计算机技术目前已出现了一些脱离传统模式的变化,正从以设备开发为主转向以知识发展为主,因而促成了计算机产业向知识产业转变的趋势。就计算机系统本身而言,综合设计已成为现时的发展方向。硬件和软件的设计、功能模拟、验证以及制造、检测等工作的综合进行,大大缩短了新产品周期。其中每一过程的自动化、工程化、标准化,也显著降低了成本,提高了产品性能与可靠性,使产品有很高的性能价格比。这种集成系 At present, computer technology has emerged some changes from the traditional model. It is shifting from the development of equipment to the development of knowledge, which has led to the trend of computer industry changing to knowledge industry. As far as the computer system itself is concerned, integrated design has become the current direction of development. Hardware and software design, functional simulation, verification and manufacturing, testing and other work carried out, greatly shortening the new product cycle. Each process of automation, engineering, standardization, but also significantly reduce costs and improve product performance and reliability, so that products have a high cost performance.
