Embodiment Construction
[0062] A preferred embodiment of the present invention is described in detail as follows in conjunction with accompanying drawing:
[0063] The on-chip dynamic tracking method of this microprocessor adopts the following workflow (see figure 1 ) to realize the dynamic tracking of the processor running process:
[0064] 1) Several observation points in the program are specified by the debugger. In this example, n=8 is set, and there are 8 watchpoint address registers WPi (0-7) in total. Therefore, the debugger can arbitrarily set 0-8 watchpoints.
[0065] 2) Internal registers that need to be traced and recorded at each observation point are specified by the debugger. In this example, 24 commonly used internal registers are set for selection, and the selection of these 24 internal registers is independent of each other. The debugger can select 1 to 24 internal registers that need to be tracked and recorded according to the situation.
[0066] 3) Start the process of dynamic ...
