Network-on-Chip (NoC) is a growing and promising communication paradigm for Multiprocessor-System-On-Chip (MPSoC) design, because of its scalability and performance features. In designing such systems, mapping and scheduling are becoming critical stages, because of the increase of both size of the network and appli-cation's complexity. Some reported(More)
The authors present a scheduling methodology for conditional execution of kernels onto single instruction stream/multiple data stream multicontext reconfigurable architectures. Data flow graphs are used to describe the target applications in which some kernels are conditionally executed depending on runtime conditions. Immediately after testing a condition(More)
Reconfigurable architectures have become increasingly important in recent years. In this paper we present an approach to the problem of executing 3D graphics interactive applications onto these architectures. The hierarchical trees are usually implemented to reduce the data processed, thereby diminishing the execution time. We have developed a mapping(More)
—Wireless Sensor Networks (WSN 1) have gained worldwide attention in recent years, due to their potential for development of applications in various areas: health, environmental monitoring, control and monitoring processes, etc. Due to the complexity of WSN design, it is necessary to employ design methodologies at a very high level of abstraction which(More)
Development of embedded systems has been growing significantly in the last years, specially, in systems aimed to multicore platforms. As the complexity of these systems grows, high level reliability models are required in order to guarantee correct operation. Currently, there is a lack of design methodologies that consider reliability as an inherent(More)
