专利汇可以提供Information processing unit专利检索,专利查询,专利分析的服务。并且PURPOSE: To enhance the agreement rate of retrieval of a data directory by providing a data transfer directory and assigning the block when data is transferred from a main memory.
CONSTITUTION: When a memory address is given from instruction execution part 3, data collation is performed by data existence decision part 21; and in case of agreement, data is read out from high-speed buffer memory 2. In case of disagreement, decision is performed by data transfer suspension existence decision part 11. Then, in case of transfer suspension, data is caused to wait in memory address register 41 till transfer completion. If data is not pertinent to any of transfer suspension data, the address above is registered in data transfer directory 31, and data transfer request is issued to main memory 1, and simultaneously, a new address is supplied to register 41 by execution part 3. Then, only when data transfer becomes a write operation for memory 2, the supply of the next new address is stopped, and the block is assigned to the data dirctory. As a result, the retrieval agreement rate can be enhanced.
