Resumen
This paper deals with the implementation onto an FPGA of a low power video decompression system that complies with the H.263 standard. Four different architectures for the 2D-IDCT module have been implemented, looking for the reduction of the decoder�s dynamic power consumption. Low power techniques employed in this work consist of bit-width reduction in MAC operations (low precision multipliers), avoiding block null processing, and memory bus commutation reduction. Results are very promising in terms of power consumption, saving up to 70% in the 2D-IDCT module, and up to 74% in the whole H.263 decoder.
