Abstract:
A method for injecting scanned data into a plurality of rings, each such ring being located in a different system device, each ring having one or more registers, each register corresponding to one or more database fields and wherein a plurality of said devices comprise a scan path, and wherein each ring is selected from a plurality of possible rings, the method comprising:configuring a utility buffer for a specified scan path by combining one or more fields from a database having the one or more fields; locking one specified ring on each of a plurality of devices specified on said specified scan path; allowing a desired value to be written concurrently into the one or more fields that correspond to the each of the plurality of devices; and allowing the utility buffer to be written back to by the one or more interposed status registers of the one specified ring in each of the plurality of devices to cause the data in the status registers to be scanned out for reading into the fields of the utility buffer.
