ABSTRACT:
The present invention is directed to an integrated data processing system that includes a general purpose (GP) CPU core for processing data in accordance with a GP instruction set and a digital signal processor (DSP) module for processing data in accordance with command-list code. The DSP module is operable to execute the command-list code independent of and in parallel with execution of the GP instruction set by the CPU core. The system also includes a mechanism for DTMF detection.
