20100070658 | METHOD OF COMMUNICATION BETWEEN A PROTOCOL-PROCESSING UNIT AND AN INPUT/OUTPUT (I/O) DEVICE THROUGH A DEVICE INTERFACE CONTROLLER - A method of communication between a protocol-processing unit and an input/output (I/O) device through a device interface controller includes configuring the protocol-processing unit to write command/message data in a predefined write file, and configuring the device interface controller to translate the command/message data written in the predefined write file into a corresponding command/message and to transmit the corresponding command/message thus translated to the I/O device. A system that includes the protocol-processing unit and the device interface controller is also disclosed. | 03-18-2010 |
20090300223 | METHOD FOR COMMUNICATION BETWEEN AN ELECTRONIC DEVICE AND A TARGET INPUT/OUTPUT DEVICE IN A SECURE DIGITAL INPUT/OUTPUT CARD THROUGH A SECURE DIGITAL INTERFACE, AND SYSTEM FOR IMPLEMENTING THE SAME - A method for communication between an electronic device and a target input/output (I/O) device in a secure digital input/output (SDIO) card through a secure digital (SD) interface is provided. The SDIO card includes a SDIO controller. The method includes the steps of: configuring the electronic device to write an I/O command packet at a designated address accessible to both the electronic device and the SDIO controller, the I/O command packet including a command for controlling the operation of the target I/O device; and configuring the SDIO controller to control the operation of the target I/O device according to the I/O command packet written at the designated address. | 12-03-2009 |
