Two practical questions in developing an image enhancement computer program are considered: the data structure for the matrix of image samples, and computing the FFT of a large matrix. Experience in ...

He was microcoding a clone of the Control Data Corporation (CDC) 6600 computer. To maximize the performance of the clone, called PUMA, he used a standard trick of writing microcode with many ...

The first computer generally regarded as a supercomputer is the CDC 6600, designed by Seymour Cray and launched in 1964. The venerable CDC 6600, an icon then and now.

The problem of compiling efficient 6600 codes prompted the development of an intermediate language reflecting the structure of the machine, that is more easily manipulated in improving object program ...

This paper explores the feasibility of rapid a- stability analysis of electric power systems containing as many as 60 generators by using Liapunov functions. Many Liapunov functions, approximate ...

The Ferranti Mercury computer was CERN’s first computer. It was installed in Building 2 on 30 June 1958. (Image : CERN) CERN’s first computer, a huge vacuum-tube Ferranti Mercury, was installed in ...
