SPIHT is the most well recognized coding algorithm due to its high performance. But SPIHT is unsuitable for high speed hardware implementation. An improved coding algorithm of SPIHT is introduced. The performance and rough pipeline architecture of the improved algorithm are presented. PSNR values for our algorithm are only slightly lower than SPIHTs, but the improved algorithm is suitable for hardware implementation with high speed because it can be mapped into systolic architecture.
