Publication number: 20170024027Abstract: An input device includes an input interface, a near field communication unit and a controlling unit. The near field communication unit receives a device setting information from a portable electronic device. Consequently, the controlling unit reads the device setting information and performs an input setting task corresponding to the device setting information. When the user operates the input interface, a personalized operating signal corresponding to the device setting information is transmitted from the input interface to a computer host that is connected with the input device. Consequently, the computer host performs a corresponding operation. Under this circumstance, it is not necessary to install a corresponding driver in the computer host.Type: ApplicationFiled: October 23, 2015Publication date: January 26, 2017Inventor: CHIH-FENG CHIEN

Patent number: 7738451Abstract: A method and device for flexible, dynamic and optimal buffering in a networking system are provided. Sizes of incoming packets are recognized and the packets are buffered into buffers of appropriate sizes. Usage times of buffers are counted, and during an idle state of the networking system, buffer number and descriptor number are re-calculated based on usage times. Then, buffers and descriptors are re-allocated based on the re-calculated number. By re-allocation, buffer sets with higher usage times are allocated with more buffers, and vice versa, so memory waste is lowered and the overall performance of the networking system is improved.Type: GrantFiled: July 1, 2005Date of Patent: June 15, 2010Assignee: Faraday Technology Corp.Inventors: Chih-Feng Chien, Chun-Chang Huang

Publication number: 20050289254Abstract: A dynamic allocation method for DMA buffers. A DMA controller is directed to move data from an input/output (I/O) device to buffers linked in a buffer ring. Next, free buffers in the buffer ring are detected when the each buffer is full. At least one new buffer is then allocated to the buffer ring when the number of detected free buffers is less than a first threshold value. Further, at least one buffer is released from the buffer ring when the number of detected free buffers exceeds a second threshold value, wherein the second threshold value exceeds the first threshold value, and the free buffers are all buffers in the buffer ring excluding those with data moved thereto by the DMA controller not yet processed by the CPU.Type: ApplicationFiled: June 28, 2004Publication date: December 29, 2005Inventor: Chih-Feng Chien
