摘要
随着计算机和微电子技术的飞速发展,数字信号处理已经应用到各个领域并且发挥着重要作用,但是在调试应用的时候为了能够实时观察信号,需要进行硬件仿真.基于这种情况设计了一种基于计算机并行接口EPP模式的TI公司DSP仿真器,该系统以边界扫描芯片ACT8990为核心,执行IEEE1149.1协议对DSP片内数据进行读写,并行接口控制模块SMC34C60实现CCS和ACT8990通过计算机并口通信,从而实现CCS通过仿真器对DSP的仿真.
With the development of computer technology and microelectronics,the digital signal process （DSP） has been applied in all kinds of fields and is playing a vital role. In order to observe real time signal in debugging application,emulating by hardware is necessary. So the DSP emulator based on the EPP mode for parallel ports of computers is designed. The system＇s kernel IC was ACT8990 that executes IEEEl149. 1 protocol, and write/read the data in chip of DSP. CCS communicating with ACT8990 via the parallel ports of computers was implemented by the parallel port interface IC SMC34C60. Thus the CCS implements the function of emulating the DSP by the emulator.
