Abstract:
PROBLEM TO BE SOLVED: To solve the problem of there being the possibility that a serial queue, such as a PCI bus interface, is turned to be a bottleneck resulting in the latently annihilating benefits on performance for use of a high-speed network switching interface. SOLUTION: This system having an inter-remote bus high-speed switching interface is provided with a switching mechanism, to which a plurality of bus interfaces are connected. A programmable flow queue, having a plurality of parallel logical flow queues, is used for scheduling a packet in accordance with the protocol request of a remote bus interface.
Abstract:
A method and circuit for using signature analysis testing techniques without deriving star/stop and clock signals from the device under test. In this invention, a start signal is derived from the output data stream by configuring that data stream to indicate when the test stream begins. The stop signal is derived by counting the predetermined number of data bit cells to be measured and issuing the stop signal when the count is reached. Data clock pulses are derived as a fraction of test system clock pulses at a frequency approximately equal to the bit cell frequency. The data clock pulse is located at the midpoint of the bit cell time so that the data stream is clocked into the signature analysis tester at a stable point.
