一个计算机系统总是包含软件和硬件两大部分。软件和硬件的界面特性就是这个计算机系统的体系结构。对软件的长期投资使计算机的体系结构具有相当的稳定性。这种稳定性要求新设计的计算机必须与已有的某种计算机兼容。从这个意义上,世界上,当代的计算机硬件设计大多采用兼容设计。由于我国没有建立自主的软件基础,没有形成稳定的体系结构,硬件设计被迫采用国外“优选”的体系结构,其设计方法也属于兼容设计。但是由于这种特殊的环境使我们的兼容设计方法不同一般。本文总结在国内小型计算机领域内我们走过的兼容设计道路,讨论了它所面临的由VLSI所提出的新的挑战,探索了可能的对策。 相似文献

因为Windows Vista中很多系统底层的东西发生了改变,很多程序在安装和使用上可能会遇到问题。这时候可以考虑使用Windows Vista的兼容模式。除了杀毒软件、硬件驱动等这类工作在系统底层的软件外,绝大多数一般软件都可以借助该模式正常运行在Windows Vista下。 相似文献

基于Proteus的硬件在回路仿真 总被引:3,自引:0,他引:3
软、硬件的并行开发方法可以加快设计进程,但在系统整合时常常出现诸如软、硬件不兼容等很多问题,而硬件在回路仿真能有效解决这些问题,它的最大特点是将软件仿真与实际硬件紧密联系起来,采用该技术可以在开发周期初完成嵌入式系统的仿真.介绍了一种基于Proteus的硬件在线回路仿真技术,为嵌入式产品的开发提出了新的思路.并通过"电子警察"这一具体开发实例来说明基于Proteus的硬件在回路仿真技术在嵌入式产品开发中的意义.实践证明,基于Proteus的硬件在回路仿真可以大大缩短产品的开发周期和降低开发成本. 相似文献

一、前言仿真培训系统的硬件是软件运行的支持环境,其结构及功能和仿真软件的要求密切相关。必须使硬件的设计达到标准化、系列化、组装化及不同型号硬件的兼容特性,才能便于推广普及、便于维修、便于备品备件的提供、节省投资。更重要的是便于实现软件的互换性和通用性。换言之,只有首先实现了硬件的标准化,才能真正实现仿真培训软件的标准化。 相似文献

The design of mechatronic systems is based on the integration of several disciplines, such as mechanical, electrical and software engineering. How to achieve an integrated multidisciplinary design during the development process of mechatronic systems has attracted the attention of both academia and industry. However, solutions which can fully solve this problem have not been proposed by now. The concept of multidisciplinary interface represents the logical or physical relationship integrating the components of the mechatronic system or the components with their environment. As the design of mechatronic systems is a multidisciplinary work, the multidisciplinary interface model can be considered as one of the most effective supports to aid designers for achieving the integrated multidisciplinary design during the development process. The paper presents a multidisciplinary interface model for design of mechatronic systems in order to enable the multidisciplinary integration among design team members from different disciplines. On the one hand, the proposed model ensures the consistency of interface defined by the designers. On the other hand, it helps the designers to guarantee the different components integrate correctly. The interface model including three concepts: classification, data model and compatibility rules. The multidisciplinary interface model is implemented by a case study based on a 3D measurement system. 相似文献

Stimulus–response compatibility has been a staple of human factors since the early 1950s, when it was established by Paul Fitts, one of the founders of human factors. The importance of maintaining spatial compatibility is indicated in textbooks, but maintaining compatibility in design is not a simple task, because there are many factors that need to be taken into consideration. This article focuses on spatial compatibility and the more recently investigated affective compatibility, highlighting their implications for human–computer interaction. An overview of other cognitive compatibility principles and examples of their use in human–computer interaction is also provided. Advanced technology has increased the need for systematic consideration of compatibility phenomena in user interface design, and the article ends with a summary of key points for designers. 相似文献

The Itanium processor is the first implementation of the IA-64 instruction set architecture (ISA). The design team optimized the processor to meet a wide range of requirements: high performance on Internet servers and workstations, support for 64-bit addressing, reliability for mission-critical applications, full IA-32 instruction set compatibility in hardware, and scalability across a range of operating systems and platforms. The processor employs EPIC (explicitly parallel instruction computing) design concepts for a tighter coupling between hardware and software. In this design style the hardware-software interface lets the software exploit all available compilation time information and efficiently deliver this information to the hardware. It addresses several fundamental performance bottlenecks in modern computers, such as memory latency, memory address disambiguation, and control flow dependencies 相似文献

The goal of the GUARDS project is to design and develop a generic fault-tolerant computer architecture that can be built from
predefined standardised components. The architecture favours the use of commercial off-the-shelf (COTS) hardware and software
components. However, the assessment and selection of COTS components is a non-trivial task as it requires balancing a myriad
of requirements from end-users and the preliminary architecture design. In this paper, we present the requirements and assessment
criteria for a specific COTS software component, the operating system kernel. As an interface specification constitutes a
major compatibility criterion for the selection of COTS components in GUARDS, a particular emphasis is placed on operating
system conformance to the POSIX 1003.1 standard. We discuss the general lessons learned from the assessment process and raise
a number of questions relevant to the assessment of any COTS software component. 相似文献
