In this paper, we study and analyze different Network-on-Chip (NoC) designs for MPEG-4/H.264 coding. The encoding and decoding processes of H.264 have been analyzed. We discuss the parallelism of H.264, and an open-source encoding program is used as a case study. The contribution of this paper lies in the NoC design method and performance evaluation of data parallel H.264 coder. It is shown in our...
Rectangular mesh and torus are the mostly used topologies in network-on-chip (NoC) based systems. In this paper, we quantitatively illustrate that the honeycomb topology is an advantageous design alternative in terms of network cost which is one of the most important parameters that reflects both network performance and implementation cost. Comparing with the rectangular mesh and torus, honeycomb...
A feasible and scalable per-core DVFS architecture for on-chip network is presented. The supplies are dynamically adjusted at a very fine granularity based on the local traffic status. The adoption of multiple voltage supply networks and power selecting transistors provides the architecture with scalability and feasibility superior to existing similar techniques. With high-level simulation using 65...
As the size of NoCs increases, power consumption and fault/variation tolerance have become two of the most crucial problems for system designers. To address these problems, we propose a NoC architecture based on a hierarchy of monitoring agents. By tracing the circuit properties at run time, the agents at different architectural levels are able to monitor and control over the whole NoC platform. This...
