detailed description

The embodiments of the present application provide an information processing method and an electronic device to solve the technical problem of the single function of the I/O interface existing in the prior art.

The technical solution in the embodiment of the present application is to solve the problem of the single technology of the I/O interface function existing above, and the general idea is as follows:

By establishing a data channel between the first interface and the second chip, the first data signal obtained through the first interface and generated by the external electronic device connected to the electronic device can be transmitted to the second chip and be responded by the second chip The processing is to control the electronic device to realize the first function, and further realize the function multiplexing of the first interface.

In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

The present application and an embodiment provide a method for information processing, which is applied to an electronic device. As shown in FIG. 2, the electronic device includes: a circuit board 10; support the first protocol; the second chip 30, for example, SIO, is arranged on the circuit board 10, and a data channel can be established between the first interface 10; the control chip 40, for example, BIOS (Basic Input Output System, basically The input/output system) chip is connected between the first interface 20 on the circuit board 10 and the second chip 30 . Of course, the first interface 20, the second chip 30 and the control chip 40 can also be one or more other interfaces and chips, which can be set by those skilled in the art, and this application does not make specific limitations.

As shown in Figure 1, the method includes:

S101: Obtain a first data signal from the first interface 20, where the first data signal is generated by an electronic device connected to the electronic device through the first interface 20;

S102: Based on a data channel between the first interface 20 and the second chip 30, transmit the first data signal to the second chip 30;

S103: When the first data signal satisfies the first preset condition, control the second chip 30 to respond to the first data signal, so as to realize the first function of the electronic device.

The above technical solution will be described below by taking the keyboard/mouse to control the startup of the electronic device as an example.

Please combine Figure 3a, for example, the user needs to use the keyboard to control the desktop computer to power on and start, then, first, the user connects the keyboard to the computer through the USB interface on the computer, and then presses the power button set on the keyboard, such as "power key", at this time, the keyboard will send this control command to the USB interface on the keyboard, and then connect this interface with the first interface 20 on the computer, execute S101, and the computer can obtain the first data signal, according to the USB protocol, the first data signal may include attribute information of the electronic device sending the first data signal, such as device name, model, and so on.

In a specific implementation process, the first data signal may also be sent by other USB devices, such as a mouse. Then, when the user needs to start the mouse, connect the mouse to the computer through the USB interface on the computer, and then the user can click the mouse button, such as double-clicking the left button, to generate a power-on command, and then the power-on command will be the same as the above-mentioned keyboard power-on. transmitted to the first interface 20.

Of course, the electronic device connected to the computer through the USB interface is not necessarily a keyboard/mouse, and may also be a USB flash drive or a mobile phone. Then, at this time, these electronic devices are not boot commands. A data signal may also be other signals, for example, a U disk connection, which is not specifically limited in this application.

Next, after obtaining the first data signal in S101 , execute S102 , that is, transmit the first data signal to the second chip 30 based on a data channel between the first interface 20 and the second chip 30 .

In a specific implementation process, as shown in FIG. 3a, the electronic device further includes: a switch unit 50, which may be a single-pole double-throw switch, or an electronic switch; a first chip 60, which supports the first protocol, such as a USB control chip. Of course, the first chip 60 may also be other chips, as long as it is a corresponding control chip of the first interface 20, which is not specifically limited in this application. Then, before S102, the method further includes: judging whether the first data signal is a data signal satisfying the second preset condition; when the first data signal satisfies the second preset condition, controlling the switch unit 50 to switch the second An interface 20 is connected to the second chip 30 such that a data channel is established between the first interface 20 and the second chip 30 .

Specifically, as mentioned above, the first data signal is not limited to a power-on command, and it is not necessarily sent by the keyboard, so before establishing the data channel, it is necessary to judge the received first data signal to determine whether it satisfies the Second preset condition. For example, when the second preset condition is that the first data signal is a data signal sent by the keyboard, first, the first interface 20 will transmit the first data signal to the control chip 40, and then, the control chip 40 judges the first data signal When the signal meets the above preset conditions, the control chip 40 will control the switch unit 50 to connect the first interface 20 and the second chip 30 to establish a data channel between the two. Certainly, the second preset condition may also be that the first data signal is a data signal sent by a mouse, which is not specifically limited in this application.

Further, in order not to affect the normal operation of other USB devices, for example, when a U disk is connected to the first interface 20, in order to allow the U disk to be used normally, the method also includes: when the first data signal does not satisfy During the second preset condition, the switch unit 50 is controlled to connect the first interface 20 with the first chip 60 supporting the first protocol, so that a data channel is established between the first interface 20 and the first chip 60; output to the first chip 60.

Specifically, if the U disk is connected to the computer through the first interface 20, then the first data signal generated by the U disk does not meet the second preset condition, and the control chip 40 will switch the switch unit 50 to the first data signal. The chip 60 is connected, and then outputs the first data signal to the first chip 60 .

The third step is to execute S103, that is, when the first data signal satisfies the first preset condition, control the second chip 30 to respond to the first data signal, so as to realize the first function of the electronic device. The first preset condition mentioned here can be that the first data signal is a data signal that the second chip 30 can respond to, of course, it can also be one or more other conditions, as long as the second chip 30 can realize the first function That is, the present application does not make a specific limitation.

In a specific implementation process, S103 may be: when the first data signal satisfies the first preset condition, control the second chip 30 to generate a control instruction in response to the first data signal; execute the control instruction to control the first function of the electronic device. In this embodiment, the first function is the keyboard/mouse to control the power-on and start-up of the electronic equipment. Of course, in the specific implementation process, the first function can also be the keyboard or mouse input function, as long as the first function is that the second chip 30 can respond The realized functions are sufficient, and are not specifically limited in this application.

Specifically, after the data channel is established between the first interface 20 and the second chip 30, the control chip 40 will further judge whether the first data signal satisfies the above-mentioned first preset condition. When setting the condition, the control chip 40 analyzes the first data signal, and generates a signal that the second chip can respond to, and then transmits it to the second chip 30, and then, the second chip 30 generates a control instruction according to the signal, such as , the first data signal is a power-on signal, then the second chip 30 will generate a power-on control command, and then, the second chip 30 executes the power-on control command to control the power-on of the electronic device.

In another embodiment, as shown in FIG. 3 b , the electronic device further includes: a first chip 60 . Connect the first interface 20 to the first chip 60 and the second chip 30 respectively, so that both the first chip 60 and the second chip 30 can receive the first data signal output by the first interface 20 . Such a hardware connection structure makes the hardware structure of the electronic device simple, and the signal is directly transmitted to the processing chip, thus improving the response efficiency of the chip to the external electronic device. At this time, S102 may be: respectively output the first data signal to the first chip 60 and the second chip 30 supporting the first protocol; when the first chip 60 receives the first data signal, the first chip 60 does not respond to the first chip 60 a data signal.

Specifically, when the first data signal is a power-on signal, the first interface 20 sends this signal to the first chip 60 and the second chip 30 at the same time, because the first chip 60 does not support the function of keyboard power-on, so it cannot Respond to the first data signal; and since the data channel between the first interface 20 and the second chip 30 has been established, the control chip only needs to analyze the first data signal into a signal that the second chip 30 can respond to, and transmit it to the The second chip 30, and the second chip 30 responds.

Applying the above method to control the startup of the electronic device can enable the first data signal transmitted to the electronic device through the first interface 20 to be responded by the second chip 30, and then control the startup of the electronic device, so that the USB that does not originally support keyboard/mouse startup The interface can realize this function and realize the function multiplexing of the USB interface; and after the electronic device is powered on, the control chip 40 also controls the switch unit 50 to communicate with the first interface 20 and the first chip 60, that is to say, the switch The unit 50 is switched to the first chip 60, so that other electronic devices can work normally; further, since the first interface 20 is respectively connected to the first chip 60 and the second chip 30, the first data signal can be transmitted to the above two The chip, in this way, reduces the complexity of the hardware of the electronic device, and also improves the response efficiency of the chip because of the parallel transmission of signals.

The above-mentioned technical solutions in the embodiments of the present application have at least the following technical effects or advantages:

1. Since the first data signal is transmitted to the second chip through the data channel between the first interface and the second chip, the second chip can respond to the signal to realize the first function, so it effectively solves the problem of the prior art The technical problem of the single function of the I/O interface in the system is solved, and then the function reuse of the interface is realized.

2. Since the first interface is respectively connected to the first chip and the second chip, the first data signal can be directly transmitted to the above two chips, thus reducing the complexity of the hardware of the electronic device and improving the efficiency of the signal due to the parallel transmission of signals. The response efficiency of the chip is improved.

Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and equivalent technologies thereof, the present invention also intends to include these modifications and variations.
