this crucial memory: Right now that control is hard-wired into the CPU’s circuitry, but the substantial speedup came when the designers let the operating system handle things instead. The CPU uses high-speed internal memory caches as a kind of digital staging area. Caches are a CPU’s workbench, whether they’re holding onto instructions a CPU may need soon or data it may need to crunch. And from smartphones to servers, nearly every CPU...
