参数化的可重构系统抽象模型

Parameterized abstract model for reconfigurable systems

为使可重构系统的设计空间搜索方法不依赖于任何具体的可重构结构,总结了描述可重构系统的结构特征参数,提出了可重构系统结构的层次-参数模型.该模型是一个层次化结构的通用模型,逐层向下由顶层结构、块结构、单元结构和功能结构4部分组成,每种结构代表一个层次.通过将各种参数代入模型中的各个描述项,可以描述影响可重构系统性能的结构特征.利用该模型分别对2种典型的动态和静态可重构系统进行了描述,应用结果表明,系统的结构特征均可通过自顶向下4层结构描述清楚,体现了模型良好的扩展性和通用性.

Through summarizing chitecture model, e.g. hierarchi general cal-paramet featur erized mapping and design space exploration method ind This ture, level. general-purpose and hierarchical me block structure, element structure del consis es of reconfigurable architectures, a reconfigurable armodel, was presented in order to make the algorithm ependent on any concrete reconfigurable architecture. ts of 4 parts. From top to bottom they are top strucand functional structure, where each part represents a structure With the corresponding parameters set into the description items, this model can describe the hierar chical architecture of target system, which is crucial to performance. The proposed parameterized model was applied to two domain representative components, in which one is dynamic system and the other is static one. The results showed that both these two cases can be described with this four-level model from top to down, whieh shows the good extensibility and universality of this modeling method.
