专利汇可以提供Cache memory system of parallel configuration专利检索,专利查询,专利分析的服务。并且PURPOSE: To improve hit ratio by constituting cache memory system by using comparison with a part of address data requiring no RAM access time and system requiring the RAM access time in parallel.
CONSTITUTION: The system is constituted mainly of an MPU 1 to output request address data, an address latch circuit 16 which receives that request address data and latches an address, first memory modules 2A, 2B, a second decode circuit 3, first data memories 4A, 4B, a first decode circuit 5, second memory modules 6A to 6D, second data memories 7A, 7D, a second replace circuit 15 for the second memory modules 6A to 6D, and so on. Namely, the comparison with a part of the address data requiring no RAM access time and the traditional system requiring the RAM access time are organized in parallel. Thus, it becomes possible to return a response signal for the high speed operation of the MPU 1 efficiently and quickly to the MPU 1, and simultaneously, since the degree of freedom of mapping for the inside of the cache memory becomes high, the hit ratio can be improved.
