Abstract
A processor comprising at least one processing module, each processing module comprising: an execution pipeline; memory; an instruction fetch unit comprising operable to switch between an operational mode and a debugging mode, the instruction fetch unit being configured so as, when in the operational mode, to fetch machine code instructions from the memory into the execution pipeline to be executed; and a debug interface for connecting to a debug adapter. The debug interface comprises a debug instruction register enabling the debug adapter to write a machine code instruction to the debug instruction register, and wherein the instruction fetch unit is configured so as, when in the debug mode, to fetch instructions from the debug instruction register into the pipeline instead of from the memory.
