Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
159 words
A data processing system comprising: (a) a first plurality of elements coupled by means of a first common bus to transfer information between said first plurality of elements, said first plurality of elements comprising at least a first, second and third unit wherein said first unit is a first resource shareable by at least the second and third units; (b) a second plurality of elements coupled by means of a second common bus to transfer information between said second plurality of elements, said second plurality of elements comprising at least a fourth, fifth and sixth unit wherein said fourth unit is a second resource shareable by at least the fifth and sixth units, and wherein said second plurality of elements are different from said first plurality of elements both as to hardware and operation; and, (c) first controller means coupled to said first and second busses whereby said first plurality of elements communicates with said second plurality of elements.
Claim 2
Dependent Claim
159 words
A data processing system comprising: (a) a first plurality of elements coupled by means of a first common bus to transfer information between said first plurality of elements, said first plurality of elements comprising at least a first, second and third unit wherein said first unit is a first resource shareable by at least the second and third units; (b) a second plurality of elements coupled by means of a second common bus to transfer information between said second plurality of elements, said second plurality of elements comprising at least a fourth, fifth and sixth unit wherein said fourth unit is a second resource shareable by at least the fifth and sixth units, and wherein said second plurality of elements are different from said first plurality of elements both as to hardware and operation; and, (c) first controller means coupled to said first and second busses whereby said first plurality of elements communicates with said second plurality of elements.
Claim 3
Dependent Claim
95 words
The data processing system as recited in Claim 1 including a third common bus coupled to said first controller means, said third common bus having coupled to it a third plurality of elements, said third plurality of elements comprising at least seventh, eight and ninth units, said seventh unit being a third resource sharable by at least the eighth and ninth units, and wherein said third plurality of elements are different from said first and second plurality of elements, and wherein said third plurality of elements communicates with said first and second plurality of elements.
Claim 4
Dependent Claim
97 words
The data processing system as recited in Claim 2 including a fourth common bus coupled to said first controller means, said fourth common bus having coupled to it a fourth plurality of elements, said fourth plurality of elements comprising at least tenth, eleventh and twelfth units, said tenth unit being a fourth resource shareable by at least the eleventh and twelfth units, and wherein said fourth plurality of elements are different from said first, second and third plurality of elements, and wherein said fourth plurality of elements communicates with said first, second and third plurality of elements.
Claim 5
Dependent Claim
51 words
The data processing system as recited in Claim 3 wherein said first, second, third and fourth plurality of elements comprise a first local area network (LAN) and including a second local area network (LAN) coupled to said first controller means, said second LAN comprising said first, second and third common busses.
Claim 6
Dependent Claim
33 words
The data processing system as recited in Claim 4 including a third local area network (LAN) coupled to said first controller means, said third LAN comprising said first, second and third common busses.
Claim 7
Dependent Claim
34 words
The data processing system as recited in Claim 5 including a fourth local area network (LAN) coupled to said first controller means, said fourth LAN comprising said first, second, third and fourth common busses.
Claim 8
Dependent Claim
34 words
The data processing system as recited in Claim 3 including a second local area network (LAN) coupled to a second controller means, said second LAN comprising said first, second, third and fourth common busses.
Claim 9
Dependent Claim
31 words
The data processing system as recited in Claim 7 including a third LAN coupled to said second controller means, said third LAN comprising said first, second, third and fourth common busses.
Claim 10
Dependent Claim
64 words
A local area network controller system comprising: (a) a plurality of local area networks (LANs), each LAN comprising a plurality of shared resource means, each LAN coupled to its shared resource means by a system bus; and, (b) controller means coupled to each system bus of each LAN for communicating with each other, regardless of the type of resource coupled to any given LAN.
Claim 11
Dependent Claim
64 words
A local area network controller system comprising: (a) a plurality of local area networks (LANs), each LAN comprising a plurality of shared resource means, each LAN coupled to its shared resource means by a system bus; and, (b) controller means coupled to each system bus of each LAN for communicating with each other, regardless of the type of resource coupled to any given LAN.
Claim 12
Dependent Claim
119 words
A local area network controller system comprising: (a) a first type of local area network (LAN) comprising a first plurality of shared first type resource means coupled to a first type bus means; (b) a second type of local area network (LAN) comprising a second plurality of shared second type resource means coupled to a second type bus means, and wherein said first plurality of shared first type resource means have different architecture than said second plurality of shared second type resource means; and, (c) controller means coupled to said first type and second type LAN for controlling communications between said first plurality of shared first type resource means and second second plurality of shared second type resource means.
Claim 13
Dependent Claim
119 words
A local area network controller system comprising: (a) a first type of local area network (LAN) comprising a first plurality of shared first type resource means coupled to a first type bus means; (b) a second type of local area network (LAN) comprising a second plurality of shared second type resource means coupled to a second type bus means, and wherein said first plurality of shared first type resource means have different architecture than said second plurality of shared second type resource means; and, (c) controller means coupled to said first type and second type LAN for controlling communications between said first plurality of shared first type resource means and second second plurality of shared second type resource means.
