Abstract

This paper proposes an efficient hardware implementation of SPIHT(Set Partitoning In Hierarchical Tree) algorithm for image compression with the discrete wavelet transform. An efficient technique to scan the coefficients which are located in partitioned spatial orientation trees by DWT is considered in terms of counter fields for sorting pass and refinement pass. The proposed image compression method using SPIHT has been modeled in VHDL and has been implemented by use of both TMS320C6000 as a DSP and Virtex2 as a Xilinx FPGA.
