Abstract
An interface chip is capable of receiving requests from two processors and coordinating the flow of the data therebetween. The chip functions as a dual port controller for interaction of associated RAMs and processors of a voice processing system. A plurality of interfaces of the instant invention can be placed in communication with a host computer (PC) of a voice processing system that determines the priority of requests that are received from units of the system. The interface circuits are in communication with the host computer for the purpose of accepting requests in sequence and outputting data over a bus. The host computer is in communication with a RAM interface of each chip that interfaces local peripheral board processor through a dual port RAM which resides on the peripheral board. The interface chip contains the circuitry that creates communication with the resident RAM.
