Abstract

The Aquarius numeric processor (ANP) is an extended numeric instruction set architecture that is based on the Berkeley programmed logic machine (PLM) and supports integrated symbolic and numeric calculations. This extension expands the existing numeric data type to include 32- and 64-bit integers and single- and double-precision floating-point numbers conforming to the IEEE Standard P754. A class of data structure called numeric arrays has been added to represent matrices and arrays found in most scientific programming languages. Powerful numeric instructions are included to manipulate these novel data types. The authors describe the programming model and the architecture of the ANP. An experimental ANP is currently under construction using TTL (transistor-transistor logic) and ECL (emitter-coupled logic) parts. Simulated performance results indicate that the system will achieve about 10 MFLOPs (millions of floating-point operations) on the Prolog version of some Whetstone and Linpack benchmarks and close to 20 MFLOPS on some matrix operations (all in double precision).<>

为高性能数值计算扩展Prolog架构

Aquarius数字处理器(ANP)是基于Berkeley编程逻辑机(PLM)的扩展数字指令集架构，支持集成符号和数字计算。这个扩展扩展了现有的数字数据类型，包括32位和64位整数以及符合IEEE标准P754的单精度和双精度浮点数。添加了一类称为数值数组的数据结构来表示大多数科学编程语言中的矩阵和数组。包括强大的数字指令来操作这些新颖的数据类型。作者描述了ANP的编程模型和体系结构。目前正在使用TTL(晶体管-晶体管逻辑)和ECL(发射器耦合逻辑)部件构建一个实验性ANP。模拟性能结果表明，该系统在一些Whetstone和Linpack基准测试的Prolog版本上可以实现大约10 MFLOPs(数百万次浮点运算)，在一些矩阵运算(均为双精度)上接近20 MFLOPs。
