Lan Controller Having Split Bus Design

View page
US Patent:
47712864, Sep 13, 1988
Filed:
Jul 28, 1986
Appl. No.:
6/891077
Inventors:
Leonard E. Niessen - Framingham MA
Allen C. Hirtle - Littleton MA
Edward Beauchemin - Marlboro MA
Assignee:
Honeywell Bull Inc. - Minneapolis MN
International Classification:
H04Q 1100
H04J 300
US Classification:
340825520
Abstract:
A split bus architecture which separates the processor/processors and the procedure memory coupled to a microprocessor (. mu. P) bus from all direct memory access (DMA) devices coupled to a DMA bus. A coupler mechanism provides bus isolation of the microprocessor bus from the DMA bus and permits the processor to access devices on the DMA side when addressed. This separation allows data transfers to proceed on one side of the bus without interfereing with software execution on the other side of the bus.
