PROCESSOR CACHE MEMORY AS RAM FOR EXECUTION OF BOOT CODE

摘要

In one embodiment, a computer boot method allows choosing a predetermined data block alignment for a cache that has multiple cross processor interactions. A cache RAM column of a cache as RAM system is loaded with a tag to prevent unintended cache line evictions, and boot code is executed, with the preloaded cache RAM appearing to the exe­cuting boot code stream as a memory store.
