Abstract
A debugging mechanism receives arithmetic operation data inputs for causing an arithmetic unit to perform an arithmetic operation, and a control signal used for the arithmetic operation. The debugging mechanism includes a debug control unit which includes (1) a counter that performs a counting operation cyclically according to the processor clock operation, and (2) an OR circuit that receives the control signal and a counter signal that is output when the counter value becomes a specific value, and outputs an output signal generated by performing a logical OR operation of the control signal and the counter signal. The debugging mechanism also includes a debug storage unit which stores the arithmetic operation data, the counter value, and the control signal when the output of the OR circuit is valid.
