INFORMATION PROCESSING DEVICE AND METHOD FOR DETECTING FAILURE OF INFORMATION PROCESSING DEVICE

摘要

When a switch LSI (20) receives a memory access request for a memory (14) from a CPU (10), the switch LSI (20) converts the memory access request to a memory access signal and sends the memory access signal. At this point, a switch LSI (21) converts a memory access request issued by the CPU (10) to a memory access signal. Furthermore, the switch LSI (21) acquires the memory access signal output by the switch LSI (20). Then, the switch LSI (21) compares the content of a memory access indicated by the memory access signal converted by the switch LSI (21) itself with the content of a memory access indicated by the acquired memory access signal. If the content of the memory accesses do not match, the switch LSI (21) determines that the switch LSI (20) has failed.
