LOG RECORDING DEVICE

PROBLEM TO BE SOLVED: To efficiently record a log.SOLUTION: A log recording device comprises: a log recording memory 10; an access control unit 6 for acquiring content of access from a CPU 1 to memory space; a log recording condition storage unit 7 for storing log recording conditions 11 defined by an address of an access destination, an access type, or a combination of them; and a log recording condition determination unit 8 for, each time the access control unit 6 acquires the access content, determining whether the acquired access content satisfies the log recording conditions stored in the log recording condition storage unit 7. The access control unit 6 stores in the log recording memory 10 the access content determined to satisfy the log recording conditions 11 by the log recording condition determination unit 8, and does not store in the log recording memory 10 the access content determined not to satisfy the log recording conditions 11 by the log recording condition determination unit 8.
