Abstract
Embedded systems typically combine a mixture of heterogeneous components, some that are software executing on general purpose CPUs, some that are off-the-shelf hardware components, and some that are application specific circuitry. A major challenge when designing and implementing such systems is the dissimilar models of computation exhibited by hardware and software targets. To successfully navigate this challenge, components must be implemented in a way that does not unnecessarily bias the implementation towards either computational model, allowing the components to be retargeted as application requirements change. This dissertation presents an approach to this problem using a functional programming language extended with monadic imperative and concurrency effects. We argue that these language features allow components to be implemented and compiled to either hardware or software targets. To demonstrate this claim, we detail the design of such a language, Oread. Moreover, we describe the compilation of Oread to both hardware, via VHDL, and software, via C. Using these compilation techniques, we describe the development of a digital processing component in Oread and the integration of that component into a larger system.
