摘要

功能单元的数量会对VLIW处理器的性能和能耗产生重大影响。本文采用设计探索方法寻找最佳整数功能单元配置，以实现不同介质应用的最佳EDP(能量延迟积)结果。我们的实验结果定量地表明，整数功能单元的最佳数量应该与可以从应用程序中提取的指令级并行性相匹配，以最佳地平衡VLIW处理器的性能和能量。

Exploring Functional Unit Design Space of VLIW Processors for Optimizing Both Performance and Energy Consumption

The number of functional units can have significant impact on both the performance and energy consumption of VLIW processors. This paper uses a design exploration approach to find optimal integer functional unit configurations for achieving the best EDP (energy delay product) results for different media applications. Our experimental results quantitatively indicate that the optimal number of integer functional units should match the instruction level parallelism that can be extracted from the applications to balance both performance and energy optimally for VLIW processors.
