【 摘 要 】

Recent years have witnessed the emergence of microprocessors that areembedded within a plethora of devices used in everyday life. Embeddedarchitectures are customized through a meticulous and time consumingdesign process to satisfy stringent constraints with respect toperformance, area, power, and cost. In embedded systems, the cost ofthe memory hierarchy limits its ability to play as central arole. This is due to stringent constraints that fundamentally limitthe physical size and complexity of the memory system. Ultimately,application developers and system engineers are charged with the heavyburden of reducing the memory requirements of an application.This thesis offers the intriguing possibility that compilers can playa significant role in the automatic design space exploration andoptimization of embedded memory systems. This insight is founded upona new analytical model and novel compiler optimizations that arespecifically designed to increase the synergy between the processorand the memory system. The analytical models serve to characterizeintrinsic program properties, quantify the impact of compileroptimizations on the memory systems, and provide deep insight into thetrade-offs that affect memory system design.
