Nested loop processor for sequential computer program - uses memories to hold loop data, loop count, and return addresses to command table to dispatch to loop processing system

Abstract

Abstract The processor uses stored values of start and finish of loops to facilitate processing of nested program sectors, and also holds target addresses for entry to and exit from the loops. The information required for program transfers is then immediately accessible rather than obtained after a lengthy sequential scan. The controlling processor is coupled to the loop controller which has memories holding loop count requirements, and counter registers which count the executed loops. The restart of each loop is held in another memory which redirects the program to the command table from which the processor obtains the next instruction.
