Abstract
An architecture for interconnecting a plurality of remote processors to a primary processor. The architecture provides an improved interface and a communication channel for interconnecting the processors. The interface includes a commonly shared buffer which stores messages to be exchanged between the primary processor and the remote processors. A controller (microprocessor based) is provided to manage the buffer and the communication channel. The controller gives the primary processor direct access to the buffer periodically. Likewise, the controller uses a polling technique to enable each remote processor to communicate, over the communication channel, with the shared buffer.
