    摘要: A bulk transfer control method of a universal serial bus (USB) device includes a timer for counting transmission time of a buck transfer. When the transmission time counted reaches a transmission time setting value, a trigger signal is issued to a transfer end event generator. Then, the transfer end event generator issues a transfer end event signal to a data processing unit so as to end the bulk transfer. Moreover, a USB device and its bulk transfer control circuit are also provided.

    摘要: An Ethernet physical layer test system and method, wherein a signal pattern generator is utilized to generate repeatedly a signal pattern frame required by the test items of the Ethernet physical layer according to a transmission procedure of a medium access controller; meanwhile, the signal pattern generator generates a control signal for switching a multiplexer, so as to control the transmission of a signal pattern frame. The Ethernet physical layer receives the signal pattern frame and outputs a test packet to a measurement instrument via a twisted-pair, for testing and analyzing quality of signals output by the Ethernet physical layer. Through the application of this Ethernet physical layer test system and method, the time required for testing the Ethernet physical layer can be effectively reduced, thus simplifying the complexity of an algorithm in testing the Ethernet physical layer.
