Control dominated embedded systems have to be designedfor fast reaction to asynchronous external eventsoccurring in the environment. Such systems must be ableto perform signal emission, signal polling, preemption andpriority resolution efficiently. Current microprocessors andmicrocontrollers, however, have no direct support for suchtasks and employ indirect mechanisms such as polling (viaa port) and interrupts. In this paper, we propose a new processorcore having architectural support for reactivity at theinstruction level. The new processor core (called REFLIX)is an extension of an existing open source processor (FLIX)core with additional instructions to support reactivity. Initialbenchmarking results (for some control dominated programs)show that REFLIX performs, on an average, 5.92times faster compared to FLIX and has 77% code size reductionwhen compared to some conventional processors.
