Commercially available OEM communications protocol controller chips are attachable to the using systems through direct memory access control. However, the real time programming requirements necessary to implement high speed data communication protocols often prevent functional use of the vendor chips at or near the actual rated speed of throughput. The system described below utilizes hardware logic circuits for performing some of the critical protocol functions intended to be performed by software in these OEM devices. A typical system is shown in the figure.
