Abstract
A processor (e.g., a Digital Signal Processor (DSP) core) rewinds a pipeline of instructions upon a watchpoint event in an instruction being processed. The program execution ceases at the instruction in which the watchpoint event occurred, while the instruction and subsequent instructions are cancelled, keeping the hardware components associated with executing the program in their previous states, prior to the watchpoint. The rewind is such that the program is refetched to enable execution to continue from the instruction in which the watchpoint event occurred. The watchpoint event is executed in a 'break before make' manner.
