Abstract
Abstract A computer system for performing distributed processing, particularly of digital audio data, is disclosed. The system has a number of digital signal processors linked to a host computer through a time division multiplex bus. The system includes means for assigning to a particular processor a specific processing task or tasks, as well as a means for assigning additional specific processing tasks to that same processor to maximize its use. When the processor performing a specific processing task has reached its capacity, the system assigns a new processor to perform that task. To enhance the efficiency of the processor to perform the specific processing task, the processor cyclically runs a specific set of instructions for performing that specific processing task, and waits for the system to send it digital data to be processed.
