ABSTRACT:
A technique for providing a dirty line cache to supplement a cache memory, in order to improve caching performance for a processor in a computer system. A fully-associative cache memory is coupled to operate with a main cache memory at a particular level of the cache hierarchy. The supplemental cache is termed as a dirty line cache, since it only stores dirty cache lines. In the preferred embodiment, the dirty line cache is implemented in a write-out buffer of a write-back or write-through cache.
