PROBLEM TO BE SOLVED: To provide an interrupt signal information recording apparatus to automatically record the state of interruption signals for an information processing apparatus, which performs a plurality of interrupt processings. SOLUTION: Interrupt signals 109 to 111 are held in latches 204 to 206, and latching contents in the latches 204 to 206 are monitored in an interrupt status collecting part 202. If there is a change in the latching contents, the interruption status collecting part 202 notifies a DMAC 211; the DMAC 211 acquires the time, when receiving the notification from a calender IC 217 and makes a packet for latching the contents in each of the latches 204 to 206; and then the DMAC 211 writes the packet into RAM in the information processing apparatus via a system bus 114.
