Abstract

An improved local area network interfacing system. The inventive system includes a frontplane circuit for connecting the interfacing system to a local area network and a backplane circuit for connecting the interfacing system to a host. A first internal bus is included for providing communication between the backplane circuit and the frontplane circuit. A processor is included for controlling the operation of the interfacing system. A second internal bus is included for providing communication between the processor and associated memory. An internal bus control circuit facilitates and controls communication between the first internal bus and the second internal bus. The dual internal busses of interfacing system of the present invention afford high speed operation with an inexpensive processor by allowing for input and output operations to be completed without being impeded by processor operations.
