【摘要】：隨著超大規(guī)模集成電路工藝技術(shù)的高速發(fā)展，器件尺寸變得越來(lái)越小，在單芯片上的集成的模塊也越來(lái)越多，系統(tǒng)的功能也越來(lái)越復(fù)雜。在昂貴的芯片設(shè)計(jì)和制造成本，以及越來(lái)越短的開(kāi)發(fā)周期的壓力下，怎么能設(shè)計(jì)出成本和性能都符合要求的系統(tǒng)就成為系統(tǒng)設(shè)計(jì)研究領(lǐng)域的棘手課題之一。在這樣的背景下，軟硬件協(xié)同設(shè)計(jì)技術(shù)引起了研究人員的廣泛關(guān)注。 本文從嵌入式系統(tǒng)出發(fā)，試圖尋找目前嵌入式系統(tǒng)設(shè)計(jì)存在的問(wèn)題和缺點(diǎn)；通過(guò)對(duì)幾種較有影響的軟硬件協(xié)同設(shè)計(jì)方法Cosyma、POLIS、Cool等的研究，討論了這幾種方法的優(yōu)點(diǎn)和存在的問(wèn)題。作為軟硬件協(xié)同設(shè)計(jì)的重要組成部分，在軟硬件劃分領(lǐng)域，，過(guò)去己經(jīng)有不少大學(xué)和機(jī)構(gòu)進(jìn)行了許多有意義的探索，有些軟硬件劃分方法己經(jīng)在實(shí)用方面獲得了一定的成功，有效的改善了系統(tǒng)的結(jié)構(gòu)合理性，縮短了開(kāi)發(fā)周期。本文在前人研究的基礎(chǔ)上提出了一種基于UML的軟硬件劃分建模方法。在UML軟硬件劃分建模方法中，采用用例驅(qū)動(dòng)技術(shù)，并針對(duì)系統(tǒng)的非功能性屬性作了部分?jǐn)U展，增加了對(duì)于系統(tǒng)軟硬件劃分所需的部分約束的要求；在此基礎(chǔ)上，提出了一種從UML圖到任務(wù)圖的轉(zhuǎn)化方法；通過(guò)Diane+任務(wù)模型對(duì)系統(tǒng)進(jìn)行功能劃分。在本文的最后，基于本文所提出的方法實(shí)現(xiàn)了一個(gè)簡(jiǎn)化的具有基本功能的衛(wèi)星模型的建模，演示了基于UML的嵌入式平臺(tái)軟硬件協(xié)同設(shè)計(jì)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.
