CFRP: A Functional Reactive Programming Language for Small-Scale Embedded Systems

Functional reactive programming (FRP) is a programming paradigm for reactive systems based on functional abstractions expressing time-varying values and events. In this paper, we present a strongly-typed pure FRP language named CFRP to show that FRP is beneficial for developing software for small-scale embedded systems. Although its design follows the tradition of signal based FRP languages, our compiler can generate stand-alone C++ code that can be deployed effectively on resource-constrained microcontrollers. Through an example, we show that CFRP supports a declarative, modular and clean manner of developing small-scale embedded systems.
