Ultra low-power FSM for control oriented applications
Résumé
In this paper, we propose an approach combining the use of distributed hardware tasks implemented as finite state machines (FSM) and power gating techniques to obtain ultra low-power implementations. We target for control dominated applications represented as control task graphs, and propose a complete flow including a C to hardware task compiler. Our approach is validated experimentally and shows impressive improvement over software implementation on leading edge low-power microcontrollers such as the MSP430.
