An Outline of the ICL 2900 Series System Architecture

The system architecture of the ICL 2900 Series is outlined informally. Its central feature, the virtual machine concept, is described and related to virtual storage, segmentation and paging. The procedural approach is then discussed and its implementation by a stack mechanism is described. Further sections outline the protection mechanisms, and the instruction set and related features. Finally the virtual machine approach is related to global system activities.
