“…A considerable amount of research in the area of visual environments have been carried out aimed at the development of software able to reduce the difficulties found in the development of parallel systems. This effort resulted in user-friendly tools such as TEV [8], PVMGraph [9], Millipede [10], TRAPPER [11] and GRADE [12,13]. Even though there are several differences between these environments, they all focus on making the program development easier, providing graphical representations to map paradigms or libraries designed for the development of parallel systems.…”

The concepts involved in the programming process of multicore systems have been quite well known for decades. The problem is to produce it in a form as easy as sequential programming. This new trend will change the way we think about the whole development process. We will show that it is possible to develop a multicore embedded system application using existing tools and the model-driven development process proposed. To do this, two tools will be used: VisualRTXC (available at www.quadrosbrasil.com.br) for generating the multithread communication/synchronization structures and a performance tool called TAU (available at

“…Back-annotation was not provided, however, and there was no investigation into the speed of analysis. Another prototype for an integrated development environment came from Ribeiro et al [52]. The aim was to provide continuity in a real-time software project through the phases of implementation, debugging, and testing.…”

Abstract-For hard real-time systems, static code analysis is needed to derive a safe bound on the worst-case execution time (WCET). Virtually all prior work has focused on the accuracy of WCET analysis without regard to the speed of analysis. The resulting algorithms are often too slow to be integrated into the development cycle, requiring WCET analysis to be postponed until a final verification phase.In this paper we propose interactive WCET analysis as a new method to provide near-instantaneous WCET feedback to the developer during software programming. We show that interactive WCET analysis is feasible using tree-based WCET calculation. The feedback is realized with a plugin for the Java editor jEdit, where the WCET values are back-annotated to the Java source at the statement level. Comparison of this treebased approach with the implicit path enumeration technique (IPET) shows that tree-based analysis scales better with respect to program size and gives similar WCET values.

“…In order to offer support for the development of parallel applications with Virtuoso, a tool Visual Environment for the Development of Real-Time Parallel Programs [8,10] was developed at the Department of Computer Science at UFSCar. The first version of the tool is available for download from http://www.dc.ufscar.br/wtev and was released as Teaching Environment for Virtuoso (TEV).…”
