There are several approaches to the hardware/software design in embedded systems, ranging from the traditional sequential methods which focus on the determination of the hardware architecture prior to software design, to newer object-oriented approaches that attempt to apply software engineering methods to hardware design without a systematic process. This paper discusses a structured object-oriented methodology for the integrated co-analysis and co-design of hardware/software systems using an extended high order object-oriented modeling technique (HOOMT). This methodology offers a uniform method for hardware and software developers to jointly develop the specifications for and partitioning of the hardware and software components of a …

Component-based software development (CBSD) offers many advantages like reduced product time to market, reduced complexity and cost etc. Despite these advantages its wide scale utilization in developing security critical systems is currently hampered because of lack, of suitable design techniques to efficiently manage the complete system security concerns in the development process. The use of commercial of the shelf (COTS) components can introduce various security and reliability risks in the system. In this paper we propose a methodology for efficient management of all the system security concerns involved in the design of component based systems. Our methodology is based on …

Software metrics can be used to objectively quantify the quality of software components and systems, alleviating quality and risk concerns and raising assurance in component-based systems. In this paper, we present a graph-based model for component-based software development. We assume that a number of components have been characterized in terms of non-functional metrics of importance to the software system being developed, and that the interfaces connecting various components have been similarly characterized. The emphasis of this work is on cost and quality of the system under development, and reaching an acceptable compromise between the two.
