The design of high performance multimedia systems in a short time force us to use IP's blocks in many designs. However, their correct integration in a design implies more complex verification problems. In this paper, we present a C++/SystemC based simulation flow at multiple levels of abstraction. Our approach is to use SystemC to describe both application(More)

The complexity of multimedia applications in terms of intensity of computation and heterogeneity of treated data led the designers to embark them on multiprocessor systems on chip. The complexity of these systems on one hand and the expectations of the consumers on the other hand complicate the designers job to conceive and supply strong and successful(More)
The flexible job shop problem (FJSP) is a generalization of the classical job shop scheduling problem. The meta-heuristic particles swarm optimization (PSO) is well suited to solve the FJSP but it might be time consuming specially on monocore platforms. In this paper, we propose some PSO-FJSP variants that aim to improve the performance in term of CPU time.
Codesign choices of a system differ in terms of different hardware/software partitions, different types of architectural components, different communication architectures, etc. This paper presents an analytic method to estimate the gain on a system throughput when a software task is selected to be moved to hardware during the codesign process. The method is(More)
