本文介绍了美国陆军弹道导弹防御高级技术中心(BMDATC)为研究弹道导弹防御系统而研制的平行单元处理集合体(PEPE)的体系结构。该计算机以一台 CDC7600计算机为主机,周围有288个单元,每个单元包括三台处理机,分别用作运算部件、相关部件和相联输出部件,公用一个数据存储器。所有单元的这三个部件各由控制机架中的一个控制器驱动。文中以相控阵雷达为例,简要地叙述了弹道导弹防御系统对数据处理的要求,由此确定 PEPE 的体系结构是平行处理和相联工作方式的。文中对 PEPE 的设计思想、各部分的组成和工作情况作了比较细致的介绍,也扼要地介绍了其结构和配套软件的特点,同其它类型的平行阵列处理机作了比较。介绍了 PEPE 在弹道导弹防御系统及解流体力学问题中的应用。最后提出了 PEPE 体系结构的改进方案,主要是信号分配系统的简化。
This article describes the architecture of the Parallel Unit Processing Aggregation (PEPE) developed by the BMDATC to study ballistic missile defense systems. The computer is hosted on a CDC7600 computer, surrounded by 288 cells. Each cell includes three processors, each serving as an arithmetic unit, associated unit and associated output unit, sharing a single data memory. The three components of all units are each driven by a controller in the control rack. In this paper, the phased array radar is taken as an example to briefly describe the data processing requirements of the ballistic missile defense system. It is determined that the PEPE architecture is parallel processing and associated working methods. In this paper, the design idea of PEPE, the composition and work of each part are introduced in detail, and its structure and the characteristics of the software are also briefly introduced. Compared with other types of parallel array processors. The application of PEPE in ballistic missile defense system and solution to fluid mechanics problems is introduced. Finally, an improved scheme of PEPE architecture is proposed, mainly the simplification of signal distribution system.
