 note = {A low power coprocessor in the microcontroller helps to save total power consumption. While the main processor is in a sleep state, the low power coprocessor can process the inputs and maintain responsiveness. However, inter-processor communication and processor power state management make development more complicated. In this paper, we address this problem by introducing a mechanism to switch a running processor to the functional reactive programming (FRP) language XStorm, which has an abstraction mechanism for modeling stateful behaviors. The proposed mechanism allows us to choose which processor to run in each state. Therefore, the switching of a running processor can be represented as a state transition. Our compiler can absorb differences in processor architectures and automatically generate programs for inter-processor communication and processor state management. As a result, developers can more easily describe system with coprocessors. We describe the proposed mechanism and report an evaluation on the power consumption and time of state transitions., A low power coprocessor in the microcontroller helps to save total power consumption.
