Analysis and Improvement of Task Schedulability in Hardware/software Codesign Analysis and Improvement of Task Schedulability in Hardware/software Codesign
Many real-time systems have timing requirements that are diicult to fulll if the system is implemented by software running on a microprocessor. One way to remedy this problem is to implement the most time-critical parts in application-speciic integrated circuits instead. Hardware/software codesign aims at providing support for the designer of such a heterogeneously implemented system, and espec...

Based on the methodology for the development of communication systems, a framework for early performance evaluation and hardware/software codesign of such systems is presented. We describe how performance requirements can be formulated in a formal way during the analysis phase of a project and how these requirements are used by the synthesis tools for hardware/software codesign during the desig...
متن کاملHardware/software Partitioning of Real-time Systems
Many high-performance embedded real-time systems are today implemented heterogeneously, with some parts of the functionality in hardware and others in software. In this paper, we discuss how hardware/software codesign techniques can be used to improve the design of such systems, and we focus on hardware/software partitioning and its relation to other important design activities, such as system ...
متن کاملAn Evolutionary Approach to Hardware/ Software Partitioning
In this paper, we present an approach to hardware/software codesign of real-time embedded systems. Two of the di culties associated with codesign are handling tradeo s among multiple attributes and exploring a large design space. We use a combination of techniques from the evolutionary computation and utility theory elds to address these problem areas. A real-time microcontroller-based design e...
متن کاملEnhancing Schedulability of Hard Real-Time Systems through Codesign
This paper deals with the problem of hardware-software codesign of hard real-time systems. For a given task set, we perform an exact schedulability test to determine whether the task set is schedulable or not. When there is a task that cannot meet the deadline, we compute the amount of time by which the deadline is missed. Then we determine which tasks should reduce their execution time to comp...
