Recently, many e cient parallel algorithms on the recon gurable mesh have been developed. However, it is not easy to understand the behavior of a recon gurable mesh. This is mainly because the bus topology can change dynamically during the execution of algorithm. In this work, we have developed JRM, a Java applet for visualizing parallel algorithm on the(More)
The crosstalk between single-ended and differential lines is investigated in this paper. First, the telegraphers equations for multiconductor line are applied. Then the differential pair is terminated respectively with T and Π termination networks, and the crosstalk from the single-ended trace to the differential pair is evaluated at the grounded resistors(More)
A novel approach to hardware implementation of H.264 block size decision is proposed, which is based on rate-distortion (RD) optimization. Utilization of RD cost for block size decision can improve up to 2.0 dB of PSNR in compared with conventional SAD/SATD based approaches. However, calculation of RD cost for a block incurs considerable computational costs(More)
