Financial decisions should not be made based solely on the results from these calculators. It also adds to a growing body of recent work imploring hardware and software designers to rethink their distribution of work.The calculators are for limited informational purposes only. Stash may not be the final answer, but the paper asks the right question. By empowering hardware and software to do what each does best, stash improves both performance and energy. Hits in the stash are as efficient as a scratchpad, but (infrequent) misses incur a small hardware penalty. The stash redistributes the hardware-software burden – software determines what data should go into the stash, but relies on hardware smarts for address space conversion and coherence. Besides offering the proverbial cake as an audience prize, the presentation described a new memory organization called stash that gets the best of caches and scratchpads. Researchers at Illinois address this conundrum in a paper presented at the International Symposium of Computer Architecture – Stash: Have Your Scratchpad and Cache it Too. In practice, this is inefficient and scratchpads have remained an enticing but niche solution. Software must explicitly move data in and out of a different scratchpad address space and take responsibility for keeping coherent multiple copies in different address spaces. Its hardware memory structure is simple and efficient. And it is not always successful.Ī scratchpad moves the burden of managing fast accesses to software. The magic of caches is that this cleverness has been hidden almost entirely from software.īut this cleverness costs energy. Decades of hardware research has found clever ways to determine what data to keep in the cache, how to find it, and when to throw it out. While most readers will not face the last choice, it is important for saving time and energy in the devices we love by keeping frequently-used information close at hand.Ĭaches are the workhorse of modern computers, feeding the processor with data about 100X faster than main memory.
