Abstract
A state driven system includes a plurality of sub-programs and microcodes in storage. A plurality of peripheral units and an entity are connected to a common bus. Changes in state of the peripheral units are detected in a scanning mode, and in response to such state changes a state action table containing action commands is accessed for retrieving necessary action commands to drive a state processing table for assembling a combination of program addresses and microcodes. Programs associated with the addresses are retrieved from memory and executed, and logic cards are operated by given ones of the microcodes for operating the peripheral units in their changed states.
