Debugging information processing method, device, electronic equipment, storage medium and system

Abstract

The application discloses a debugging information processing method, device, electronic equipment, storage medium and system. The system includes: a system-on-chip SoC used to obtain a write pointer when triggering the output of debugging information, and the write pointer is used to represent the ring Buffer the start address of this write; write debugging information to the ring buffer according to the write pointer, and update the write pointer; the terminal is used to read the write pointer and read pointer through the preset interface; judge whether to read or not according to the read pointer and write pointer Get the debugging information in the ring buffer; if so, read and output the debugging information according to the read pointer and the write pointer, and update the read pointer. The ring buffer can complete the storage of debugging information, and can accurately locate the reading position of debugging information through the read pointer and write pointer, so that the terminal can complete the acquisition of debugging information in the embedded processor according to the reading pointer and writing pointer, and improve the efficiency of debugging information acquisition .

Description

technical field [0001] The embodiments of the present application relate to chip technology, and in particular to a debugging information processing method, device, electronic equipment, storage medium and system. Background technique [0002] Large-scale system-on-a-chip SoC (System-on-a-Chip) designs increasingly use core processor cores for the control of SoC internal modules. The program running on the SoC embedded processor needs to be developed and debugged with the hardware module controlled by the processor to ensure the reliability and stability of the function. [0003] During the debugging process of embedded software, developers need to obtain the debugging information of the key nodes of program execution. But at present, R&D personnel can only determine the running result of the program by looking at the limited register values. Every time you want to view new running information, you need to change the program again, and output the corresponding information ...

AI Technical Summary

Problems solved by technology

However, at present, R&D personnel can only determine the program running results by viewing limited register values.

Every time you want to view new running information, you need to change the program again, and output the corresponding information to the general-purpose register, resulting in huge labor costs

It can be seen that the efficiency of obtaining debugging information in SoC embedded processors is currently low.
