ABSTRACT:
An electronic asynchronous digital controller for use in microprocessors, computers and other digital systems. The controller stores a present state code which is classified into one of at least two state code classes, such as in either even or odd parity. A programmed instruction subsystem analyzes system inputs and present state code information to provide transition instructions indicating whether a state code transition should occur and the appropriate type of transition. Circuitry is included to assure that transitions only occur from one state code class into a different state code class, preferably by changing a single state code bit. Transition can also only progress if all previous transitions have been completed. The invention further includes methods for asynchronously controlling digital systems.
