八十年代中期有可能把一百万个器件(晶体管或有源的MOS栅极)做在单个硅片上。本文先回顾一下硅片集成电路的总的发展趋势,并分析正在兴起的VLSI电路的设计所受的限制,然后讨论当代计算机希望具有的体系结构的特点,并研究它对实现大面积集成电路的影响。据此推荐的处理机设计具有下述优点,如在一个芯片上组成存储体系,用来增强平行执行能力的多个同样的高速缓存,支持复杂的数据结构和高级语言,具有可塑性的指令集以及通讯硬件。可以肯定,能在下一代计算机系统中生存的模块式的积木块将是做在单个硅片上的独立的计算机。文中给出了将一百万个晶体管用于各种功能块时的一个试验性的分配,它采用的是着眼于存储体系的设计方法。
In the mid-eighties it was possible to make a million devices (transistors or active MOS gates) on a single piece of silicon. This paper first reviews the overall development trend of silicon integrated circuits and analyzes the limitations of the emerging VLSI circuit design. Then it discusses the characteristics of the contemporary computer architecture that it hopes to have, and studies how it can be used to implement large area integrated circuits influences. The processor design recommended here has the following advantages, such as multiple identical caches that compose a storage system on a single chip, multiple parallel execution capabilities, complex data structures and high-level languages, a malleable instruction set, and Communication hardware. To be sure, the modular blocks that will survive the next generation of computer systems will be stand alone computers on a single silicon chip. The paper presents a tentative allocation of one million transistors to various functional blocks, using a design approach that focuses on the storage system.
