Patent number: 7779083Abstract: A message transmitting queue delivers messages between a source controller and a destination controller. According to the message transmitting request of the source controller, sequentially distribute the free message row of the message transmitting queue, and set the message row to the distributed state. After the source controller writes the message of the message row, set the message row to the written state. At this moment, when the message row is in the position that is read sequentially by the destination controller, a read request is issued, so that the destination controller reads the message according to the read request when the reading completes, clears the distributed signal and the written signal, so that the message row goes back to the free state. When the message transmitting queue has no free message row, a no free message row signal to inform the source controller is issued.Type: GrantFiled: November 15, 2002Date of Patent: August 17, 2010Assignee: Via Technologies, Inc.Inventors: Wei-Pin Chen, Chun-Hua Tseng

Patent number: 7526594Abstract: A method of Universal Serial Bus (USB) data transfer is provided. In one embodiment, a USB device supports a bulk-only transmission mode to transfer data with a USB host, and the USB device comprises a bulk endpoint buffer storing data transferred between the USB device and the USB host through a bulk endpoint of the USB device and an interrupt endpoint buffer storing data transferred between the USB device and the USB host through an interrupt endpoint of the USB device. A first portion of data stipulated to be transferred through the bulk endpoint is stored with the interrupt endpoint buffer. A data path through which data is transferred between the USB host and the USB device is switched to lead to either the bulk endpoint buffer or the interrupt endpoint buffer with a multiplexer.Type: GrantFiled: December 11, 2006Date of Patent: April 28, 2009Assignee: Via Technologies, Inc.Inventors: Chun-Hua Tseng, Yu-Tin Hsu

Patent number: 7215578Abstract: A method for driving a flash memory and flash memory apparatus thereof are provided. The flash memory apparatus comprises a flash memory controller and a flash memory. At first, a voltage level of the parameter definition pin is detected by the flash memory controller to obtain the basic configuration of the flash memory when the flash memory controller is in a reset mode. Next, a fundamental access operation is performed on the flash memory by the flash memory controller according to the basic configuration. Then, a detail configuration is read from a specific data block of the flash memory. At last, the flash memory is driven according to the basic configuration and the detail configuration of the flash memory.Type: GrantFiled: January 19, 2006Date of Patent: May 8, 2007Assignee: Via Technology, Inc.Inventors: Chin-Yi Chiang, Chun-Hua Tseng
