摘　　要：本文在研究ADSP21062从片外Flash加载过程的基础上,设计了一种通过RS232C接口对ADSP21062的片外Flash在系统编程的方法,给出了实现该方法所需的硬件构成和软件构成,并详细介绍了独特软件的功能,最后给出了使用该方法进行在系统编程的具体步骤以及实现结果。这种方法具有设备简单、操作方便和传输可靠等特点,解决了以DSP为核心的应用系统软件维护和升级问题。Based on the study of the boot loading process from outer-chip Flash of ADSP21062, an in system programmable technique via RS232C interface was designed for outer-chip Flash of ADSP21062. The hardware components and software components for realization of the technique were presented, and the functions of some unique software were introduced in detail. Lastly the detailed process of this in system programmable technique and the result of testing were given. Characteristic of this technique such as simple construction, convenient operation and reliable transmitting enable it deal with maintenance and updating problems for DSP core aoolication software.
