Abstract

A technique is described whereby interrupt driven state controller software allows multiple operations to be performed simultaneously, as used in personal computing systems. The concept is an improvement over previously implemented interrupt driven state controller software, in that the interrupt functions are under the control of unique queueing elements. These queueing elements allow interrupt instructions to relay the status of all actions as they are occurring during the processing of multiple computer controlled functions. The concept provides a means of controlling the sequence of actions, being performed and to be performed, while time controlled interrupts are used to control the operations requested. Unique retries are performed by treating the retries as just another action on the queue.
