Optimization design of efficient FIR filter based on AltiVec

随着需求的发展,信号处理系统对实时性的要求越来越高,这就要求对涉及到的信号处理算法的运算时间有了严格的限制。本文介绍了一种在PowerPC平台上,基于AltiVec技术的FIR滤波器设计方法。仿真实验表明,此种FIR滤波器的实现方法运算速度快,实时性好,性能优于在传统DSP平台上的FIR滤波器设计方法。

With the development of demand, the requirement of real-time signal processing system is higher and higher. This requires to involved in the signal processing operation time had the strict limits of the algorithm. This paper introduces FIR filter design method based on AltiVec technology on a PowerPC platform. Simulation results show that, this kind of method to realize the FIR filter arithmetic speed, good real-time performance. Performance is superior to the traditional FIR filter design method of DSP platform.
