Abstract

The present invention relates to a method, device and SOC system for discriminating runaway CPU programs. The SOC system includes a CPU runaway monitoring device deployed on the system bus and configured by CPU coordination management. The CPU runaway monitoring device is configured with hardware Trap address space and trap code, the discriminating method of this CPU program running away comprises: configure the hardware trap address space and trap code of CPU running away monitoring device, and preset trap hit function; Monitor CPU in real time by described CPU running away monitoring device The addressing address on the system bus; quickly identify the runaway of the CPU program, and realize different operations according to the hit function set in the CPU runaway monitoring device. When the CPU runs away, respond in real time according to the preset operation behavior to correct the error; it is convenient for debugging and testing during SOC development, and quickly locates difficult problems; it is convenient for real-time detection of system error running status in SOC chip application scenarios, minimizing Unnecessary loss caused by system failure.

Description

technical field [0001] The invention belongs to the technical field of SOC system development, and in particular relates to a method and device for discriminating CPU program running away and an SOC system. Background technique [0002] The development and application of SOC system is more and more extensive, and has been extended to all walks of life. The SOC system is highly specific, so how to ensure the stable and controllable operation of the system is very important. However, in embedded development and actual higher real-time application scenarios, due to bugs in the program itself or some external interference, sometimes the CPU core scheduler in the MCU of the SOC system will fail, resulting in a system crash. [0003] To sum up, in the prior art, there is still no effective solution to the problem that the SOC system cannot effectively monitor program errors due to various reasons. At this time, a method for quickly detecting the running of the CPU program is nee...
