Claim Text:
1. An out-of-order message filter comprising: a content-addressable memory (CAM) configured to search a memory of the CAM for a source identifier of a first received message that matches a source identifier of a second received message and output a CAM address of the source identifier of the first received message; a random-access memory (RAM) configured to use the CAM address to read from a memory of the RAM a sequence identifier of the first received message; and a comparator, implemented at least in part in hardware, configured to perform a comparison between the sequence identifier of the first received message read from the RAM to a sequence identifier of the second received message, wherein the comparison determines whether the first received message was transmitted before or after the second received message, wherein the CAM is configured to auto-invalidate the source identifier of the first received message stored in the memory of the CAM after the source identifier of the first received message is matched to the source identifier of the second received message.
