CIRCUIT, METHOD, AND PROGRAM FOR PROCESSING SHARED DATA, INFORMATION PROCESSOR, AND INFORMATION PROCESSING SYSTEM

摘要

PROBLEM TO BE SOLVED: To generate the details of a discrepancy (a difference) between data in the memory device of a self-system and data in the memory device of another system. SOLUTION: A main storage control part 102 reads reading data from a main storage part 103 by a difference request with a shared address from a processor 101. A shared memory communication control part 104 outputs a main storage reading request to an information processor 200 via an inter-system communication means 300. The information processor 200 reads the reading data from a main storage part through a main storage control part 202 and a shared memory communication control part 204 by the main storage reading request, and outputs the data read reading data to an information processor 100. The main storage control part 102 inputs the reading data through the shared memory communication control part 104, generates difference between the inputed reading data and the reading data from the main storage part 103, and outputs the difference to the processor 101.
