In general, complex embedded systems rely on specialized operating system kernels. However, the operating system usage may introduce significant time overhead, which may affect the tasks' deadline in embedded hard real-time systems. In addition, hardware requirements (e.g. memory) are usually increased.As an alternative, this paper presents a software(More)
This paper presents a methodology for mapping the Live Sequence Chart (LSC) language to an equivalent Coloured Petri Net (CPN) model as an approach for analysis and verification of embedded systems' properties. LSC is a language for system specification, allowing one to specify what should happen for all execution of the system as well as the modeling of(More)
In recent years, discrete control systems play an important role in the development and advancement of modern civilization and technology. Practically every aspect of our life is affected by some type of control systems. This kind of system maybe classified as an embedded real-time system and requires rigorous methodologies to develop the software that is(More)
This paper describes an agile development methodology which combines agile principles with organizational patterns and adapts them to build embedded real-time systems focusing on the system's constraints. The hard-ware/software partitioning and platform-based design are used in the proposed methodology to support the embedded system designer meet the(More)
In recent days, the amount of functions has increased significantly in embedded products so that systems development methodologies play an important role to ensure the product's quality, cost, and time. Furthermore, this complexity coupled with constantly evolving specifications, has led to propose a semiformal development methodology to support the(More)
