چکیده

This brief paper proposes an efficient multi-input/multi-output VLSI Folded Architecture (MIMOFA) for two-dimensional lifting-based discrete wavelet transforms (DWT). In comparison with other 2-D DWT folded architecture, the advantages of the proposed architecture are 100% hardware utilization, fast computing time (10 times of the parallel filters), regular data flow, and low control complexity, making this folded architecture suitable for next generation image compression systems. The novelty is the simplicity and generality to construct the MIMOA, which is a high-speed the design and implementation of an image transform coding algorithm based on the discreet wavelet transform (DWT) SPIHT is computationally very fast and among the best image compression algorithms known today. According to statistic analysis of the output binary stream of SPIHT encoding, propose a simple and effective method combined with Huffman encode for further compression
