Personal computer with anticipatory memory control signalling

Abstract From the Canadian patent

This invention relates to personal computers and more, particularly to personal computers in which arbitration for control over a data handling bus occurs among a plurality of "master" devices coupled directly to the bus and memory address signals are varied in response to such arbitration. The personal computer system has a high speed local processor data bus, an input/output data bus a, microprocessor coupled directly to the local processor bus volatile memory coupled to the local processor bus for volatile storage of data, and a bus interface controller coupled directly to the local processor bus and directly to the input/output data bus for providing communications between the buses. …
