A 9B/10B encoding method is used for encoding a 9-bit source sequence set, including first type, second type and third type of 9-bit source sequence sets, into a 10-bit target sequence set. The first type of 9-bit source sequence set only includes 9-bit source sequences with difference values of 1 and −1. After inserting 1-bit data '0' or “1” in each sequence, each sequence is encoded as a 10-bit target balanced sequence; the second type of 9-bit source sequence set alternatively includes only 9-bit source sequences with difference values of 3 or −3. After inserting 1-bit data “0” or “1” into each sequence, each sequence is encoded into a pair of 10-bit target unbalanced sequences with a difference value of ±2; each sequence in the third type of 9-bit source sequence set is encoded as a pair of 10-bit target unbalanced sequences that are opposite numbers for each other.

9B/10B encoding and decoding method

The present invention provides a multi-rate bidirectional transmission system. A sending device and a receiving device transmit data in a bidirectional way through a cable. The multi-rate bidirectional transmission system communicates with a reverse configuration packet by sending a forward configuration packet at a preset rate in a time-division manner, selects a serial rate jointly supported by the sending device and the receiving device, and selects a training sequence length. Then, the sending device and the receiving device perform equalization training at the selected serial rate with the selected training sequence length, thus avoiding searching the serial rate and presetting the training sequence length in the worst case, thus simplifying the design and improving the link training speed.

The present invention discloses a dual-mode USB device, which includes a USB2.0 controller, a dual-mode USB2.0 interface module and a USB interface. The dual-mode USB device alternatively works in a USB2.0 standard mode or a USB2.0 extended mode. In the USB2.0 standard mode, DP and DM signals of the USB2.0 interface are connected to a remote USB interface by DC coupling, and is compatible with remote devices using USB2.0 standard signals and protocols; in the USB2.0 extended mode, DP and DM signals of the USB2.0 interface are connected to the remote USB interface by AC coupling, which is compatible with remote devices supporting the USB2.0 extended mode.

An intelligent mobile power supply and a method for USB data communication therewith. The intelligent mobile power supply includes a battery, a charging control module, a discharging control module, a first USB interface and a second USB interface. In the single charging mode, a charged device receives a discharge of the intelligent mobile power supply through the discharging control module, but the intelligent mobile power supply does not perform USB data communication with the charged device. While in the charging and communication mode, the charged device receives the discharge of the intelligent mobile power supply through the discharging control module and can perform USB data communication with the intelligent mobile power supply through the first USB interface simultaneously. The second USB interface is connected with the charging control module, and the second USB interface can be connected with a power adapter or a PC host to charge the battery.

Charging detection and control apparatus

A control apparatus with multiple flash memory card channels includes a host side port unit, an instruction data processing unit, and flash memory card port units. The host side port unit exchanges a host side instruction and host side read/write data with a high-speed serial communication protocol host side. The flash memory card port units respectively exchange flash memory card instructions and flash memory card read/write data with a plurality of flash memory cards. An instruction from the high-speed serial communication protocol host side is divided into multiple sub-instructions to be respectively transmitted to the flash memory card port units and exchange of instruction and data with a plurality of flash memory cards is carried out in a coincident period of time so as to achieve the purposes of expanding access capacity and increasing access speed, reducing the operation cost of products, and enhancing flexibility of use of flash memory cards.
