摘　　要：针对现有可重构模型的不足,提出一种面向任务的支持组合设计的可重构计算模型系统.以生产者-消费者数据类型显式描述任务间通讯关系,并形式化描述任务的设计和运行时特征,提供组合设计规则,能够自动生成合成任务的各项属性,方便了应用系统的构建和性能评估.基于该模型可进行快速设计空间搜索,寻找最佳的系统设计方案.最后给出该模型的两种不同应用示例.After investigating the inability of the current reconfigurable computing model, a task-oriented model featuring composition design was proposed. The model took the data type to explicitly describe the communication topology among tasks. It recorded the task＇s design-time and run-time characteristics formally, and automatically calculated the composite task＇s attributes according to the generation rule. This helped application system construction and performance evaluation. It can be used as a basis for fast design space exploration in search of an optimal design solution for a specific system. Finally, examples of two application cases of the presented model were given .
