Abstract :
A wavelet-based parallel implementation is presented for image encoding on a multi-DSP system. The implementation is utilizing the discrete wavelet transform (DWT) and is realized in parallel processor architecture. The implementation has a very flexible architecture, which allows addition of extra slave processors (SPs) to the system whenever more computational power is needed. Performance of the implementation is measured and compared to a sequential reference implementation. Experimental results show that the parallel implementation is very efficient and overpowers the sequential counterpart considerably
