Abstract
Cache memory is managed to update the data stored in the cache regardless of whether the address being operated upon is designated as cache inhibited. In this way, the contents of the cache are coherent with main memory so that when the processor redesignates a noncacheable range of addresses to be cacheable, the cache does not need to be flushed. Read operations follow cache inhibit faithfully.
