Abstract
A parallel implementation of a DCT-based motion estimation algorithm (DXT-ME) for 2D images/signals is presented for a parallel scalable DSP system called PARNEU. PARNEU was used to test the performance of the parallelism. The DCT-based motion estimation can be used for video coding instead of the more frequently used full search block-matching approach (BKM-ME). The DCT-based system has lower computational complexity compared to the BKM-ME and it can result in a higher system throughput. Data parallel implementation scales very well and the performance measurements are promising compared to the traditional methods.
