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.

Abstract: An apparatus indicating the position of an adjustable lever, such as a control lever in a digital audio console, is described. A frame member constrains movement of the adjustable lever. The lever is operatively connected to an encoder apparatus, such that movement of the lever causes movement of the encoder apparatus to provide an indication of position of the lever within the frame member.
