[ first embodiment ] A method for manufacturing a semiconductor device
In the existing LED display control device, various types of signals such as video signals, audio signals, control signals, etc. are transmitted through corresponding video interfaces, audio interfaces, control interfaces, auxiliary interfaces, etc. what kind of signals need to be transmitted, and the corresponding interfaces need to be configured on the device, as shown in fig. 1, a rear panel of the device in the existing LED display industry is schematically illustrated, and the rear panel is provided with a plurality of interfaces such as a UART (Universal Asynchronous Receiver/Transmitter) interface for transmitting upper computer control instructions, an RS232 interface, a USB interface, and a control network port; an SPDIF Interface (Sony/Philips Digital Interface Sony, Philips Digital audio Interface), an analog audio Interface, and a 3D Stereo Interface for transmitting some auxiliary audio or 3D signals; an HDMI _ IN (High Definition Multimedia Interface High Definition Multimedia input Interface) Interface for transmitting data image data, an HDMI _ LOOP (High Definition Multimedia Interface High Definition Multimedia input Interface LOOP-out Interface), a DP _ IN (display port display Interface input Interface), a DP _ LOOP (display port display Interface LOOP-out Interface), an SDI _ IN (serial digital component input Interface), and an SDI _ LOOP (serial digital component serial LOOP-out Interface). And a plurality of network ports for transmitting LED screen image data. Taking the display device shown in fig. 1 as an example, the conventional display control device and signal transmission method have the following disadvantages:
(1) because the interfaces on the equipment are fixed, for example, when the number of certain interfaces needed exceeds the original design number of the equipment, only the whole set of equipment can be replaced; the use is extremely inflexible, the equipment expansibility is poor, and the cost for replacing new equipment is high.
(2) In order to reduce the above-mentioned situation that the equipment needs to be replaced, some unusual interfaces have to be preset, which results in the waste of the space of the back panel of the equipment and increases the layout difficulty of the equipment during manufacturing.
(3) Different application scenarios have different requirements for the number of different types of interfaces, and even if a plurality of interfaces are reserved, the various requirements are still difficult to meet, which is not beneficial to the batch production of equipment.
To this end, in view of the above-mentioned drawbacks of the prior art, a first embodiment of the present invention provides a signal processing system 10, as shown in fig. 7, the signal processing system 10 includes a signal processing apparatus 200 and a display screen controller 300, and as shown in fig. 5, a schematic structural diagram of a signal processing apparatus 200 according to an embodiment of the present invention is provided. Referring to fig. 7 and 5, the signal processing apparatus 200 includes: the system comprises a plurality of input interfaces 211, a target output interface 213 and a signal converter 212, wherein the input end of the signal converter 212 is connected with the plurality of input interfaces 211, and the output end is connected with the target output interface 213. The display screen controller 300 includes a target input interface 311 corresponding to the target output interface 213, and the target input interface 311 is connected to the corresponding target output interface 213 on the signal processing apparatus 200.
Wherein the signal converter 212 in the signal processing apparatus 200 is configured to execute a signal processing method M100, as shown in fig. 2, the signal processing method M100 includes the following steps:
step S1: receiving at least one path of input signals input by at least one signal input interface in a plurality of input interfaces;
step S2: respectively converting the at least one input signal into at least one conversion signal with preset interface information according to a preset conversion mode;
step S3: and transmitting the corresponding at least one path of conversion signal to a corresponding target input interface on a display screen controller through a target output interface based on the preset interface information.
The display screen controller 300 is configured to receive an input one or more switching signals through the target input interface 311, analyze the one or more switching signals based on a preset protocol comparison relationship, and output an analyzed signal. The input one or more multiplexed signals are transmitted to the target input interface 311 through a corresponding one of the target output interfaces 213 in the signal processing apparatus 200 based on the preset interface information, for example, by the above-mentioned step S3.
The plurality of input interfaces mentioned IN step S1 are the plurality of input interfaces 211 on the signal processing device 200, and may be, for example, the above-mentioned USB interfaces RS232, and the like, specifically, the signal input from one input interface 211 IN step S1 is regarded as one signal, for example, if the input signal is input from two USB interfaces respectively, then step S1 receives two input signals, for example, if the input signal is input from one RS232 interface, one SPDIF interface and one HDMI _ IN interface respectively, then step S1 receives three input signals. Of course, the type and number of the at least one input signal received in step S1 are not limited to the above examples, and each input signal type may be different or the same. It should be noted that the number of input signals received in step S1 is not completely equal to the number of input interfaces 211 on the signal processing apparatus 200, for example, four input interfaces are provided on the signal processing apparatus 200, for example, one USB interface, one RS232 interface, one UART interface and one SPDIF interface are provided, and only the USB interface and the SPDIF interface actually have signal inputs, then step S1 only receives two input signals input by the USB interface and the SPDIF interface of the plurality of input interfaces 211.
The corresponding target output interface 213 and the target input interface 311 are respectively a female terminal and a male terminal of the same type of interface, and are connected to connect the corresponding signal processing device 200 and the display screen controller 300 by matching the two, where the specific target output interface 213 is, for example, a female terminal of an RJ45(Registered Jack 45) port, and the target input interface 311 is a male terminal of an RJ45 port, and conversely, the target output interface 213 is a male terminal of an RJ45 port, and the target input interface 311 is a female terminal of an RJ45 port. Of course, the target output interface 213 and the target input interface 311 are only illustrated as an example, and the type of the two interfaces is not limited to RJ45 network interface, and may be connectors having a signal transmission function, such as PIC-e (peripheral Component Interconnect express) interface, SAS (Serial Attached SCSI) interface, and the like.
It should be noted that the signal processing apparatus 200 and the signal processing method M100 emphasize that different input signals can be converted into converted signals and then output to a corresponding target input interface 311 on the display screen controller 300 through the same target output interface 213, wherein in the signal processing apparatus 200, the target output interface 213 is not limited to the one shown in fig. 5. In some embodiments, the target output interface 213 may be one or more, and the target input interface 311 corresponding to the corresponding display screen controller 300 may also be one or more. For example, the signal processing apparatus 200 includes four interfaces disposed on the above exemplary signal processing apparatus 200, wherein the signal processing apparatus 200 converts input signals input by one USB interface and one RS232 interface into converted signals and outputs the converted signals to a corresponding one of the target input interfaces 311 on the display screen controller 300 through one of the target output interfaces 213, and also converts input signals input by one UART interface and one SPDIF interface into converted signals and outputs the converted signals to a corresponding other one of the target input interfaces 311 on the display screen controller 300 through another one of the target output interfaces 213. In this signal processing apparatus 200, two signal processing methods M100 are equivalently performed, and the contents of the two signal processing methods M100 are different. Of course, the number of the target output interfaces 213 and the target input interfaces 311 and the corresponding relationship between the plurality of input interfaces 211 are illustrated, and the embodiment is not limited thereto. For example, referring to fig. 6, the signal processing apparatus 200 is provided with two target output interfaces 213, each target output interface 213 may implement transmission of a plurality of different input signals, of course, it should not be limited to be understood that only two target output interfaces 213 are provided on the signal processing apparatus 200, and may also be three, four, or more, the types of the plurality of target output interfaces 213 may be completely the same, or may also be partially the same, or completely different, for example, the two target output interfaces 213 shown in fig. 6 may be two RJ45 interfaces, or may also be one RJ45 interface and one PCI-E interface. The present embodiment is not limited. Similarly, one or more target input interfaces 311 may be correspondingly disposed on the display screen controller 300, and each target input interface 311 may implement transmission of a plurality of different input signals.
In addition, because the transmission capabilities of different types of interfaces are different, for example, a plurality of interfaces with lower transmission capabilities on the signal processing device 200 can be selected to be one interface with higher transmission capabilities, for example, the number of pins of the RJ45 network port is smaller, and the number of pins of the PIC-E is larger, so if signals converted by the signal processing device 200 need to be transmitted through a plurality of RJ45 network ports, a plurality of RJ45 network ports can be replaced by one PIC-E interface, which makes the device more compact.
In an embodiment, the signal converter 212 is provided with a Programmable logic device, such as an FPGA (Field-Programmable Gate Array) device, for example, to execute the signal processing method M100, or may be implemented by an MCU microprocessor, which is not limited in this embodiment.
In an embodiment, the display screen controller 300 is provided with a Programmable logic device, for example, a specific Field Programmable Gate Array (FPGA) device, for performing the above analyzing process on the multiplexed signal based on a preset protocol contrast relationship, so as to obtain and output an analyzed signal, where the preset protocol contrast relationship corresponds to the target input interface 311.
In this embodiment, the signal processing apparatus 200 converts the input signals input by the plurality of input interfaces 211, so that different input signals can be transmitted to a corresponding target input interface 311 on the display screen controller 300 through the same target output interface 213, so that the display screen controller 300 can receive different input signals through the target input interface 311, thereby achieving the purpose of reducing the number of interfaces on the display screen controller 300, and simultaneously ensuring high expansibility. For example, as shown in fig. 8, another signal processing system 10 is provided for the embodiment of the present invention, wherein the signal processing apparatus 200 of the signal processing system 10 has 7 input interfaces 211, such as the RS232 interface, the control network interface, the USB interface, the UART interface, the SPDIF interface, the analog audio interface, and the 3D Stereo interface shown in fig. 8, and the signal processing apparatus 200 can convert the input signals input by the 7 input interfaces 211 into converted signals and transmit the converted signals to the target input interface 311 of the display screen controller 300 through the target output interface 213. Only one target input interface 311 is used on the display controller 300 to replace the above 7 interfaces, so that the number of the interfaces on the display controller 300 is reduced by 6 compared to the conventional display control device shown in fig. 1, and of course, the present embodiment does not limit the type and number of the input interfaces 211 in the signal processing system 10. Meanwhile, according to different use requirements, for example, when a plurality of USB interfaces are required, the signal processing apparatus 200 in the signal processing system 10 may be replaced without replacing the display screen controller 300, which is lower in replacement cost and more flexible than the existing display control apparatus.
It should be emphasized that the present embodiment also does not limit the signal processing system 10 to only one signal processing device 200 and one display screen controller 300. In order to realize the function of transmitting a plurality of different input signals by the target output interface 213, the signal processing device 200 can be flexibly used with the display controller 300.
In one embodiment, for example, the number of the signal processing apparatuses 200 is one, the signal processing apparatus 200 is provided with a plurality of target output interfaces 213, the number of the display screen controller 300 is one, and the display screen controller 300 is provided with a plurality of target input interfaces 311 respectively connected to the plurality of target output interfaces 213. For example, when the RJ45 network port is selected as the target output interface 213 and the target input interface 311, because there are fewer pins of the RJ45 network port and the transmission capability is poor, the target output interface 213 and the target input interface 311 need to be configured as a plurality of RJ45 network ports to ensure the transmission effect. It should be noted that, in the present embodiment, the effect of reducing the number of interfaces on the display screen controller 300 is only achieved when the number of input interfaces 211 of the signal processing apparatus 200 is greater than the number of target output interfaces, and when the number of input interfaces is equal to the number of target output interfaces, the effect is substantially the same as that of the existing apparatus.
In another embodiment, for example, the number of the signal processing apparatuses 200 is one, the signal processing apparatus 200 is provided with a plurality of target output interfaces 213, the number of the display screen controllers 300 is multiple, each display screen controller 300 is provided with at least one target input interface 311, and the plurality of target output interfaces 213 are respectively connected with the at least one target input interface 311 of each display screen controller 300. For example, when the resources on the signal processing apparatus 200 are sufficient, the signal processing apparatus 200 may be internally grouped, and different target output interfaces 213 correspond to different input signal combinations to meet the requirements of different display screen controllers 300. As in the above embodiments, each display screen controller 300 may be provided with one or more target input interfaces 311 according to actual requirements.
In another embodiment, for example, the number of the signal processing apparatuses 200 is plural, each signal processing apparatus 200 is provided with at least one target output interface 213, the number of the display screen controller 300 is one, and the display screen controller 300 is provided with a plurality of target input interfaces 311, wherein the plurality of target input interfaces 311 are respectively connected with the at least one target output interface 213 of each signal processing apparatus 200. As described above, for example, when the RJ45 network port is selected as the target output interface 213 and the target input interface 311, because the RJ45 network port has fewer pins and poor transmission capability, the target input interface 311 may also be configured as a plurality of RJ45 network ports to be collocated with a plurality of signal processing devices 200, compared to a scheme in which one signal processing device 200 is connected to be collocated with one display screen controller 300, the same processing effect can be achieved when a plurality of signal processing devices 200 are collocated, and when the processing requirement changes, only a corresponding part of the number of signal processing devices 200 needs to be replaced, so that the replacement cost is relatively low.
As mentioned above, in the signal processing system 10, one signal processing device 200 may be connected to one display screen controller 300, one signal processing device 200 may be connected to a plurality of display screen controllers 300, or a plurality of signal processing devices 200 may be connected to one display screen controller 300, which is not limited in this embodiment. This allows for greater flexibility and expandability.
Further, in an embodiment of the present invention, the step S2 executed by the signal converter 200 specifically includes, for example:
step S211: analyzing the at least one path of input signals respectively to obtain the protocol types corresponding to the at least one path of input signals;
step S212: converting the corresponding input signal into the converted signal having a specified protocol type based on the protocol type;
the specified protocol type is the preset interface information, and the specified protocol types corresponding to the at least one path of conversion signals are the same.
The one-path conversion signal is, for example, a multi-path conversion signal, and the step S3 specifically includes, for example:
step S31: and outputting the multiplexed signal to the target input interface in a time-sharing manner through one target output interface, wherein the specified protocol type is a communication protocol type supported by the target output interface.
In step S211, the protocol content of a certain input signal is as follows: the preamble, the defining code, and the check are used to distinguish the previous packet data from the next packet data, the device type is used to determine the type of the interface for signal input, for example, a USB interface, the protocol type is used to determine the protocol corresponding to the interface, for example, a USB2.0 protocol or a USB3.0 protocol, the data type is used to determine the input signal, for example, audio data or video data, and the like, and step S211 may obtain the protocol type corresponding to the input signal after parsing the input signal. Of course, the above is only an exemplary illustration of the input signal protocol, and the actual protocol content is not limited thereto. The designated protocol type in step S212 is the preset interface information mentioned in step S2 of the previous embodiment, so that different converted signals have the same protocol type, and in step S3, the multiplexed signals are transmitted to a corresponding target input interface 311 of the display screen controller 300 through the same target output interface 213 based on the same protocol type. The specified protocol type is a communication protocol type supported by the target output interface 213, and specifically, for example, is unified as an ethernet standard protocol, and may also be other unified custom protocols.
The display screen controller 300 analyzes the one or more converted signals based on a preset protocol comparison relationship, for example, the preset protocol comparison relationship refers to: the presets match the type of communication protocol supported by the target output interface 213. For example, if the specified protocol type of the converted signal is the ethernet standard protocol, the matching ethernet standard protocol is preset as the communication protocol type supported by the target output interface 213, and the converted signal is processed and output based on the ethernet standard protocol. The preset protocol comparison relationship is determined according to the specified protocol type converted in step S212, for example, if all the input signals are converted into the conversion signals of the a protocol in step S212, the preset protocol comparison relationship is a communication protocol type supported by the target output interface 213 matching the a protocol, and the conversion signals are processed based on the a protocol. So, no matter what kind of combination is the input signal, the homoenergetic converts different input signal into the switching signal of the same agreement type, and subsequent processing procedure display screen controller 300 also can match in target output interface 213 and switching signal through the agreement that the adaptation corresponds for signal transmission is simple and convenient more, and expansibility is strong, and the flexibility is high.
In another embodiment of the present invention, the step S2 executed by the signal converter 200 specifically includes, for example:
step S221: transmitting the at least one input signal according to a preset line respectively to obtain at least one switching signal with preset position information corresponding to the preset line respectively;
and the preset position information is the preset interface information.
Wherein, at least one of the converted signals is, for example, a multiplexed signal, and step S3 specifically includes, for example:
step S32: and simultaneously outputting the multiplexed signals to the target input interface through different pins of one target output interface.
The signal converter 212 of the signal processing device 200 has preset lines, for example, as described in step S221.
Fig. 9 is a schematic structural diagram of a signal processing apparatus 200 in this embodiment, and referring to fig. 9, the signal processing apparatus includes three input interfaces 211a, 211b, and 211c for three input signals a, b, and c, respectively, a target output interface 213 corresponds to nine pins numbered (r-n), for example, a preset connection circuit is preset in a signal converter 212, as shown in fig. 9, to connect the input interface 211a to the (r) and (b) pins of the target output interface 213, connect the input interface 211b to the (r), and (w) pins of the target output interface 213, and connect the input interface 211c to the (r), (c), and (w) interfaces of the target output interface 213, respectively. So that the input signals a, b and c are respectively transmitted according to the preset lines to obtain three switching signals corresponding to the preset lines: a conversion signal of phi to alpha, a conversion signal of phi to b and a conversion signal of phi to c. Wherein, the ((c), (c) and the ((c) () and (c) () are preset position information corresponding to the preset line. In step S32, the conversion signal (i) -a is output through the pins of the target output interface 213, the conversion signal (iv) -b is output through the pins of the target output interface 213, and the conversion signal (i) -c is output through the interfaces of the target output interface 213 (i), (ii), (iii) and (nini).
In the corresponding display screen controller 300, a protocol comparison relationship is preset, for example, position information is (first) corresponding to the protocol a, (third) corresponding to the protocol B, (fifth) corresponding to the protocol C, (sixth) corresponding to the protocol C, then according to the protocol comparison relationship, after the display screen controller 300 receives (first) -a, a conversion signal (third) -B and a conversion signal (fifth) - (seventh) input by the target input interface 311, the conversion signal (third) -a is analyzed based on the protocol a, and (sixth) -B and (seventh) are analyzed based on the protocol B, and (seventh) -C are processed based on the protocol C. The above signal processing procedure realizes the effect of outputting different input signals to the display screen controller 300 through different signal channels of the same target input interface 311, that is, the effect of reducing the number of interfaces on the display screen controller 300 is realized. And because different input signals have independent transmission channels, higher transmission speed is ensured.
Further, for example, signals to be processed by the corresponding display screen controller 300 are changed into signals d occupying four channels and signals e occupying five channels, the signal processing apparatus 200 is replaced, for example, two input interfaces are provided on the signal processing apparatus 200 and are respectively used for transmitting the input signals d and the input signals e, for example, a connecting circuit is preset in the signal converter 212 so that the two input interfaces 211 are respectively connected to pins of the target output interface 213 ((r) and ((c)) of the target output interface 213, and the input signals are converted into conversion signals ((r) -d) and (c) and ((e). And correspondingly modifying the preset protocol contrast relation in the display screen controller 300 to position information ((c) corresponds to protocol D), (c) corresponds to protocol E), (c) processes the conversion signals ((c) - (D)) based on the protocol D after the display screen controller 300 receives the two conversion signals input by the target input interface 31, and (c), (c) and (c)) processes the conversion signals ((c) - (E)) based on the protocol E. In this process, when the processing demand of display screen controller 300 changes, only need to change signal processing apparatus 200 to modify in display screen controller 300 predetermined agreement relation can, when having reduced display screen controller 300's interface quantity, still improved the expansibility, reduced the cost of change equipment, and because the positional information that each way input signal corresponds is inequality, consequently the multiplex signal can the simultaneous transmission, consequently has high-speed transmission's advantage.
Of course, the form and amount of the position information are only illustrated by way of example and not as a limitation to the present embodiment. For example, the target output interface 213 is an RJ45 network port, and has 8 pins, and 8 pins correspond to 8 different pieces of position information. Or other connectors with more pins, corresponding to more position information.
It should be noted that, in step S221, it is emphasized that each input signal has corresponding preset position information, and the signal content of the input signal is not necessarily changed after the input signal is converted into the converted signal, but may also be adjusted according to the actual situation, for example, the signal levels input from different types of interfaces are not necessarily the same, and the levels may be adjusted to match the implementation of the subsequent step.
