Research On The Unified Component Model And Dse For Hybrid Reconfigurable Systems

Hardware and software hybrid reconfigurable systems because of its high-performance, good flexibility and be more and more attention from scholars, but along with the requirement of user increase, a lot of problem come forth. Due to the size of the component library is expanding in the rapid, how to address a specific goals for the reconfigurable computing tasks with exponential growth in the design space quickly search out an optimal component sequence is a very difficult. On the other hand, the form of the existing reconfigurable component model is complex, and the object is single, disadvantageous for the development of hybrid reconfigurable systems. Consider for the features of hybrid reconfigurable systems, is an urgent problem. Relied on a sub-project of the 11th Five-Year plan named "The Researching and Manufacture of Reconfigurable Router Components", this dissertation designs a unified component model to support both software and hardware components, and based on this model, put forward a design space exploration for hybrid reconfigurable systems. The main work is outlined as follows:For the new characteristics of hybrid reconfigurable systems, a Parameterized Reconfigurable Component Model (PRCM) for reconfigurable software/hardware component is designed. The model is based on data-driven mechanism, the component of data processing and data communications separate to make components with loose coupling degree. By standardizing component interface, component functionality and interfaces allow independent, and abstract from the system level hybrid reconfigurable system architecture, software components and hardware components characteristic of parameters, making a uniform component model.Analyzed and summarized the effect of the component function and performance in three basic components assembly methods, given the compound component model based on PRCM parameter calculation method to improve the parameters of reconfigurable component model's versatility in granularity.By analyzing the features of the hardware and software hybrid reconfigurable systems, given the calculation method of the success rate of components'pre-configured, the configuration cost parameters and the data transfer cost parameters of component.A component design space exploration algorithm for hybrid hardware and software reconfigurable systems is proposed. Based on the PRCM, the cost objective function of the reconfigurable computing task performance in hybrid reconfigurable systems was introduced, and on this basis, a reconfigurable component design space fast exploration algorithm based on dynamic programming is proposed, and finally from the theoretical analysis and application tests proved that the algorithm is effective, and achieve the requirement of project...
