STORED PROGRAM CONTROLLER WITH A CONDITIONAL BRANCH FACILITY AS FOR A VIDEO SIGNAL PROCESSOR
摘要
A video signal processor includes a stored-program controller which concurrently reads two instruction values from a program memory during each instruction cycle. The next instruction used by the video signal processor is selected from between these two values. If the current instruction indicates a conditional branch operation, the value of one of a plurality of conditions internal to the video signal processor determines which of these two instructions is selected. Otherwise, a value provided by the current instruction itself determines which of the two instructions is selected. This configuration of the stored program controller implements a conditional branch facility in which there is no delay in fetching an instruction for either value of the selected condition.
