This letter aims at optimizing the mapping of embedded applications on the hybrid network-on-chip (NoC) that intermingles multiple switching mechanisms. Specifically, we identify the critical characteristics of those switching mechanisms, deriving a new latency and energy model for this type of networks. A novel mapping scheme based on a branch-and-bound(More)
Stream programming model has received a lot of interest due to its naturally-exposed task, data and pipeline parallelism. Many researches concentrated on scheduling stream programs on multi-core systems. However, few of them consider the arithmetic unit utilization, which is a vital factor to determine the performance of multi-core systems. This paper(More)
Stream architectures have emerged as a mainstream solution for computation-intensive applications due to their rich arithmetic units. This paper proposes a multithreading technique based on a scheduling scheme of stream programs on clustered VLIW stream architecture, which aims at optimal arithmetic unit utilization without increasing energy consumption.(More)
The increasing high performance requirement of multimedia applications makes stream processors widely used for multimedia processing acceleration due to the powerful computation. Low power then becomes a critical challenge confronted by stream processors, especially in embedded and realtime situations. In this paper, a low power scheduling algorithm for(More)
