| 20110103224 | DATA COMMUNICATION SYSTEM, COMMUNICATION DEVICE, AND COMMUNICATION METHOD - A data communication system for starting transmission and reception of target data for processing upon recognition that switching between communication modes is completed. The data communication system includes a master communication device and a slave communication device that continuously perform, at a time of switching from half-duplex communication to full-duplex communication, (i) a handshake using a directional control code indicating the switching and a preamble code indicating completion of the switching and (ii) a handshake using the preamble code and an acknowledge code indicating receipt of the preamble code, whereby each of the devices recognizes that the switching between communication modes by the opposite device is completed and starts transmission and reception of the target data. | 05-05-2011 |
| 20110141898 | COMMUNICATION SYSTEM, COMMUNICATION DEVICE, INTEGRATED CIRCUIT, AND COMMUNICATION METHOD - A communication system includes communication devices that are connected with one another in a ring via a serial link. In the communication system, one communication device issues a standby packet for causing each communication device connected to a part of the link that is not involved with data transfer to switch to standby mode. Each communication device connected to this part of the link relays the standby packet from an immediately preceding communication device in the link to an immediately succeeding communication device in the link, and after relaying the standby packet, causes the own device to switch to standby mode. Further, a communication device that performs communication with said one communication device issues a loopback packet for causing each communication device connected to a part of the link that is involved with data transfer to switch to loopback mode. Each communication device connected to this part of the link relays the loopback packet from an immediately preceding communication device in the link to an immediately succeeding communication device in the link, and after relaying the loopback packet, causes the own device to switch to loopback mode. | 06-16-2011 |
| 20110182216 | INTERFACE DEVICE, COMMUNICATIONS SYSTEM, NON-VOLATILE STORAGE DEVICE, COMMUNICATION MODE SWITCHING METHOD AND INTEGRATED CIRCUIT - An interrupt request cannot be transmitted while a data read command or a data write command transmitted from a host device to a slave device is being processed in a half-duplex mode. Disclosed are a host device and a slave device that are set to a full-duplex mode by temporarily switching the communication direction of a first transmission channel or a second transmission channel after completing transmission and reception of a predetermined number of data packets in the half-duplex mode. The host device or the slave device can thus transmit an interrupt request, such as a request associated with a wait status or a busy status, to its communication target using the temporary full-duplex mode. This enables the host device or the slave device to process such an interrupt request during high-speed data transfer performed in the half-duplex mode. | 07-28-2011 |
