Abstract
A system is configured to capture a set of interrupts and output the interrupts serially onto an interconnect. The interrupts, which are routed to a destination, may first be packetized such that additional information is associated with the interrupt within the packet.
Claims21
A method, comprising:
- capturing a set of interrupts;
- processing interrupts of said set of interrupts, wherein said processing includes determining at least one Hamming Distance between two interrupts of the set of interrupts;
- outputting serially said processed interrupts of said set of interrupts onto a shared interconnect for routing to at least one destination of a plurality of destinations;
- and
- based on the at least one Hamming Distance, determining if all of said interrupts of said captured set of interrupts which are to be output onto said shared interconnect have been output onto said shared interconnect before processing another set of captured interrupts.

An apparatus, comprising:
- capture circuitry configured to capture a set of interrupts;
- processing circuitry configured to process interrupts of said set of interrupts, wherein said processin includes determining at least one Hamming Distance between two interrupts of the set of interrupts;
- and
- output circuitry configured to output serially said processed interrupts of said set of interrupts onto a shared interconnect for routing to at least one destination of a plurality of destinations,
- wherein based on the at least one Hamming Distance, said processing circuitry is configured to determine if all of said interrupts of said captured set of interrupts which are to be output onto said shared interconnect have been output by said output circuitry before processing interrupts of another set of captured interrupts.
2 more elements
A system having a plurality of physical units, comprising:
- a first physical unit having a destination;
- and
- a second physical unit having:
- capture circuitry configured to capture a set of interrupts;
- processing circuitry configured to process interrupts of said set of interrupts, wherein said processing circuitry is arranged to determine at least one Hamming Distance between two interrupts of the set of interrupts;
- and
- output circuitry configured to output serially said processed interrupts of said set of interrupts onto a shared interconnect for routing to at least one destination of a plurality of destinations, at least one interrupt directed to said destination of the first physical unit,
- wherein based on the at least one Hamming Distance, said processing circuitry is configured to determine if all of said interrupts of said captured set of interrupts which are to be output onto said shared interconnect have been output by said output circuitry before processing interrupts of another set of captured interrupts.
