Description
Technical field
The present invention relates to a kind of usb host controller fast testing system and method thereof, relate in particular to a kind of foundation and related specific USB interface is tested system and method thereof with the quick test of finishing usb host controller by virtual USB equipment and actual USB interface.
Background technology
USB (universal serial bus) (Universal Serial Bus, English abbreviation: USB) be a kind of new interface technology that is applied in personal computer (PC) field.When this type of usb host controller chip of test, adopt basically in conjunction with the USB tool and be used as means of testing at present.Usually, earlier the USB tool is connected into computing machine, load the driver of USB tool then, application program by user model sends instruction at last, indication operating system is tested, and waits for the feedback of operating system then, calculates the usb data transfer rate according to feedback information.Yet in the prior art, there is following shortcoming in the test that utilizes the USB tool to carry out the USB control chip:
1, reduces test speed.Because the USB tool is the single-chip microprocessor system normally, its processing speed generally can't be compared with computer processing speed, therefore, owing to not matching of single-chip microprocessor system and computer processing speed, and reduces whole test speed.
2, waste of manpower resource increases testing cost.Need the tester to carry out associative operation, in test, separately the USB tool is connected into the USB port of computing machine, valuable human resources have been wasted, and owing to need to use the USB tool to test, increased testing cost and, always needed constantly to improve the USB tool along with the continuous change and the raising of test request.
3, increase the probability of makeing mistakes, reduce work efficiency.Because there are quality problems probably in USB tool itself or because some is former thereby cause it to damage, and cause the erroneous judgement of test procedure disconnected.Simultaneously, owing to add manually-operated, increased the probability that test procedure is made mistakes.In addition, when finding USB device operation irregularity, can't determine it is that the port unusually also connects or USB device operation irregularity, therefore can cause the test result mistake, so also need to cause work efficiency to reduce like this by detecting to confirm whether the USB device is working properly.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of usb host controller fast testing system and method thereof, sets up by virtual USB equipment and actual USB interface and related specific USB interface is tested to finish the quick test of usb host controller.
For achieving the above object, a kind of usb host controller fast testing system provided by the present invention comprises: control module, in order to obtain the control of usb host controller; Filtering module is in order to the data packet that receives and the application program of interception user model is sent to usb host controller, to judge whether to exist the test activation of USB device to be measured or the information of end of test (EOT); Virtual USB equipment constitutes test channel in order to make between computing machine and a plurality of actual USB interface; And test module, in order to being connected with a plurality of actual USB interface to be measured respectively, to finish test to the interface of the actual USB device of appointment by virtual USB equipment.
And for achieving the above object, a kind of usb host controller method for rapidly testing provided by the present invention comprises following steps: the control of obtaining usb host controller; Set up virtual USB equipment; Be connected with the interface of a plurality of actual USB device respectively by virtual USB equipment, the test of the interface of the actual USB device of appointment prepared to finish; Activation is to the test procedure of the interface of the actual USB device of appointment; The data packet that the application program of reception and interception user model is sent to usb host controller is to judge whether to exist the test active information of USB device to be measured; If there is not a test active information, then continue to receive and data packet that the application program of interception user model is sent to usb host controller; After receiving the test active information, activation is to the test procedure of the interface of the actual USB device of appointment; Activate the data packet that the back receives and the application program of interception user model is sent to usb host controller in test, to judge whether to exist the end of test information of USB device to be measured; If do not receive end of test information, then continue to receive and data packet that the application program of interception user model is sent to usb host controller; And after receiving end of test information, stop test procedure and return the application program of test result, and end is to the test of the interface of the actual USB device of appointment to user model.
In sum, the invention has the advantages that:
1, gets rid of the influence of USB tool, reduce the cost of research and development and production USB tool.The method that the present invention adopts is directly tested the usb host controller chip, and designs a USB and filter (USB Filter) driver, is responsible for receiving activation/end test instruction, receives after the instruction flow process according to the rules, activation/end test procedure.Return the application program of test result after the end of test (EOT) to user model.Therefore need not to use the USB tool, got rid of the influence of USB tool, reduced the cost of research and development and production USB tool.
2, finish the task of test usb data transmission automatically, fast.The disclosed technical scheme of the present invention need not to use the USB tool, and only utilizes computer terminal just can test.Present computing machine has all surpassed the USB tool from performance and stable aspect, and therefore the precision and the speed of test can be guaranteed.The present invention is when test, use the technology of virtual unit, concrete USB port reflection is become virtual USB equipment, in the actual test, constitute test channel with virtual USB equipment and usb host controller chip, form a data flow path of replying fast in computer-internal, this channel can not delay the transmission of data owing to USB tool or other factors, therefore can finish test assignment fast.And only need flow process according to the rules to activate the dependence test program, just can realize fast automatically testing the USB velocity test, saved the human resources of a large amount of preciousnesses.
