Abstract

A programmable interface or bus coupler 20 controls data transfers between two processors at rates required by different I/O devices. Bus couplers 20 attach between system channel 15 and I/O channel 30 and function to allow communication between system processor 10 and I/O processors 25. Bus coupler 20 controls cycle steals between system processor 10 and a corresponding I/O processor 25.
