DATA-DRIVEN TAG TABLE APPARATUS, DATA-DRIVEN CACHE MEMORY, AND READ AND WRITE METHOD IN DATA-DRIVEN CACHE MEMORY

摘要

PPROBLEM TO BE SOLVED: To comparatively increase throughput for continuous access by a comparatively simple configuration. PSOLUTION: A packet supplied to a diversion path 71 is sequentially branched off and transferred according to its destination address, and selectively supplied to one tag line of a tag line array 72 to determine a cache hit/cache miss hit and to decide a page address, and the packet is branched off and transferred at a branch node 77 according to the cache hit/cache miss hit to a diversion path 20 side or an input/output interface 81 side. With respect to a packet supplied to the diversion path 20, according to its destination address, partial storage data in one storage line on a storage line array are selectively read out to generate a read data packet which is transferred to an input/output interface 81 via a merging path 40 and a merging node 82.
