一、前言大规模集成电路技术(LSI)的发展,使得大规模数字信号处理技术可以廉价可靠地实现硬件化,这是以往的元件技术所做不到的。数字信号处理技术(DSP)是和计算机同时发展起来的技术领域,最初是作为数值计算和话音分析及合成等计算机模拟技术开展起来的。但是,随着LSI技术的发展,自从可以实时地处理以话音信号处理等为中心的快速处理以来,在通信领域得到了特别显著的发展。作为硬件技术,初期用数个集成 I. INTRODUCTION The development of large-scale integrated circuit technology (LSI) has enabled large-scale digital signal processing technology to be hardware-implemented with low cost and reliability, which can not be achieved by conventional component technologies. Digital signal processing (DSP) is a technology field developed simultaneously with computers. It was originally developed as a computer simulation technique for numerical computation and voice analysis and synthesis. However, with the development of LSI technology, a particularly significant development has been made in the area of ​​communications since the rapid processing centered on voice signal processing and the like can be handled in real time. As a hardware technology, early with a few integrated
