Abstract: Methods and systems are provided for debugging a program executing on a processor. In a first implementation, a processing system includes a processor configured for switching to a debug mode from a non-debug mode upon executing a software breakpoint. The system may include a program memory configured to hold instructions for a program, where the software breakpoint replaces at least one of the instructions. The system may also include an instruction replacement register separate from the program memory that is configured to receive the replaced instruction from any of the processor and an external debugger. The system may further include a control component that controls whether the processor fetches a next instruction for execution from the program memory or from the instruction replacement register.

Abstract: It is the object of the present invention to provide a mechanism to store and retrieve trace information in on-chip system memory of microcontrollers. A microcontroller comprises a microprocessor and a memory device accessible through a data bus and an address bus coupled to the microprocessor. The microcontroller includes on-chip debug logic coupled to the microprocessor. The on-chip debug logic includes a low speed debug port and a mechanism for temporarily storing trace data on the memory, wherein the trace data can be retrieved via the low speed debug port by a debug tool. A method and system in accordance with the present invention will lower the cost of implementation of trace features in microcontrollers, and strongly reduce the cost of supporting such features in debug tools.
