ABSTRACT:
The present invention relates to a method and apparatus for efficiently outputting words from an N-way set-associative cache. In one embodiment, the cache tags contain information indicating which set contains a line holding data succeeding the last word in the line accessed during a cache read. For a cache which outputs M words for each access, when the addressed word is within M-1 words of the end of the line, the cache will output all the words from the accessed word to the end of the line and the remainder of the M words from a succeeding line in whatever set is indicated by the pointer.
