There are a few Multiple Instruction Multiple Data (MIMD) based architectures for best-basis algorithm presented in [2] for images or 2D signals and in =-=[5]-=- for 1D signals. In this work, we propose an architecture for wavelet packet based best-basis algorithm for images or 2D signals using Threshold function as an information cost. The architecture was a... |
