[ first embodiment ] A method for manufacturing a semiconductor device
Referring to fig. 1, a first embodiment of the present invention proposes an apparatus channel control method. As shown in fig. 1, the device channel control method includes, for example, steps S11 to S14.
Step S11: acquiring a plurality of channel identification codes which are respectively transmitted by the cables and respectively input from the input channels, wherein the channel identification codes are different from each other;
step S12: obtaining a channel identification code sequence based on the position sequence of the plurality of input channels, wherein the position sequence number of each of the plurality of channel identification codes in the channel identification code sequence is consistent with the position sequence number of the input channel inputting the channel identification code in the position sequence;
step S13: determining a control signal based on the channel identification code sequence; and
step S14: and responding to the control signal to control the communication relation between the output channels and the input channels.
Specifically, the device channel control method provided by the first embodiment of the present invention is suitable for being applied to a first device having a plurality of input channels and a plurality of output channels, for example, and the plurality of input channels are suitable for being connected to a second device through a plurality of cables, respectively.
In step S11, the cable is, for example, an electrical cable or an optical fiber, and the channel identification codes are unique identifiers of the corresponding input channels. For example, the channel id is, for example, serial number "1, 2, 3 …". In step S12, the channel id sequence is a sequence in which a plurality of channel ids are arranged in the order of the positions of a plurality of input channels. For example, the position sequence of the input channels is 1, 2, and 3 …, the input channels correspond to the channel identifiers, for example, "a, b, c …", and the obtained channel identifier sequence is "abcd …", that is, the position serial number of each of the mentioned channel identifiers in the mentioned channel identifier sequence is identical to the position serial number of the input channel for inputting the channel identifier in the position sequence. Step S13 includes, for example: and automatically searching a control code corresponding to the channel identification code sequence from a control code table based on the channel identification code sequence to obtain the control signal. The control code table is mainly composed of a channel identification code sequence and corresponding control codes, and each control code is unique, namely, the control codes are different.
For better understanding of the present embodiment, a specific implementation of the device channel control method provided in the present embodiment is described below with reference to fig. 2 to 4.
As shown in fig. 2, device a has four output channels, output channel 1, output channel 2, output channel 3, and output channel 4. Device B has four input channels, input channel 1, input channel 2, input channel 3, and input channel 4. It is now necessary to cascade two devices, i.e. to cascade device a and device B with 4 cables, e.g. optical fibers, to form 4 communication channels. In the prior art, when a user uses optical fibers to cascade device a and device B, each optical fiber needs to connect a corresponding channel, that is, output channel 1 of device a connects input channel 1 of device B, output channel 2 of device a connects input channel 2 of device B, output channel 3 of device a connects input channel 3 of device B, and output channel 4 of device a connects input channel 4 of device B. The device channel control method provided by the first embodiment of the present invention does not need to care whether the respective channels of the two devices are connected correspondingly, and only needs to ensure reliable connection of optical fibers. For example, as shown in FIG. 2, the user connects output channel 1 of device A to input channel 2 of device B, output channel 2 of device A to input channel 1 of device B, output channel 3 of device A to input channel 3 of device B, and output channel 4 of device A to input channel 4 of device B.
After the two devices are connected, firstly, the device a sends channel identification codes through 4 connected channels, the channel identification codes are 1, 2, 3 and 4 respectively, that is, the output channel 1 of the device a sends the channel identification code 1 to the input channel 2 of the device B through an optical fiber, the output channel 2 of the device a sends the channel identification code 2 to the input channel 1 of the device B through the optical fiber, the output channel 3 of the device a sends the channel identification code 3 to the input channel 3 of the device B through the optical fiber, and the output channel 4 of the device a sends the channel identification code 4 to the input channel 4 of the device B through the optical fiber. The device B obtains a plurality of channel identification codes sent by the device a to obtain a sequence of channel identification codes. If the channel id sequence obtained by device B is 1234, it indicates that the connection sequence of the two devices is correct, and no adjustment is needed. If the channel id code sequence obtained by device B is not 1234, it indicates that the two devices are not connected in the correct order. According to the foregoing connection manner, the channel identifier sequence obtained by the device B is 2134. At this time, the device B searches for the control code 00001 corresponding to the channel identification code sequence 2134 from the control code table shown in table 1 to obtain a corresponding control signal, and the device B controls the communication relationship between the four input channels of the device B and the four output channels of the device B according to the corresponding control information, that is, the input channel 1 of the device B is communicated with the output channel 2 of the device B, the input channel 2 of the device B is communicated with the output channel 1 of the device B, the input channel 3 of the device B is communicated with the output channel 3 of the device B, and the input channel 4 of the device B is communicated with the output channel 4 of the device B. It should be noted here that the output channels 1 to 4 in the device B are not necessarily the final data output channels of the device B, but may also be data input channels of some processing modules in the device B.
TABLE 1 control coding table
| Control coding | Channel identification code sequence |
| 00000 | 1234 |
| 00001 | 2134 |
| 00010 | 1243 |
| … | … |
| 11111 | 4321 |
Further, as shown in fig. 3, a 4-in-4-out MUX (multiplexer) is provided in the device B, for example, and is configured to control the communication relationship between the plurality of output channels and the plurality of input channels of the device B in response to the control signal. As shown in fig. 4, both ends of the MUX are provided with 4 interfaces, the interface disposed at the left end of the MUX corresponds to four input channels of the connection device B, and the interface disposed at the right end of the MUX corresponds to four output channels of the connection device B. The channel identifier code sequence output by the right end of the MUX is always unchanged, which is 1234. There are 24 choices in the channel identification code sequence input at the left end of the MUX, which can adapt to all possible cases of wrong connection in this embodiment. In addition, the MUX also has a control terminal (SEL) which adopts a coding mode to indicate that the control coding adopts 5 bits because the channel identification code sequence has 24 choices. The MUX searches the corresponding control code 00001 from the control code table shown in table 1 according to the channel identification code sequence 2134 obtained by the erroneous connection between the two devices, and then generates a control signal to adjust the communication relationship between the input and the output of the device B, so that the output at the right end of the MUX in the device B is the output in a fixed sequence, namely 1234.
It should be noted that the control code table shown in table 1 does not limit the correspondence between the channel identifier sequences and the control codes, that is, the control code corresponding to each channel identifier sequence can be adjusted according to the user requirement, for example, the channel identifier sequence 2134 may also correspond to the control code 00010. In addition, in the specific implementation manner of this embodiment, four channels are taken as an example to illustrate, and accordingly, the number of the control encoding bits is 5 bits, but the present invention is not limited thereto, and the number of the channels may be increased or decreased according to the user requirement, and the number of the corresponding control encoding bits is also increased or decreased.
In addition, the device channel control method provided by the embodiment can be applied to products such as a video processor, a video input source expander, an adaptor in the communication field and the like.
In summary, the device channel control method provided in the first embodiment of the present invention avoids the tedious steps that cables need to be connected in sequence one-to-one before the devices are used, avoids the problems of communication interruption or abnormality between the devices due to a wrong cable connection sequence, and the like, can implement readjustment of the connectivity inside the devices, achieves an effect of adapting to the wrong cable connection sequence, and a user does not need to care whether the connection sequence of the cables is correct, but only needs to ensure reliable connection of the cables, thereby improving the usability of the devices.
