嵌入式操作系统在TMS320F28335平台上的移植

Transplantation of Embedded System on TMS320F28335 Platform

随着目前所使用DSP性能的不断提高,DSP所处理的事务越来越复杂,添加和更改功能越来越频繁,编制的软件规模也越来越大。如何提高软件的复用率、保证软件的实时性、降低软件开发难度是每个DSP开发者必须面对的问题。因此,引进实时操作系统是许多DSP系统较好的解决方案。文中分析了目前存在的嵌入式系统,设计了基于TMS320F28335的硬件数据处理平台,在此平台上移植了μC/OS-II实时操作系统,并给出详细的移植步骤及测试方法,给出了部分源代码。最后,根据移植过程中遇到的问题给出了一些需要注意的细节。

With the improving capability of DSP,it is more complex in processing affairs, much higher frequency in additions and amendments of functions and much larger scale of software. How to improve efficiency of reuse,how to assure real-time and reduce the difficulties of software development are problems that each DSP developer must face to. Therefore, the introduction of real-time operating system is a good solution for DSP system. Analyze the embedded systems at present, and design the digital processing platform based on TMS320F28335, and on this platform transplant μC/OS-II real-time operating system. Give the detailed steps of transplantation and testing methods, as well as part of the source code. Finally, according to the problems in the course of transplantation present some details need to pay attention to.
