ABSTRACT:
An application specific signal processor (ASSP) performs vectorized and nonvectorized operations. Nonvectorized operations may be performed using a saturated multiplication and accumulation operation. The ASSP includes a serial interface, a buffer memory, a core processor for performing digital signal processing which includes a reduced instruction set computer (RISC) processor and four signal processing units. The four signal processing units execute the digital signal processing algorithms in parallel including the execution of the saturated multiplication and accumulation operation. The ASSP is utilized in telecommunication interface devices such as a gateway. The ASSP is well suited to handling voice and data compression/decompression in telecommunication systems where a packetized network is used to transceive packetized data and voice.
