COMPUTER ORGANIZATION: Architecture
Vojin G. Oklobdzija · 1999
The term Computer Architecture was first defined in paper by Amdahl, Blaauw and Brooks of IBM Corporation announcing IBM System/360 computer family on April 7, 1964. On that day IBM Corporation introduced, in words of IBM spokesman, the most important product announcement that this corporation has made in its history. There were six models introduced originally, ranging in performance from 25 to 1. Six years later this performance range was increased to about 200 to 1. This was key feature which prompted IBM's effort to design an architecture for a new line of computers that are to be code compatible with each other. The recognition that architecture and implementation could be separated and that one need not imply other led to establishment of a common System/360 machine architecture implemented in range of models.
