| Research Abstract |
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 follows
1.Acceleration of parallel processing in LSI design rule check (DRC)
2.Development of a computer system specific to LSI DRC
3.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.
