Technical field
The present invention relates to multiplexed port systems, more particularly to one kind to be based on USB3.0 multiplexed port system.
Background technique
In general mobile device, such as mobile phone, tablet computer, only one equal USB port can be used, this is to part For SOC comprising multiple independent particle systems, need to might have inconvenient feelings with host equipments such as PCs when interacting Condition.
For example, in SOC (System on a Chip, System on Chip/SoC or on piece comprising Modem function and application processor System) in, Modem is usually an independent subsystem, and other than carrying out data interaction with master operating system, itself is also required to Carry out firmware upgrade and debugging etc. operation, generally exploitation the independent development interface of early application (such as UART interface) complete (see Fig. 1).To later period SOC product, there is usually one the USB ports that user can contact, this USB port is usually by host CPU and main operation Although the transmission of the agreement in USB3.0 or USB2.0 may be implemented in system control, in the prior art, USB3.0 interface, but in reality Use process can only realize that one of USB3.0 or USB2.0 agreement carry out data transmission, and only support a USB device job. For the hardware without independent debugging interface, needing to carry out the upgrading of Modem subsystem firmware, system debug, AT order test It when Deng requesting, is required to carry out transfer by master operating system, but thus occur the problem that on the one hand influence main operation System operates normally, and occupies master operating system resource;On the other hand, it when master operating system itself is unstable, will have a direct impact on The operations of Modem increase the maintenance cost of complexity and software, inconvenient for use.
Summary of the invention
The technical problem to be solved in the present invention is to provide one kind based on USB3.0 multiplexed port system, realizes same Two USB devices that can be worked independently simultaneously are supported on USB3.0 device port, are assisted respectively by USB2.0 agreement and USB3.0 It discusses while carrying out data transmission, improve equipment operating efficiency, improve system stability.
The present invention is implemented as follows: a kind of be based on USB3.0 multiplexed port system, the port USB3.0 is had including one Equipment end SOC, the port USB3.0 of the equipment end are connect with a host side with the port USB3.0 by USB3.0 cable And carry out data transmission, the equipment end includes application processor, subsystem processor and USB module, the application processor The port USB3.0 for passing through USB module and equipment end respectively with subsystem processor connects and carries out signal transmission, the application Processor connect and carries out data transmission with subsystem processor;
The USB module includes that independently operated USB2.0 controller and USB3.0 controller, the USB2.0 are controlled simultaneously Device processed and USB3.0 controller pass through the port USB3.0 that USB2.0PHY module connects equipment end with USB3.0PHY module respectively, The data transmission of USB2.0 agreement and USB3.0 agreement is carried out respectively.
Further, the USB2.0 controller include internal buffer management module, USB2.0 consultative management module and Data transmit-receive management module.
Further, the USB3.0 controller includes internal buffer management module, USB3.0 consultative management module, number According to transmitting-receiving management module and USB3.0 link management module.
Further, the USB2.0PHY module and USB3.0PHY module include serial/parallel conversion module, signal generation Sending module and signal receive parsing module, carry out the conversion between digital signal and analog signal.
Further, the application processor is connect with USB3.0 controller, and the subsystem processor and USB2.0 Controller connection.
Further, the subsystem processor is Modem processor.
The present invention has the advantage that being realized by two independently operated USB controllers of setting non-interfering The data of USB2.0 agreement and USB3.0 agreement transmission, so that subsystem processor can be direct in the equipment with subsystem It is transmitted by USB interface, does not need to carry out transfer by application processor, substantially increase the stability and operation effect of equipment Rate.
