Description

technical field

[0001] The invention relates to an on-chip dynamic tracking method of a microprocessor, which can be applied to 8051 series single-chip microprocessors, and can also be applied to other microprocessors and microprocessor fields. Background technique

[0002] Dynamic Trace (Dynamic Trace) refers to the process of recording the track information of program running in real time, and transmitting this information to an external debugging tool for analysis and debugging by some means. In the debugging and development process of embedded systems with microprocessors as the core, in order to facilitate the capture of high-speed signals and debug the processor, such as checking, recovering, and modifying according to the program execution history, it is necessary to record the high-speed running time of the processor. traces of. Therefore, in most devices such as logic analyzers and in-circuit emulators, there are tracking components used to dynamically track the ru...
