新发布的IBM System/360的体系结构 * 具有四项创新：1.一种存储方法，它允许并利用极大的容量、分级的速度、用于微程序控制的只读存储器、灵活的存储保护和简单的程序再定位。2.一种输入/输出系统，它提供了新的并行操作程度，兼容的通道操作，接近5，000，000字符/秒的数据速率，硬件和软件的综合设计，一种新的低成本、多通道组件共享主机硬件，新的设备状态信息预测，以及中央处理单元和输入/输出设备之间的标准通道接口。3.一个真正的通用机器组织，提供新的监控设施，强大的逻辑处理操作和各种数据格式。4.严格的向上和向下机器语言兼容性超过一行的六个型号，性能范围系数为50。
本文详细讨论了设计的目标和基本原理的主要特点的架构。强调的是需要各种规模的中央处理器之间的兼容性和商业，科学，实时和逻辑信息处理的相互冲突的需求所提出的问题。该体系结构的表格式总结见附录。
The architecture* of the newly announced IBM System/360 features four innovations: 1. An approach to storage which permits and exploits very large capacities, hierarchies of speeds, read-only storage for microprogram control, flexible storage protection, and simple program relocation. 2. A input/output system offering new degrees of concurrent operation, compatible channel operation, data rates approaching 5,000,000 characters/second, integrated design of hardware and software, a new low-cost, multiple-channel package sharing main-frame hardware, new previsions for device status information, and a standard channel interface between central processing unit and input/output devices. 3. A truly general-purpose machine organization offering new supervisory facilities, powerful logical processing operations, and a wide variety of data formats. 4. Strict upward and downward machine-language compatibility over a line of six models having a performance range factor of 50.
This paper discusses in detail the objectives of the design and the rationale for the main features of the architecture. Emphasis is given to the problems raised by the need for compatibility among central processing units of various size and by the conflicting demands of commercial, scientific, real-time, and logical information processing. A tabular summary of the architecture is shown in the Appendices.
