This paper research an improved fast algorithm of EZW based on wavelet transform agreeing with running on high speed DSP.The algorithm of EZW is improved through analyzing data compression flow of traditional EZW and processing method of DSP.Consequently the speed of the algorithm running on DSP is greatly enhanced and the algorithm is applied to a certain item of image compression that rate of input data is big.The result of application is very good.
