基于TMS320C6455 DSP自动加载及Flash烧写程序的设计

摘要

为了实现系统上电自动加栽程序，介绍TMS320C64x系列数字信号处理器（DSP）程序的各种引导模式，尤其对基于ROM的引导模式及引导过程进行详细的剖析，并以TMS320C6455DSP为例．提出一种不需转换格式就可通过烧写程序将用户程序写入Flash的方法，给出二次加栽程序的汇编和C语言实现的参考代码以及烧写程序的核心代码，并在实践中验证代码的正确性。%In order to load code automatically, introduces some boot modes of TMS320C64x series digital signal processor （DSP）, especially describes the boot mode and process in details through the external ROM. Taking the TMS320C6455 DSP as an example,puts forward a method which can write in the Flash directly without transform the format of user code. Gives secondary boot loading source codes in assemble language and C language. It has been proved right in the verified target.
