本文提出了一种基于 TMS32 0 C31串行接口的双通道实时数据采集处理系统的设计与实现方案 ,该设计以 TMS32 0 C31和 TL C32 0 AD5 0 C为核心器件 ,具有两个独立的 A/D,D/A通道 ,能够实现 32位浮点计算和 16位数据采集与回放。应用该系统进行归一化最小均方误差 (Normal-ized L east Mean Square,NLMS)算法实时自适应噪声抵消实验 ,实验结果表明 ,该系统能够实现实时的自适应噪声抵消 ,可广泛应用于实时语音信号处理等领域。
This paper presents a TMS32 0 C31 serial interface based on dual-channel real-time data acquisition and processing system design and implementation of the program to TMS32 0 C31 and TL C32 0 AD5 0 C as the core device with two independent A / D, D / A channel, to achieve 32-bit floating-point calculation and 16-bit data acquisition and playback. The system is applied to real-time adaptive noise cancellation experiment of NLMS algorithm. The experimental results show that the system can realize real-time adaptive noise cancellation and can be widely used in real-time Voice signal processing and other fields.
