摘要： A data receiver circuit in a receiving chip provides the capability to characterize an interface, which includes one or more inter-chip communication lines, between a transmitting chip and the receiving chip by transmitting the data across a primary data path and a secondary data path, latching the data in the secondary data path using a clock signal that is skewed relative to a clock signal used to latch the primary data path, comparing the data latched from the primary and secondary data paths, and recording errors. Because the primary data path is not impacted by the test cycle, the test cycle may be run while data associated with applications running on the system are transmitted across the inter-chip communication lines.

摘要： A redundant communication system for providing data communication between a first computing node and a second computing node. A transmitter is provided as part of the first computing node. A receiver is provided as part of the second computing node. A first signal line carries a first data signal. The first signal line electrically couples the transmitter with the receiver. A second signal line carries a second data signal redundant to the first signal. The second signal line electrically couples the transmitter with the receiver. The receiver evaluates the first data signal to determine the presence of an error and the second node uses the second data signal if an error is detected in the first data signal.

摘要： An apparatus, system, and method are disclosed for assessing error over a communication link. The apparatus for assessing error is provided with a logic unit containing a plurality of modules configured to execute the necessary steps of creating one or more test packets, determining an amount of test packets to send over a communication link to a receiving node, sending a plurality of test packets over the communication link to a receiving node, interspersing test packets throughout a plurality of data packets such that the receiving node is able to continually process the data packets, and checking test packets received by the receiving node for errors.
