1. A method for stuffing instructions in a processing pipeline of a multi-threaded digital signal processor for improved software instruction debugging operations, comprising: writing a stuff instruction into a debugging process registry associated with a debugging process; issuing from a core processor a debugging process control resume command during a predetermined stage of executing on a predetermined thread; providing the stuff instruction to the core processor; indicating to the core processor to execute the stuff instruction during the debugging process; and executing the stuff instruction in association with the core processor process and the debugging process.
