Abstract
A multiprocessor system includes a plurality of signal processors and a common unit processor. Each of the signal processors is connected to a different source of signals such as voice signals and performs one or more signal processing functions relative to the connected source. The common unit processor performs one or more functions for the signal processors on a shared synchronized basis. A signal processor adapter responsive to a source of clock pulses generates synchronous interrupts applied to the common unit processor and enabling signals in sequence to connect the signal processor in sequence to the common unit processor in synchronization with the interrupts. In addition, the signal processors are provided with ping-pong buffers at their inputs and outputs to enhance throughput.
