The SPIHT algorithm based on the wavelet transform has the high performance on the still image compression.An improved listless SPIHT algorithm suitable for the hardware is presented.The algorithm uses the state mark instead of the list to record the information of the partition of sets,and then simplifies the process of the coding as the Boolean calculation. According to the algorithm,a SPIHT coder is designed based on FPGA.Experimental results show that this improved listless SPIHT algorithm is simple,thus saving the resource and increasing efficiency.The method is efficient for realizing the image compression with a high speed by the hardware.
