Abstract
A method of directly transferring data across a CompactPCI™ backplane (170) via a fully meshed orthogonal network (370). The CompactPCI backplane (170) incorporates a different type connector at its P4 location, in conjunction with a standard family of IEC 61074 connectors at its P1, P2, P3, and P5 locations, to provide high speed data transfer with additional shielding and noise control.
Claims25
A Compact peripheral component interconnect (CompactPCI) backplane comprising:
- a plurality of CompactPCI connectors;
- and
- a plurality of channels in each CompactPCI connector of a portion of said plurality of CompactPCI connectors;
- wherein:
- said pluralities of channels are interconnected to form an orthogonal network.
A Compact peripheral component interconnect (CompactPCI) backplane comprising:
- N P1 connectors parallel to each other;
- N P2 connectors parallel to each other and adjacent to said N P1 connectors;
- N P3 connectors parallel to each other and adjacent to said N P2 connectors;
- N P4 connectors parallel to each other and adjacent to said N P3 connectors;
- N P5 connectors parallel to each other and adjacent to said N P4 connectors;
- N channels in each of said N P4 connectors;
- and
- N board receivers;
- wherein:
- N is an integer greater than two;
- said pluralities of P1, P2, P3, and P5 connectors are connectors in a first family;
- said plurality of P4 connectors are connectors in a second family different from said first family;
- a first one of said N P1 connectors, a first one of said N P2 connectors, a first one of said N P3 connectors, a first one of said N P4 connectors, and a first one of said N P5 connectors form a first one of said N board receivers;
- a second one of said N P1 connectors, a second one of said N P2 connectors, a second one of said N P3 connectors, a second one of said N P4 connectors, and a second one of said N P5 connectors form a second one of said N board receivers adjacent to said first one of said N board receivers;
- a third one of said N P1 connectors, a third one of said N P2 connectors, a third one of said N P3 connectors, a third one of said N P4 connectors, and a third one of said N P5 connectors form a third one of said N board receivers adjacent to said second of said N board receivers;
- and
- said N channels are interconnected to form an orthogonal network comprising:
- a first one of said N channels in said first one of said N board receivers coupled to itself;
- a first one of said N channels in said second one of said N board receivers coupled to a second one of said N channels in said first one of said N board receivers;
- a first one of said N channels in a third one of said N board receivers coupled to a third one of said N channels in said first one of said N board receivers;
- a second one of said N channels in said second one of said N board receivers coupled to itself;
- a second one of said N channels in said third one of said N board receivers coupled to a third one of said N channels in said second one of said N board receivers;
- and
- a third one of said N channels in said third one of said N board receivers coupled to itself.
A method of data transfer across a Compact peripheral component interface (CompactPCI) backplane comprising:
- directly transferring a first set of data from a first board receiver in said CompactPCI backplane to a second board receiver in said CompactPCI backplane;
- and
- directly transferring a second set of data from said first board receiver to itself.
