本文采用高速数字信号处理器 DSP 与AD/DA 系统构成硬件仿真器。将仿真算法移植于DSP 中，通过AD/DA 实现模拟量的输入，输出。并通过接口与PC 机相连，实现参数的输入，控制和显示。关键词 DSP AD/DA 仿真接口Abstract: This study introduces a method to form a hardware simulator by using ahigh-speed Digital Signal Processor and AD/DA system. The arithmetic of simulating isembedding in DSP. The input and output of simulative signal are realized through AD/DAchannels. And by connected with PC, the input, control and display of the parameter arerealized.Key Words: DSP AD/DA Simulator Interface
