Abstract: A method and apparatus for tuning the activity factor of a scan capture phase is described. In one example an activity factor is determined for a die to be tested. The die may be isolated or part of a wafer. A structural scan test is modified to run with an activity factor based on the determined activity factor. The modified structural scan test is run and the die is characterized based on the test.

Abstract: A method and apparatus for providing an efficient, low cost data streaming mechanism from a first bus architecture to a second bus architecture across a bus bridge. Separate read and write data queues are provided in the bus bridge for transfer of data in both directions, and the speed of one of the buses is increased over the speed of the other one of the buses. In one embodiment, the first bus is a PCI bus and the second bus is an internal CPU bus.

Abstract: A transmit circuit operable to synchronize a data transmission is disclosed. The transmit circuit comprises a first circuit configured to transmit a plurality of data segments. The transmit circuit further comprises a second circuit coupled to the first circuit. The second circuit is configured to generate a strobe signal indicating the transmission of a first data segment of the plurality of data segments. The transmit circuit also comprises a third circuit coupled to the second circuit. The third component is configured to receive an acknowledge signal. Based on a logic transition of the acknowledge signal, the third circuit determines the transmission of a second data segment of the plurality of data segments.
