Wireless channel allocation plays as an important role in the design of wireless network, as it greatly influences the throughput and performance of the network. Based on the measurement over a small test-bed, we find the relationship between network throughput and interference. We introduce a wireless channel allocation model, which is able to minimize the network interference. Based on these works,...
This paper proposes an efficient architecture, which can perform multiple 8×8 transforms for both H.264/AVC and VC-1 decoders. The hardware design which supports multiple standards becomes more and more important. By designing a unique data flow for VC-1 8×8 inverse transform, the H.264/AVC and VC-1 8×8 inverse transforms are realized in a hardware sharing architecture. The proposed multiple transforms...
In this paper, an efficient mode decision algorithm and a high throughput hardware architecture with eight-pixel parallelism for improving the H.264/advanced video coding intra coding efficiency are proposed. Based on the inherent features of the discrete cosine transform, the input block is first transformed and then analyzed to determine its texture directional tendency. A few candidate modes are...
In this study, we purpose an efficient buffered crossbar switching architecture with multiple multicast virtual output queues called kMVOQ-CPX switch. The kMVOQ-CPX switch consists of N virtual output queues (VOQs), k multicast VOQs , an (N+k) x N buffered crossbar fabric, N+k Input scheduler and N output scheduler. It has the features of simple architecture and great capability to support multicast...
