ABSTRACT:
A sequence of instructions for a processor executing a plurality of real time programs is supplied from a memory having a set of memory locations. A controller is coupled to the memory for replacing a program with a replacement program. The controller disables writes in response to instructions in the sequence from a particular group of memory locations with idle or no-operation instructions in response to a command. A memory interface is coupled to the memory and to the controller through which new instructions for the replacement program are written to the particular group of locations. The technique is applied especially for audio signal processors with a need for dynamic replacement of active voice programs.
