In this paper, the author describes the wavelet packet decompostion(WPD) algorithm of EEG signal on digital signal processing (DSP) chip. The analyse of DSP hardware features and wavelet packet principle illustrate the relationship between them and then demonstrate the feasibility and celerity of the algorithm. Furthermore EEG signal is divided into equal frequency band through the CCS and then classified between left and right hand motor imagery with the way of power spectrum. Results indicate that the method is correct.
