High efficient two dimensional multi-level discrete wavelet transform algorithm for DM642 signal processor

At the present time two dimensional multilevel discrete wavelet transforms are widely used in the image and video compression area. Compression algorithms are frequently implemented on digital signal processors, because such an implementation is most flexible. The first step for wavelet-based image compression is the multilevel discrete wavelet transform and it should be done fast and efficient. The proposed high speed algorithm intended for embedded video compression systems is based on Texas Instruments DM642 digital signal processor. An algorithm is developed for 2D DWT computation under low high-speed memory condition
