Abstract
The utility model provides a universal serial bus (USB) slave device simulating device which mainly comprises a personal computer interface (PCI) circuit, a protocol processing circuit, and a universal serial bus (USB) connecting device. Users can install the simulating device in a computer with a PCI slot and connect the simulating device with a USB main device through the USB connecting device. The protocol processing circuit of the simulating device can convert a communication protocol sent by the USB main equipment into a PCI data package and send the PCI data package to the PCI circuit, and a response data package is sent back to a USB main port device. Therefore, a USB slave device can be simulated, such as a USB keyboard, a USB mouse and a USB mobile memorizer.
Description
(1) technical field:
The present invention relates to the communications field, specifically a kind of general-purpose serial bus USB (Universal Serial BUS) slave unit analogue means.
(2) background technology:
USB (Universal Serial BUS) is an external bus standard, in issue in 1996, is used for being connected and communication of standard computer and external unit, has upgraded to the USB2.0 version at present, in consumer electronics product, obtains using very widely.Various portable electric appts are like digital camera, portable hard drive, mouse, keyboard etc., all with the data transmission interface of USB interface as standard.
USB device can be divided into main equipment (HOST) and slave unit (SLAVE), and all data stream all occur between main equipment and the slave unit alternately.Main equipment is responsible for initiatively initiating operation, and slave unit receives the operational order of main equipment and makes accordingly and replying.The USB host device interface is installed on the main frame usually, and slave unit is generally portable electric appts such as USB flash disk, mouse, keyboard.
Peripheral interconnection PCI (Peripheral Component Interconnect) technology is a kind of local parallel bussing technique that is widely used on the computing machine, and it does not depend on specific processor, between CPU and system bus, realizes the coordination and the transmission of data.Pci bus is supported 32 and 64 two kinds of bit wides, and clock frequency is 33MHz, and its transfer rate can reach 133MB/s (32 bit width) or 266MB/s (64 bit width).Through pci bus, can realize the high-speed data exchange of peripheral hardware and computing machine.
(3) summary of the invention:
When test USB host device interface, need to insert dissimilar slave units usually and carry out with it alternately, thereby increased testing cost, and the pumping signal of also input error easily is to detect the fault-tolerant ability of host device interface.Therefore, we have proposed a kind of analogue means that can simulate any USB slave unit interface.This USB slave unit analogue means; Possess a USB slave unit interface, a protocol treatment circuit and a pci interface; Its USB slave unit interface links to each other with the USB host device interface, and the other end links to each other with computing machine through pci interface, realizes the purpose of a USB slave unit of simulation.
Through this analogue means, can simulate various USB slave units easily, especially significantly reduced the input of procuring equipment at predevelopment phase, can be widely used in the research and development and test of each item USB host device interface.

(5) embodiment
The invention discloses a kind of USB slave unit analogue means.
Fig. 1 has provided the disclosed USB slave unit of the present invention analogue means and has realized block diagram 100.The user connects the usb 1 02 of USB main equipment and this device with the direct-connected line of USB; The order of USB master transmissions and packet are sent into protocol treatment circuit 104 through USB interface, and 104 pairs of USB orders of protocol treatment circuit and packet are handled, and send to pci interface circuit 106 according to PCI protocol requirement form; Communicate with computing machine via this pci interface circuit 106; Accomplish the enumeration process of USB slave unit, after accomplishing the enumerating of USB slave unit, computing machine can pass through the pci interface circuit; 106 to protocol treatment circuit 104 transmission data; And by being transmitted to usb circuit 102 after protocol treatment circuit 104 processing, to realize the needed slave unit function of user, like the click action of simulation USB left mouse button or the actuation of keys of USB keyboard.
Claims (1)
1. USB slave unit analogue means; It possesses a USB slave unit interface, a protocol treatment circuit and a pci interface; Its USB slave unit interface links to each other with the USB host device interface, and the other end links to each other with computing machine through pci interface, realizes the purpose of a USB slave unit of simulation.
