AN APPARATUS FOR CONTROLLING ACCESS IN A DATA PROCESSOR

摘要

A computational unit comprises a processor having a plurality of processing elements, each having an arithmetic logic unit, and a controller for controlling the processor elements. The processor can provide a respectivef bit of a multiple bit word to each of the processor elements and enables signals to be transmitted between the arithmetic logic units to enable the units to perform a parallel operation on the bits of the multiple bit word. Extension circuitry is provided for selectively coupling one or more computational units together to combine their parallel processing capability.
