Implementation of moving-average filter algorithm and LZW algorithm based on FPGA

CHEN Shi-hai,PEI Dong-xing,ZHANG Qi (Key Laboratory of Instrumentation Science & Dynamic Measurement,Ministry of Education,North University of China,Taiyuan 030051)  
Considering the problems between data acquisition system for a long period of high-speed sampling and the limited data transmission and storage capacity,a solution for data compress based on FPGA is proposed.At the same time,in order to smooth the quantizing noise,before data compression using a filter as the pre-treatment technology.This paper introduces the basic theory of LZW algorithm and moving-average filter algorithm,describes in detail the methods to achieve two algorithms by FPGA.The experimental results show that the design scheme can effectively filter out the high-frequency noise of data,meanwhile,it obtains a good compression ratio and processing speed,and has a certain practical value.
