基于TMS320VC5509A的HPI引导过程的实现

摘要

TI的TMS320VC5509A DSP芯片提供了几种不同的引导配置，不同的配置决定了DSP复位后的初始化和代码引导方式。本文就TMS320VC5509A DSP的HPI引导过程进行了详细的设计，包括HPI的一级引导和二级引导，最后给出了HPI二级引导的软件和硬件的具体实现。%The TI TMS320VC5509A DSP chip provides several different boot configurations that determine the DSP initialization and boot way in which resetting code is used. This article carried out a detailed designof theTMS320VC5509A HPI boot process, including primary and secondary HPI boot process, and final y gives the software and hardware Implementationof the HPI secondary boot.
