用户期望未来的手持设备提供扩展的多媒体功能并具有长的电池寿命。这种类型的应用程序对（实时）性能和能耗都有很大的限制，迫使设计人员优化平台的所有部分。在这个实验中，我们专注于不同的处理器内核设计方案的嵌入式平台，包括指令存储器的层次结构对能源消耗的影响。结果表明，显着的改进，能源效率和/或性能，目前使用的RISC或VLIW处理器可以实现。我们的结论是，基于一个现实的应用程序的具体数据，不同的风格，包括可配置的硬件和指令集处理器，找到自己的方式到异构平台和设计师需要知道的权衡。其次，我们表明，对于相同的应用程序任务，一个高度优化的指令/配置存储器层次结构可以显着降低这部分的能耗，所以它形成了每一个能源感知设计的重要组成部分。
Users expect future handheld devices to provide extended multimedia functionality and have long battery life. This type of application imposes heavy constraints on both (realtime) performance and energy consumption and forces designers to optimise all parts of their platform. In this experiment we focus on the different processor core design options for embedded platforms, including the effect of instruction memory hierarchy on the energy consumption. The results show that significant improvements for energy efficiency and/or performance over currently used RISC or VLIW processors can be achieved. We conclude, based on concrete data for a realistic application, that different styles, including both configurable hardware and instruction set processors, find their way into heterogeneous platforms and designers need to be aware of the trade-offs. Secondly, we show for the same application task that a heavily optimised instruction/configuration memory hierarchy can significantly reduce the energy consumption of this part, so it forms a crucial part of every energy aware design.
