Abstract:
1. A computer system comprising: a plurality of integrated circuits; a routing circuit configured to route a particular data stream with a tag and one or more additional data streams in a non-deterministic aggregate data stream between the plurality of integrated circuits, wherein the routing circuit includes a plurality of ports; a signature analysis register coupled to one of the plurality of ports; wherein the signature analysis register is configured to collect a portion of the aggregate data stream conveyed via said one of the plurality of ports, dependent upon whether the signature analysis register receives a tag with said portion identifying said portion as the particular data stream; and one or more signature analysis control registers; wherein each signature analysis control register is coupled to one or more signature analysis registers, wherein each signature analysis control register is configured to provide a control tag to each signature analysis register, and wherein each signature analysis register is configured to only collect data whose tag matches the control tag.
