Recent embedded systems and SOCs design is confronted with the problem of the so-called productivity gap. In order to cope with this problem, authors emphasize on using UML as a system level language, so higher level of abstraction is achieved. However UML in its current form has not yet achieved the maturity necessary to enable its efficient use within(More)
In this paper, we would like to present a new UML-based methodology for embedded applications design. Our approach starts from a pure sequential object paradigm model from which a task level model is extracted. The latter allows designer to expose all parallelism forms such as task parallelism, data parallelism, pipelining, while making control and(More)
In this paper, we present our approach for automatic SystemC code generation from UML models at early stages of Systems On Chip (SOC) design. A particularity of our proposed approach is the fact that SystemC code generation process is performed through two levels of abstraction. In the first level, we use UML hierarchic sequence diagrams to generate a(More)
— In today's scenario, high performance computing is needed to solve the complex scientific problems. In this regards the Multi-core technology is one of the major technologies. Intel's Dual Core processors improve the performance of applications by executing multiple programs at a time. The objective of the present paper is to evaluate the performance of(More)
Embedded multimedia systems with multi-application scenarios increase the number and computational power of processing elements. To satisfy this growing demand, a network on chip is used due to lower message latency, better scalability and more reliable performance predictability. Today the focus is not on the implementation of one single application on the(More)
—In this work, we are concerned with automatic synthesis and formal verification of interfaces between incompatible soft intellectual properties (IPs) for System On Chip (SOC) design. IPs Structural and dynamic aspects are modeled via UML2.x diagrams such as structural, timing and Statecharts diagrams. From these diagrams, interfaces are generated(More)
