“…MARTE [10] was proposed as a new UML profile to add capabilities to UML for model-driven development of RTES. They also showed in [21] that MARTE UML profile is dedicated to characterize RTE multitasking execution platform via Software Resource Model (SRM) framework. It provides modeling artifacts to describe software execution platform modeling covering main multitasking capabilities such as real-time language libraries and real-time operating systems.…”

Complexity in Distributed Real time Embedded Systems (DRTES) is rising due to richer functionality that is enabled by more powerful hardware. Component-Based Software Engineering (CBSE) and Model Driven Engineering (MDE) help to capture several facets of this complexity. With these two approaches, we build on two main currents in embedded systems research: synchronization and communication.In this paper, we propose a DRTES meta-model to deal with software and hardware aspects of synchronization and communication at a model level. The elements of this meta-model will be used to describe software and hardware specifications and requirements using component as a first class artifact to build such systems. Each component type (generic component) has several instances and multiple views, principally software or hardware one with specific links. The link offers an interface to choose the map between a software and a hardware component at an even greater level using UML profiles derived from DRTES meta-model. This is to allow an automatic exploration at component instance level via Model Driven Engineering. As a proof of concept we examine a test case that has software and hardware synchronization and communication requirements: a GPS.

“…The Adaptive Unsharper Image Filter is a special filter that enhances the contrast of an input color image, as described in Thomas et al [2007]. This algorithm uses an adaptive filter that controls the contribution of the sharpening path in such a way that contrast enhancement occurs in high detail areas and -read im reads the images from the input stream; -split im divides the single frame in the three separate color components (Red, Green, and Blue); -unsharp im is a battery of three unsharper filters, one for each color component; -union im reassembles the three components into a single-color image frame; -display im adapts the internal image representation to the external displaying engine.…”

This article summarizes our effort, since 2004 up to the present time, for improving the current industrial Systems-on-Chip and Embedded Systems design by joining the capabilities of the unified modeling language (UML) and SystemC/C programming languages to operate at system-level. The proposed approach exploits the OMG model-driven architecture-a framework for Model-driven Engineering-capabilities of reducing abstract, coarse-grained and platform-independent system models to fine-grained and platform-specific models. We first defined a design methodology and a development flow for the hardware, based on a SystemC UML profile and encompassing different levels of abstraction. We then included a multithread C UML profile for modelling software applications. Both SystemC/C profiles are consistent sets of modelling constructs designed to lift the programming features (both structural and behavioral) of the two coding languages to the UML modeling level. The new codesign flow is supported by an environment, which allows system modeling at higher abstraction levels (from a functional executable level to a register transfer level) and supports automatic code-generation/back-annotation from/to UML models.
