过去十五年中硬件工艺的发展,促使计算机系统的体系结构不断改变和计算机应用范围的日益扩大。单个硅集成电路片子的可能最高元件数目提高了三个数量级,相应地降低了计算机 CPU(中央处理机)硬设备每个门的价格和主、辅数据和程序存储器每一位的价格。与此同时,中央处理机和存储器硬设备每个门或每一位的可靠性也提高了大约三个数量级。但是,在中央处理机和存储器的硬设备从固态技术的发展中获得好处的同时,计算机 I/O(输入/输出)和通讯设备的改进相比之下是很缓慢的。致力于应用新工艺和新的系统概念来
The development of hardware technology over the past fifteen years has led to a continuous change in the architecture of computer systems and the growing use of computers. The maximum possible number of components for a single silicon integrated circuit chip is increased by three orders of magnitude, correspondingly reducing the price per gate of the computer CPU hardware and the price per bit of main, auxiliary, and program memory. At the same time, CPUs and memory hard drives have increased the reliability of each door or every bit by about three orders of magnitude. However, improvements in the computer I / O (input / output) and communications equipment are slow compared to the benefits of solid-state technology from hard-core CPUs and memory devices. Committed to applying new processes and new system concepts
