Abstract
The disclosure provides a processor checking method, a checking device and a checking system. The method includes acquiring a first access record of the processor to a first memory during a running process, the first access record including reading-operation information; acquiring a second access record of a checking device to a second memory during a replay process, the second access record including first reading-operation information, the first reading-operation information being reading-operation information corresponding to a case in which a first access of the checking device to a same address during the replay process is a reading operation, and determining, based on the first access record and the second access record, whether or not the processor reads during the running process a memory address that is not any one of addresses included in the second access record.
