【摘要】：随着超大规模集成电路工艺技术的高速发展，器件尺寸变得越来越小，在单芯片上的集成的模块也越来越多，系统的功能也越来越复杂。在昂贵的芯片设计和制造成本，以及越来越短的开发周期的压力下，怎么能设计出成本和性能都符合要求的系统就成为系统设计研究领域的棘手课题之一。在这样的背景下，软硬件协同设计技术引起了研究人员的广泛关注。本文从嵌入式系统出发，试图寻找目前嵌入式系统设计存在的问题和缺点；通过对几种较有影响的软硬件协同设计方法Cosyma、POLIS、Cool等的研究，讨论了这几种方法的优点和存在的问题。作为软硬件协同设计的重要组成部分，在软硬件划分领域，，过去己经有不少大学和机构进行了许多有意义的探索，有些软硬件划分方法己经在实用方面获得了一定的成功，有效的改善了系统的结构合理性，缩短了开发周期。本文在前人研究的基础上提出了一种基于UML的软硬件划分建模方法。在UML软硬件划分建模方法中，采用用例驱动技术，并针对系统的非功能性属性作了部分扩展，增加了对于系统软硬件划分所需的部分约束的要求；在此基础上，提出了一种从UML图到任务图的转化方法；通过Diane+任务模型对系统进行功能划分。在本文的最后，基于本文所提出的方法实现了一个简化的具有基本功能的卫星模型的建模，演示了基于UML的嵌入式平台软硬件协同设计建模的基本流程。
[Abstract]:With the rapid development of VLSI technology, the device size becomes smaller and smaller, more and more modules are integrated on a single chip, and the functions of the system become more and more complex. Under the pressure of shorter and shorter development cycle, how to design a system that meets the requirements of both cost and performance becomes one of the thorny topics in the field of system design. Hardware and software co-design technology has attracted wide attention of researchers. Based on the embedded system, this paper tries to find out the problems and shortcomings in the embedded system design at present, and through the research of several influential hardware and software co-design methods, such as Cosyma / POLISCool, etc. The advantages and problems of these methods are discussed. As an important part of hardware and software co-design, in the field of software and hardware partition, many universities and institutions have carried out many meaningful explorations in the past. Some software and hardware partitioning methods have achieved some success in practical aspects, and have effectively improved the structural rationality of the system. In this paper, a software / hardware partitioning modeling method based on UML is proposed based on previous researches. In UML software / hardware partitioning modeling method, use case driven technology is used. The non-functional attributes of the system are partially extended, and the requirements of some constraints required for the partition of the system's hardware and software are added. On this basis, a transformation method from the UML diagram to the task diagram is proposed. In the end of this paper, a simplified satellite model with basic functions is built based on the method proposed in this paper. The basic process of hardware / software co-design modeling of embedded platform based on UML is demonstrated.
