Abstract
A discussion of a local memory with at least a command block section and a cache section that facilitates an efficient interrupt processing. The command-block section is allocated on a per interrupt basis and contains pointers to cache-lines. When an interrupt is recognized an interrupt, the proposal uses the pointers in the command-block to prefetch the corresponding cache-lines from the cache section of the local memory, which it loads into its local cache buffer. Thus, when the CPU recognizes an interrupt, the information for the context-switch is already available in cache.
