Reconfigurable and low power 2D-DCT IP for ubiquitous multimedia streaming

An energy efficient architecture for the discrete cosine transform is presented. The proposed IP is intended to be used as the transform stage in a mobile H.263 codec. In particular, it seems well suited for an FPGA implementation since, after a complete place and route process, it is able to sustain a full-motion PAL video streaming operating at a frequency of 74 MHz with a dynamic power dissipation of just 39 mW.
