The advent of deep submicron processing technology has made it possible and desirable to integrate a processor core, a program ROM, and application-specific circuitry all on a single IC. As the complexity of embedded software grows, highlevel languages such as C and C++ are increasingly employed in writing embedded software. Consequently, high-level language compilers have become an essential tool in the development of embedded systems. Fixed-point digital signal processors are among the most commonly embedded cores, due to their favorable performance--cost characteristics. However, these architectures are usually designed and optimized for their application domain, and pose challenges for compiler technology. Traditional compiler optimizations, though necessary, are insufficient for generating efficient and compact code. Therefore, new optimizations are required to produce code of the highest quality in a reasonable amount of time. In this thesis the author presents techniques for co..
