一、概述随着 LSI、VLSI 及计算机技术的飞跃发展,计算机系统的设计师将面临一系列棘手问题,其中有如下四个共性问题最为突出。1.产品更新换代的周期日益缩短过去十年间,VLSI 技术的迅速发展使得微处理机新产品平均更换周期为2～3年,表1为 Intel 公司微处理机产品的换代史。如何设计新一代的计算机系统而不随 VLSI 技术的进步而见绌,这个问题的本身就是一种技术挑战。
First, an overview With the rapid development of LSI, VLSI and computer technology, computer system designers will face a series of difficult issues, including the following four common problems most prominent. 1. Product replacement cycle is shortened over the past ten years, VLSI technology makes the rapid development of new microprocessor products, the average replacement cycle of 2 to 3 years, Table 1 for the Intel microprocessor product generation history. How to design a new generation of computer systems without dwarfing the progress of VLSI technology is a technical challenge in itself.
