Abstract
PURPOSE:To realize the application of the read data with no access given to a main memory by registering the data given from the main memory with a write request received from a CPU or a channel device into a 2nd chache memory and using said data when a 1st cache memory has a misbit at the time of a read request. CONSTITUTION:The write data given from a channel device 13 connected to a CPU 12 or a magnetic disk device 14 when a block read request is given to a main memory 11 is weitten into a 1st cache memory 21 of a 1st chache control part 23 in the CPU 12 and at the same time registered into a 2nd chache memory 24 of a 2nd cache control part 26. If the memory 21 has a mishit when a memory read request is received from the CPU 12, no access is given to the memory 11 and the desired data is obtained from the memory 24. Then the block read is prevented to the memory 11 and the system throughput is improved.
