摘要: 基于TI TMS320C5410,提出数字信号处理器(DSP)内的一种动态程序加载技术,研究并实现DSP的在线升级与资源优化再配置。利用该技术解决DSP中原有bootloader程序的局限性,使DSP在启动时可选择性地加载应用程序,实现DSP内资源的优化配置和程序运行过程中的动态程序加载与释放,对DSP内的资源进行优化再配置。通过开发设计在线程序写入,实现DSP内程序的在线升级与在线 调试。

关键词: 数字信号处理器, 动态加载, 优化再配置, 在线升级

Abstract: This paper proposes a technology for dynamic program loading based on TI TMS320C5410 DSP. By using this technology, the limitation in bootloader program of Digital Signal Processor(DSP) is solved and any bytes long program can be loaded selectively, optimal configuration of resources in DSP are implemented. Dynamic program loading and release in the running process is realized, the optimal reconfiguration of resources in DSP is done, and online update and online debugging of program in DSP are developed.

Key words: Digital Signal Processor(DSP), dynamic loading, optimal reconfiguration, online update
