Abstract

In a machine control environment, a microprocessor provides control instructions via an output register to a plurality of devices or to portions of one device. In a highly interactive computer-machine environment requiring a diversity of programs in the microprocessor to effectively control a device, such as a machine tool, magnetic tape drive, internal combustion engine, magnetic disk subsystem, printers, transfer electrographic machines and the like, a goodly portion of the control store which contains the microprocessor instructions is dedicated to a plurality of output instructions by practicing the present arrangement where the number of output device addresses is limited. Not only can the output signals be speeded up, but also the actual number of output instructions can be substantially reduced.
