When described external USB equipment is from equipment, described CPU is additionally operable to determine what described external USB equipment was supported
Velocity mode；CPU determines the velocity mode that external USB equipment is supported, i.e. detection determine external USB equipment be full-speed device,
Low-speed device or high-speed equipment, this detection determines that mechanism is similar with detection device rate during USB enumeration, the most superfluous
State.
If described external USB equipment supports fast mode, the most described CPU is additionally operable to the read-write of described external USB equipment
Data are routed to described EHCI controller；Described USB primary module is for sending equipment disconnecting message to described CPU；Described
CPU is additionally operable to build corresponding descriptor at the outside Double Data Rate synchronous DRAM DDR coupled, and retouches described
The address information stating symbol corresponding is written in described second depositor；
If described external USB equipment supports Full-Speed mode or low-speed mode, the most described CPU is additionally operable to described external USB
The read-write data of equipment are routed to described OHCI controller；Described USB primary module is for sending equipment disconnecting to described CPU
Message；Described CPU is additionally operable to build corresponding descriptor at the outside DDR coupled, and by address letter corresponding for described descriptor
Breath is written in described first depositor.
Optionally, as shown in Figure 4, described USB primary module also includes buffer area；
Described USB primary module is additionally operable in the descriptor acquiring in described DDR to described buffer area, and to described description
Symbol resolves；
If descriptor represents that needs are additionally operable to from described to described external USB equipment sending data, the most described USB primary module
DDR obtains the data needing to send, and sends to described external USB equipment；
If descriptor represents that needs obtain data from described external USB equipment, the most described USB primary module is additionally operable to receive
The data that described external USB equipment sends, are stored in described relief area, and write in the DDR space that pointer in descriptor points to.
Optionally, as shown in Figure 4, described USB includes the 3rd depositor and direct memory access (Direct from module
Memory Access, DMA)；
When described external USB equipment is main equipment, described USB disappears for initiating disconnecting to described CPU from module
Breath, described CPU builds corresponding descriptor in outside DDR, and the entry address of descriptor is written to the described 3rd deposits
In device, described DMA is for obtaining described descriptor according to described entry address in described DDR；
Described DMA is additionally operable in described DDR obtain corresponding data and be transferred to described external USB equipment, transmits data
After update the descriptor state in described DDR,
Or,
Described DMA is additionally operable to receive the data of described external USB equipment transmission and be written back in described DDR, receives number
The descriptor state in described DDR is updated after according to.
In the embodiment of the present application, when being not inserted into external USB equipment on SoC, it is polled detection according to predetermined period,
After outside USB device identification success, no longer detecting, external USB equipment is extracted and is restarted automatic regular polling detection afterwards.
It should be noted that the USB correlation module of the USB module related in the embodiment of the present application and other correspondences and setting
Standby, such as USB interface, external USB equipment etc., both can support USB1.0, USB2.0, USB3.0, it is also possible to supports USB3.1,
It is not construed as limiting herein.
Below in conjunction with concrete scene, the embodiment of the present invention is introduced.
1) assuming that local terminal (base station side) is main equipment, opposite end (external USB equipment) is from equipment, it is assumed that external USB equipment
For USB flash disk, the selector within SOC is gated USB primary module, identify enumerating from equipment according to main equipment pattern (holotype)
Journey completes the identification of insertion equipment:
After being inserted into USB port from equipment USB flash disk, USB primary module first carries out speed negotiation with USB flash disk and shakes hands, after shaking hands successfully
As long as USB flash disk is in place, no longer poll identification.
If USB flash disk supports High-speed (fast mode), then it is routed to enhancement mode host controller interface (English complete
Claim: Enhanced Host Controller Interface, English abbreviation: EHCI) controller；
If USB flash disk supports Full-speed (Full-Speed mode) or Low-speed (low-speed mode), then it is routed to open
HCI (English full name: Open Host Controller Interface, English abbreviation: OHCI) controller.So
Rear USB primary module sends equipment to CPU and connects (Connect) interruption, and CPU builds corresponding descriptor at outside DDR subsequently, and
It is written to information such as base address in the first depositor of USB primary module or the second depositor (see and be routed to EHCI controller also
Being OHCI controller, if being routed to OHCI controller, being the most then the first depositor, if being routed to EHCI controller, the most then
It is the second depositor).
Descriptor in DDR is got in internal Buffer (relief area) by USB primary module, then resolves it, as
Really descriptor is shown to be needs and sends out data to USB flash disk, then need first to take the data needing to send from DDR, then USB flash disk is initiated OUT
Transmission (i.e. transmits data to USB flash disk)；If descriptor is shown to be needs and obtains data from USB flash disk, then USB primary module is first to USB flash disk
Initiate IN operation (i.e. receiving the data of USB flash disk transmission), then retaking of a year or grade to data is stored in Buffer, then writes pointer in descriptor
In the DDR space pointed to.
When the main equipment of PC etc inserts, then cannot shake hands successfully, be strobed into USB by selector and switch to from module
From pattern, according to step 2) being identified of describing.
2) assume that local terminal (base station side) is that opposite end (external USB equipment) is main equipment from equipment, with outside USB device be
Illustrate as a example by PC (Personal Computer)；
Selector MUX within SOC gates USB complete from setting from module, the enumeration process of cooperation opposite end main process equipment
Standby identification；
When the main equipment of PC etc inserts, and now USB initiates disconnecting from module to CPU, and CPU builds in DDR
Corresponding descriptor, and the entry address of descriptor is written to USB from the 3rd depositor of module, then DMA according to
This entry address takes descriptor in removing DDR, USB2.0Device resolves descriptor, if PC USB to be taken is from the number of module
According to, then fetch data during DMA needs DDR and be then transmitted, after end of transmission, update the descriptor state in DDR；If
PC sends data to USB from module, then DMA needs in the write back data that receives to DDR, and updates the description in DDR
Symbol state.
When USB flash disk etc after equipment is inserted into USB port, then cannot shake hands successfully.
3) automatic regular polling detection during inserting without equipment, repeats step 1 and 2, after equipment insertion identification principal and subordinate's success not
Detecting, equipment is extracted and is restarted automatic regular polling detection afterwards again.
