Abstract

A method for performing manual operations, such as address compare equal stop, single cycle alter, etc., in a time slice controlled microprocessor with microprogramming, which avoids stopping the processor clock when any of the programs requires a manual operation. This problem is solved by assigning the manual operations to a specific program, which for the other programs in the multiprogram environment executes the manual operations required.
