A dynamic multiple instruction stream multiple, data, multiple pipeline (MIMD) apparatus simultaneously executes more than one instruction associated with a multiple number of instruction streams utilizing multiple data associated with the multiple number of instruction streams in a multiple number of pipeline processors. Since instructions associated with a multiple number of instruction streams are being executed simultaneously by a multiple number of pipeline processors a tracking, mechanism is needed for keeping track of the pipe in which each instruction is executing.
