[0051] The multiple clients 101 correspond to the multiple processing devices 103 one by one, that is, each processing device 103 corresponds to a unique client 101 .

[0052] Figure 2 Schematic diagram of another system architecture provided by the embodiment of the present application. Figure 2 As shown, the system architecture may include multiple clients 201 , a server 202 , multiple USB conversion devices 203 , and multiple processing devices 204 .

[0053] The client 201 and the server 202 are connected via a network. The network may be a local area network or a wide area network.

[0054] The server 202 and the USB conversion device 203 are connected via a network, which may be a local area network or a wide area network.

[0055] The USB conversion device 203 and the processor 204 are connected via a USB data line.

[0056] The multiple clients 201 correspond to the multiple processing devices 204 one by one.

[0057] There may be a one-to-one correspondence between the multiple USB conversion devices 203 and the multiple processing devices 204, that is, each processing device 204 corresponds to a unique USB conversion device 203. Each USB conversion device 203 in the multiple USB conversion devices 203 may correspond to two or more processing devices 204 in the multiple processing devices 204.

[0058] The client is the client of the processing device, which may include a USB device and a client component. The server is an independent physical server. The USB conversion device is a device that can convert a signal into a USB signal. The processing device is a device that can perform data processing.

[0059] It should be understood that Figure 1 and Figure 2 This is an exemplary description of the system architecture of the present application and does not limit the system architecture of the present application.

[0060] Based on the above system architecture, Figure 3 1 is a flowchart of a method for processing instructions provided in an embodiment of the present application. The method for processing instructions is described from the perspective of a cloud desktop system. The cloud desktop system may include multiple clients, servers, and multiple processing devices, and the multiple clients correspond to the multiple servers one by one. Figure 3 As shown, the instruction processing method may include the following steps.

[0061] 301. The first client sends an operation instruction to a server in response to an operation of a user through a USB device.

[0062] Correspondingly, the server receives the operation instruction from the first client.

[0063] The first client is any client among the multiple clients.

[0064] When users need to perform operations in the process of using the cloud desktop system, they can use USB devices to perform operations. USB devices can include USB keyboards, USB mice, USB microphones and other input devices connected via USB.

[0065] The first client can detect the operation performed by the user through the USB device, and then generate an operation instruction corresponding to the operation in response to the operation of the user through the USB device, and then send the operation instruction to the server. The first client can send the operation instruction to the server through the network. The operation instruction is an instruction related to the user operation. The operation instruction may include the identification of the first client.

[0066] 302. The server converts the operation instruction into a USB signal.

[0067] After receiving the operation instruction, the server can convert the operation instruction into a USB signal. The server can convert the operation instruction into a USB signal according to the USB protocol.

[0068] The server may first parse the operation instruction to obtain the identifier of the first client and the operation data, and then convert the operation data into a USB signal according to the USB protocol.

[0069] 303. The server sends a USB signal to the first processing device.

[0070] Accordingly, the first processing device receives the USB signal from the server.

[0071] The first processing device is a processing device corresponding to the first client among the multiple processing devices.

[0072] The server stores a first correspondence between a plurality of clients and a plurality of processing devices. Exemplarily, the first correspondence may be as shown in Table 1:

[0073]

[0074] Table 1 The first correspondence

[0075] Here, m is an integer greater than 1.

[0076] Therefore, the server may determine the identifier of the first processing device corresponding to the identifier of the first client among the multiple processing devices according to the first corresponding relationship, and then may send a USB signal to the first processing device according to the identifier of the first processing device.

[0077] After receiving the USB signal, the first processing device can process the USB signal. The first processing device can trigger a central processing unit (CPU) interrupt according to the USB signal, and then respond to the CPU interrupt and transmit the USB signal to the operating system according to the USB protocol, and the operating system processes the USB signal.

[0078] exist Figure 3 In the instruction processing method shown, the client does not send the operation instruction directly to the corresponding processing device, but first sends it to the server, which converts the operation instruction into a USB signal and then sends it to the processing device. Since the USB signal is a hardware signal, the operating system will not affect the processing of the USB signal by the processing device, so the compatibility of the system can be improved. In addition, since the cloud desktop system uses a bare metal solution, the stability and performance of the system can be improved.

[0079] Based on the above system architecture, Figure 4 1 is a flowchart of another instruction processing method provided by an embodiment of the present application. The instruction processing method is described from the perspective of a cloud desktop system.

The server uses multiple USB interfaces to connect multiple processing devices through USB data cables. It can be seen that the server extends a USB interface for each of the multiple processing devices, and the server uses the USB interface extended for each processing device to connect to the corresponding processing device through a USB data cable.

[0082] It should be understood that the number of USB interfaces expanded by the server may also be greater than the number of processing devices.

[0083] After the server is connected to multiple processing devices via USB data cables, multiple virtual USB devices can be generated, and the multiple virtual USB devices correspond to the multiple processing devices one by one, that is, a corresponding virtual USB device can be generated for each of the multiple processing devices. The virtual USB device corresponding to each processing device may include a virtual USB keyboard, a virtual USB mouse, a virtual USB microphone, etc.

[0084] 402. The first client sends an operation instruction to the server in response to the user's operation through the USB device.

[0085] Correspondingly, the server receives the operation instruction from the first client.

[0086] The detailed description of step 402 may refer to the description of step 301 .

[0087] 403. The server converts the operation instruction into a USB signal of the first virtual USB device.

[0088] After receiving the operation instruction, the server may convert the operation instruction into a USB signal of the first virtual USB device. The first virtual USB device is a virtual USB device corresponding to the first client among the multiple virtual USB devices.

[0089] The server can first parse the operation instruction to obtain the identification and operation data of the first client, and then determine the first virtual USB device corresponding to the identification of the first client based on a first correspondence between multiple clients and multiple processing devices, and a second correspondence between multiple virtual USB devices and multiple processing devices, and then convert the operation data into a USB signal of the first virtual USB device according to the USB protocol.

[0090] 404. The server sends a USB signal to the first processing device.

[0091] Accordingly, the first processing device receives the first processing device from the server.

[0092] The detailed description of step 404 may refer to the description of step 303 .

[0093] exist Figure 4 In the instruction processing method shown, the client does not send the operation instruction directly to the corresponding processing device, but first sends it to the server, which uses the Keyboard Video Mouse (KVM) technology to convert the operation instruction into the USB signal of the corresponding virtual USB device and then sends it to the processing device. Since the USB signal is a hardware signal, the operating system will not affect the processing of the USB signal by the processing device, so the compatibility of the system can be improved. In addition, since the cloud desktop system uses a bare metal solution, the stability and performance of the system can be improved.

[0094] Based on the above system architecture, Figure 5 1 is a flowchart of another instruction processing method provided by an embodiment of the present application. The instruction processing method is described from the perspective of a cloud desktop system. The cloud desktop system may include multiple clients, servers, multiple USB conversion devices, and multiple processing devices, and the multiple clients correspond to the multiple servers one by one. Figure 5 As shown, the instruction processing method may include the following steps.

[0095] 501. The first client sends an operation instruction to a server in response to an operation of a user through a USB device.

[0096] Correspondingly, the server receives the operation instruction from the first client.

[0097] The detailed description of step 402 may refer to the description of step 301 .

[0098] 502. The server pre-processes the operation instruction to obtain an operation signal.

[0099] After receiving the operation instruction, the server may pre-process the operation instruction to obtain an operation signal.

[0100] The server may first parse the operation instruction to obtain the identifier of the first client and the operation data, and then pre-process the operation data to obtain the operation signal.

[0101] 503. The server sends an operation signal to the first USB conversion device.

[0102] Accordingly, the first USB conversion device receives the operation signal from the server.

[0103] The server stores a third correspondence between the USB conversion device and the processing device. The third correspondence may be as shown in Table 2 or Table 3:

[0104]

[0105] Table 2

[0106]

[0107] Table 3

[0108] Here, k is an integer greater than 1.

[0109] The server can determine the identifier of the first USB conversion device corresponding to the identifier of the first client according to the first correspondence and the third correspondence, and then send an operation signal to the first USB conversion device according to the identifier of the first USB conversion device. The first USB conversion device is the USB conversion device corresponding to the first client among the multiple USB conversion devices.

[0110] When the third corresponding relationship is as shown in Table 3, the server may send an operation signal and an identifier of the first processing device to the first USB conversion device.

[0111] 504. The first USB conversion device converts the operation signal into a USB signal.

[0112] After receiving the operation signal, the first USB may convert the operation signal into a USB signal according to the USB protocol.

[0113] 505. The first USB conversion device sends a USB signal to the first processing device.

[0114] Accordingly, the first processing device receives the USB signal from the first USB conversion device.

[0115] In the case where a USB conversion device is connected to a processing device, after the first USB conversion device converts the operation signal into a USB signal, the USB signal can be sent to the connected processing device, that is, the first processing device.

[0116] In the case where a USB conversion device is connected to two or more processing devices, the first USB conversion device is provided with a plurality of USB interfaces, each of the plurality of USB interfaces is respectively connected to a processing device. The first USB conversion device can send a USB signal to the first processing device according to the identification of the first processing device. The first USB conversion device can first determine the corresponding USB interface according to the identification of the first processing device, and then send a USB signal to the connected processing device (i.e., the first processing device) through the determined USB interface.

[0117] After receiving the USB signal, the first processing device can process the USB signal. The first processing device can trigger a CPU interrupt according to the USB signal, and then respond to the CPU interrupt and transmit the USB signal to the operating system according to the USB protocol, and the operating system processes the USB signal.

[0118] exist Figure 5 In the instruction processing method shown, the client does not send the operation instruction directly to the corresponding processing device, but first sends it to the server, which pre-processes the operation instruction to obtain an operation signal, and then sends the operation signal to the corresponding USB conversion device. The USB conversion device converts the operation signal into a USB signal and then sends it to the processing device. Since the USB signal is a hardware signal, the operating system will not affect the processing of the USB signal by the processing device, so the compatibility of the system can be improved. In addition, since the cloud desktop system uses a bare metal solution, the stability and performance of the system can be improved. Furthermore, the processing of big data is performed by the server, and the conversion of USB signals is performed by the USB conversion device, which can improve the processing efficiency of the operation instruction, thereby improving the processing efficiency of the system.
