A host system includes a microprogrammed processing unit which couples a foreign processing unit to the main memory of the host system. The microprogrammed processing unit also couples to an interface connected to the foreign processor. During operation, the host processor transfers a channel command to the microprogrammed processing unit which is operative under firmware control to perform the various control functions required for initiating a particular job. In this manner, the various parameters and information necessary to dispatch a job of the foreign processor is accomplished expeditiously under the firmware control in response to commands issued by the host processor.
