摘要
嵌入式系统设计的一个重要任务就是寻找硬/软件最佳搭配方案。随着系统复杂性的不断提高,采用嵌入式系统硬/软件协同设计是提高设计质量的有效手段。本文在讨论嵌入式系统设计一般方法的基础上,阐述了系统的硬/软件协同设计技术和硬件/软件划分方法,提出了以系统硬/软件划分策略为基础,系统组件的权重值为参考,组成元素划分为依据的设计理念,构造了基于移动环境的系统的硬/软件协同设计的EHSC(EmbeddedHardware/Soft-wareCodesign)模型。并依照此模型,实现了一种移动嵌入式系统“电子书包”阅读器的设计和开发。
An important task of embedded system design is to seek an optimal hardware/software codesign. With the growing complexity of the systems, embedded system hardware/software codesign becomes an effective way to improve design quality. On the discussion of general methods used in embedded system designing, this paper illustrates hardware/software codesign technology and their partitioning, proposes a design idea based on hardware/software partitioning, the weight of components and their partitioning, which leads to the construction of EHSC. Based on the module, a mobile embedded system-“Electronic Satchelis” developed.
