项目摘要

The objective of this research is that we should develop a specific computer which performs geometrical-figure processing very rapidly. The geometrical-figure processing is the primitive function in the current LSI design. It comprises logical, topological and geometrical operations and also area/length calculation.This research aimed to dissolve the bottle-neck in the current LSI design process by that specific computer.The results of this research are as follows1.Acceleration of parallel processing in LSI design rule check (DRC)2.Development of a computer system specific to LSI DRC3.A method of DRC by functional partitioning.4.Development of a functional memory type parallel processor.We constructed a computer system to evaluate the above results. A host computer which controls all processor elements (called workers) is a standard engineering work station using 68040 processors. We developed four brand-new workers. The worker performs data input and output simultaneously using two-port memory modules. The DRC processing unit in the worker is a single-board computer which comprises a CPU called M32/100. And also we developed software packages which control the system and performs DRC.This system with two workers performs DRC twice faster than that with a single worker.

这项研究的目的是我们应该开发一种能够非常快速地执行几何图形处理的特定计算机。几何图形处理是当前LSI设计中的基本功能。它包括逻辑、拓扑和几何运算以及面积/长度计算。本研究旨在通过特定计算机解决当前LSI设计过程中的瓶颈。研究结果如下1.LSI设计规则检查(DRC)并行处理的加速2.LSI DRC专用计算机系统的开发3.基于功能分区的DRC方法4.功能存储器的开发型并行处理器。我们构建了一个计算机系统来评估上述结果。控制所有处理器元件（称为工作器）的主机是使用 68040 处理器的标准工程工作站。我们培养了四名全新的工人。工作器使用两端口内存模块同时执行数据输入和输出。 Worker 中的 DRC 处理单元是一个单板计算机，包含一个名为 M32/100 的 CPU。我们还开发了控制系统和执行DRC的软件包。这个有两个worker的系统执行DRC的速度是单个worker的两倍。
