德州仪器公司的C6x系列DSP芯片带有功能强大的编译和调试集成环境CCS。用CCS调试软件时观察寄存器或是存储区变量最常用的方法是单步运行或者设置断点,然后在WATCH窗口中观察每个变量的值。但这种经典的调试方法不能实时反映数据的变化 ,甚至可能导致错误。文章针对这种缺陷提出了DSP实时数据交换 (RTDX)技术以在不影响目标程序运行的情况下和主机进行实时数据交换。同时阐述了如何在图像处理算法调试时利用RTDX技术实现对图像处理结果在计算机上进行实时显示的具体方法
Texas Instruments C6x DSP chip series with powerful compilation and debugging integrated environment CCS. The most common way to observe registers or memory variables when debugging software with CCS is to either run in single steps or set breakpoints and then observe the value of each variable in the WATCH window. However, this classic debugging method does not reflect the changes in the data in real time and can even lead to errors. This paper proposes a DSP real-time data exchange (RTDX) technology to deal with such defects in real-time data exchange with the host without affecting the target program running. At the same time, it explains how to use RTDX technology to debug the image processing algorithm to realize the real-time display of image processing results on the computer
