Dyadic DSP instruction processor with main and sub-operation functional blocks selected from each set of multiplier and adder

摘要

A dyadic digital signal processing (DSP) instruction processor including a first DSP functional block to execute a main operation of a dyadic DSP instruction and a second DSP functional block to execute a sub operation of the dyadic DSP instruction with data paths of each selectively configured to execute the main operation and the sub operation of the dyadic DSP instruction. A voice and data communication system has a first gateway and a second gateway coupled to a packetized network, each gateway having a network interface including the dyadic DSP instruction processor. An application specific signal processor with a signal processor having a first DSP functional block to execute a main operation of a dyadic DSP instruction and a second DSP functional block to execute a sub operation with multiplexers coupled to the first DSP functional block and the second DSP functional block to selectively configure data paths thereto.
