Abstract
A plurality of processors form a network used to communicate with one or more peripheral devices and the system control processor. One processor is dedicated to at least one peripheral device. Since the system control processor is not burdened with the relatively slow communications protocol with the peripheral devices, it is free to do other tasks which improves the overall system performance. Communication protocol between the dedicated processors allows for local and global communication.
