视图

Formerly,a sub-select or view could not be optimized very well if it appearedwithin the nullable side of an outer join and contained non-strictexpressions in its result list.

以前，如果外连接可接受空值的那一边是子查询或者视图，并且返回列表里包含不严格的表达式，总是优化的不太好。

Firstly, the basic concept of software/hardware co-design and the present research situation worldwide is introduced, the techniques are also discussed separately in the thesis, which is in the system description stage, system architecture design stage, hardware/software design and implementation stage. Secondly, combined with three representative methods of hardware/software co-design systems: POLIS、VULCAN and CORSAIR, the main steps of co-design are studied and analyzed including system description, hardware/software partitioning and hardware/software implementation-synthesis, and some new ideas are given here. Thirdly, UML and modeling technology of embedded systems using UML are described clearly, a handheld terminals is a good example for this, furthermore, the algorithm of how to convert the UML diagram into SystemC codes is mainly concerned on in this thesis. Fourthly, the basic concept of SystemC is described, and the SystemC Modeling platform and simulation mechanism are analyzed, software/hardware co-design methods using SystemC are discussed. Finally, by applying co-design ideas using UML and SystemC, software/hardware co-design system using UML and SystemC is preparatorily implemented, which is to establish a development environment for designing embedded system.

本文首先介绍了软硬件协同设计的基本概念和国内外研究现状，并分别论述了系统描述阶段的技术、系统结构设计阶段的技术、软硬件设计与实现阶段的技术；接着结合POLIS、VULCAN和CORSAIR 三种有代表性的软硬件协同设计方法，对系统描述、软硬件划分、软硬件实现综合等几个主要设计步骤进行了研究与分析，并提出了新的方法和思路；然后详细介绍了UML及基于UML的嵌入式系统建模技术，并以嵌入式手持终端系统来举例说明，重点研究将UML的视图转换成SystemC代码的算法；其次介绍了SystemC的基本概念，分析了SystemC 的建模平台和仿真机制，并对基于SystemC 的软硬件协同设计方法进行探讨；最后应用基于UML和SystemC的软硬件协同设计的设计思路，初步实现基于UML和SystemC的软硬件协同设计的设计系统，目的是建立一个用于嵌入式系统设计的开发环境。
