Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
116 words
A controller having a computer interface between a proprietary bus and at least one local area network (LAN) system for coupling a plurality of different types of LANs to said controller, said proprietary bus comprising: (a) a microprocessor bus having coupled to it at least a first microprocessor (µP); (b) a direct memory (DMA) bus having coupled to it at least a first memory, said µP bus being coupled to said DMA bus by first transmit/receive means for transmitting/receiving information between said µP bus and said DMA bus; and, (c) an adapter bus coupled to said DMA bus, and including an adapter interface for coupling said proprietary bus to said plurality of different types of LANs.
Claim 2
Dependent Claim
116 words
A controller having a computer interface between a proprietary bus and at least one local area network (LAN) system for coupling a plurality of different types of LANs to said controller, said proprietary bus comprising: (a) a microprocessor bus having coupled to it at least a first microprocessor (µP); (b) a direct memory (DMA) bus having coupled to it at least a first memory, said µP bus being coupled to said DMA bus by first transmit/receive means for transmitting/receiving information between said µP bus and said DMA bus; and, (c) an adapter bus coupled to said DMA bus, and including an adapter interface for coupling said proprietary bus to said plurality of different types of LANs.
Claim 3
Dependent Claim
25 words
The controller as recited in Claim 1 wherein said adapter interface includes at least one connector for connecting said adapter bus to said DMA bus.
Claim 4
Dependent Claim

Claim 7
Dependent Claim
23 words
The controller as recited in Claim 2 wherein said adapter interface includes first transceivers for coupling said DMA bus to said adapter bus.
Claim 8
Dependent Claim
24 words

Claim 9
Dependent Claim
22 words
The controller as recited in Claim 8 wherein said µP bus further comprises a µP control signal bus and aµP data/address bus.
Claim 10
Dependent Claim
23 words
The controller as recited in Claim 9 including an erasable programmable read only memory (EPROM) coupled to said µP data and address bus.
Claim 11
Dependent Claim
19 words
The controller as recited in Claim 10 including a timing controller coupled to said µP data and address bus.
