EIA的基于NIT和Multi-Core的面向应用调节架构

NIT and Multi-Core based application tuned processor architecture for EIA

资源受限的嵌入式系统中运行的应用程序与运行于桌面系统的应用程序有显著的不同,需要考虑应用本身的需求,也要更多地关注体系结构对于计算所提供的指令级和微指令级的支持。阐述了与嵌入式Intel架构(EIA)研究有关的重要问题,提出了一个基于Intel多处理器核技术的嵌入式应用处理器解决方案,其核心思想是提供可定制的计算单元用于对特定计算的适应。这个方案与普通多核技术及可配置处理器架构的差别在于通过粗粒度并行机制获得计算资源的定制以便适应嵌入式系统计算的特殊性。

Applications for constrained embedded systems require careful attention to the match between the application and the support offered by the architecture,at the ISA and microarchitecture levels.In this paper,we address our ideas using tunable architectures to develop an understanding of an application＇s performance and to enhance its performance with respect to customized module.Especially,this paper addresses the challenges associated with the research issues about Embedded Intel Architecture（EIA） ,and furthermore,figures out a draft about how to make a unified approach to combine multiple EIA cores as a whole embedded computing solution to industry application.In this solution,coarse-grained parallelism mechanism is used instead of both dual cores and configurable architecture to achieve ILP in embedded system.
