The invention relates to a method for measuring the internal interrupt response time and restoration time of a CPU based on a logic analyzer. The method includes the following steps that S1, the CPU is in matched connection with the logic analyzer respectively through a GPIO1 port and a GPIO2 port; S2, before a software triggerable interrupt is triggered, the level of the GPIO1 port is overturned; S3, the selected software triggerable interrupt is triggered, and level signals of the GPIO1 port is continuously overturned for N times; S4, after the software triggerable interrupt is restored and the GPIO1 level changes, the logic analyzer stops acquisition of the level signals corresponding to the GPIO1 port and the GPIO2 port, and the recorded level signals corresponding to the GPIO1 port and the GPIO2 port are analyzed to determine the internal interrupt response time T1 and the restoration time T2. The method is convenient to operate, can achieve accurate measurement of the internal interrupt response time and the restoration time of the CPU and avoids deviations of operating time and timing sequence analysis and a system.
