Networks-on-chip (NoCs) are communication architecture alternatives for complex Systems-on-Chip (SoCs) designs, due to their high scalability and bandwidth. In this paper, we consider a heterogeneous NoC as an alternative to match performance and energy requirements for dedicated applications. By employing an optimized mix of different routers, a(More)
This work analyzes, the mapping of applications onto generic regular Networks-on-Chip (NoCs). Cores must be placed considering communication requirements so as to minimize the overall application execution time and energy consumption. We expand previous mapping strategies by taking into consideration the dynamic behavior of the target application and thus(More)
Complex applications implemented as Systems on Chip (SoCs) demand extensive use of system level modeling and validation. Their implementation gathers a large number of complex IP cores and advanced interconnection schemes, such as hierarchical bus architectures or networks on chip (NoCs).

– Task mapping is an important issue in MPSoC design. Most recent mapping algorithms perform them at design time, an approach known as static mapping. onetheless, applications running in MPSoCs may execute a varying number of simultaneous tasks. In some cases, applications may be defined only after system design, enforcing a scenario that requires the use(More)
