Problems solved by technology

Since the instruction register of the processor is used in the debugging process, it needs to be protected after entering the debugging mode and the register information of the normal operation of the program needs to be restored before exiting the debugging mode, resulting in long debugging time and low efficiency

Abstract

The invention provides a processor debugging method. The processor comprises a reconfigurable computing array, wherein the reconfigurable array comprises a plurality of processing units and a plurality of registers corresponding to the plurality of processing units. The method comprises the following steps of: receiving a debug instruction, controlling at least one processing unit to switch between a using state and a non-using state by a token to control the reconfigurable computing array to execute the debug instruction, generating debugging data and storing the debugging data in the registers corresponding to the at least one processing unit and the debugging data in the registers corresponding to the at least one processing unit is imported. The invention also provides a processor debugging system and a computer readable storage medium. According to the embodiment of the invention, the debugging efficiency of the reconfigurable processors can be improved.

Description

technical field [0001] The present invention relates to the field of electronic technology, and more specifically, to a processor debugging method and system. Background technique [0002] As the SoC becomes more complex, chip verification and debugging becomes more and more difficult. The traditional debugging technology is that the debugging host generates a debugging request by setting a certain bit of the register, and the processor enters the debugging mode after receiving the debugging request, and makes the debugging response signal valid. When in debug mode, the processor stops working and is isolated from the rest of the system. At this time, the core of the CPU no longer fetches instructions from the read-only memory, but the debugging host pokes the instructions that need to be executed by the processor into the instruction register of the processor through the interface. Select the appropriate instructions and control the execution of these instructions, and th...
