Abstract

Within a dual stream processor (DSP) system, both processors share a common basic storage module (BSM) and its related control circuitry. Furthermore, each processor operates independently of the other, requesting access to the BSM at various times as directed by its instruction stream. The BSM controls must, therefore, be capable of fielding randomly submitted BSM access requests and dynamically allocating the BSM to one processor or the other. This is accomplished as follows: 1. When a processor submits a BSM access request, two general conditions are possible. The BSM and its controls are "Busy" servicing a BSM access request for the other processor, or they are not.
