摘　　要：以改进型Farrow结构滤波器为核心,设计了音频异步采样率转换的IP Core,并利用Simulink和硬件描述语言仿真器ModelSim构建服务器/客户端形式的仿真平台,实现对算法IP的联合仿真验证。实验结果表明,所设计的IP在信噪比等各方面均符合设计要求,该仿真方法高效、可行。Taken the improved Farrow structure filter as its center, the IP Core for audio asynchronous sample rate conversion was designed and emulated by co-simulation platform. The platform consisted of Simulink and ModelSim, and they worked as server and client respectively. The result shows that, the IP can meet the require of the design, and the co-simulation method is of high-efficient and feasible.
