DSP系统软件开发通常包括模拟阶段和仿真阶段。模拟在设计的最初阶段开始进行,不需要硬件支持,只需在计算机上运行软件模拟器,可实现代码的初步调试。仿真是将代码下载到目标板上调试、运行,一般需要利用JTAG。JTAG一端与DSP相连;另一端与主机相连,可实现代码下载、代码运行、 DSP system software development usually includes simulation and simulation stages. Simulation begins in the very first stages of design, eliminating the need for hardware support and simply running a software simulator on a computer to allow for initial debugging of the code. Simulation is to download the code to the target board debugging, running, the general need to use JTAG. JTAG one end connected with the DSP; the other end connected with the host, enabling code download, code operation,
