Parameterized Systems-on-a-ChipAbstractIncreasing silicon chip transistor capacities have enabled the integration of complete digital systems, including microprocessors, memories, coprocessors and peripherals, on a single chip. However, the number of transistors has become so large and time-to-market constraints so small that designers of embedded systems often can't utilize all those transistors. Thus, designers are increasingly using pre-designed architectures, or programmable platforms, to form all or part of a system. Such platforms must adapt to different power, performance and size constraints found in different applications. Parameterizing those platforms is one way to achieve such adaptability. We demonstrate that a wide range of power/performance tradeoffs can be obtained for a single application just by varying certain cache and bus parameters, we describe an environment under development as part of UCR's Dalton project intended to provide rapid power and performance evaluation of large numbers of parameter configurations, and we point to the need for research focus on parameterizing systems-on-a-chip platforms.Presentation Slides
