CACHE SYSTEM WITH PRIMARY CACHE AND OVERFLOW FIFO CACHE

摘要

A cache memory system including a primary cache and an overflow cache that are searched together using a search address. The overflow cache operates as an eviction array for the primary cache. The primary cache is addressed using bits of the search address, and the overflow cache is configured as FIFO buffer. The cache memory system may be used to implement a translation lookaside buffer for a microprocessor.
