Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In practical applications, the subsequent display module usually needs to process different input sizes with different widths and heights and different output resolution information, when the data amount of the input video frame information is large, a relatively high clock is usually required to read data from the DDR, and when the output resolution or the frame rate is high, the requirement for the pixel clock is also higher. If a higher clock is used in software design to read a video frame with a smaller data size, the video frame can be displayed and output normally functionally, but the display power consumption is increased compared with a reasonable clock configuration.
The rear-stage display module generally needs to process compressed data and uncompressed data, the path is also divided into a compressed path and an uncompressed path, the HDR module is also processed in the 4K set-top box, and the common path also has scaling modules at all stages and modules for writing back a memory, and if the paths at all stages are enabled no matter the scene requirements are met, the rear-stage display module works equivalently, the load is quite large, and the display power consumption is greatly increased.
In order to solve the above problems, the present application provides a control method for a rear-stage display module, which reconfigures the rear-stage display module according to an actual source configuration parameter and an output configuration parameter of a video to be output, only enables a required working circuit, and closes other irrelevant circuit units, thereby satisfying a user display requirement, reducing the total power consumption of the rear-stage display module, reducing the resource occupation, and improving the chip life of the rear-stage display module.
The embodiment of the invention discloses a control method of a rear-stage display module, which is shown in figure 1 and comprises the following steps:
s1: acquiring source configuration parameters of a video to be output;
s2: acquiring a user configuration instruction or an output configuration parameter corresponding to output equipment;
s3: in the rear-stage display module, determining a working circuit unit corresponding to the source configuration parameter and/or the output configuration parameter;
s4: enabling the working circuit unit and closing other circuit units in the rear-stage display module, which are similar to the working circuit unit.
It can be understood that the purpose of this embodiment is to dynamically control the operating states of the circuit units in the rear-stage display module, only enable the relevant operating circuit units, and close other circuit units that are similar to the operating circuit units and do not participate in the display operation, thereby reducing the total power consumption of the rear-stage display module while ensuring that the video to be output can be displayed according to the corresponding configuration.
Specifically, as shown in fig. 2, the path of the video to be output in the rear-stage display module generally includes: the decoder decodes the video to be output to obtain frame data, the frame data passes through a certain data analysis output unit, then is processed by an HDR unit, is processed by a pre-scaling unit, then enters a certain memory dynamic control unit, then passes through a plurality of image processing units in sequence, and finally is output by a display output terminal. The data analysis output unit comprises a compression unit and a non-compression unit, wherein the non-compression unit comprises an interlaced unit and a progressive unit; the pre-scaling unit can reduce the size of the frame data but cannot enlarge the frame data; the memory dynamic control unit comprises a write-back unit and a non-write-back unit, and also comprises a memory release unit; the image processing unit specifically comprises an image scaling unit, an image effect unit and the like; the display output terminal includes an HDMI output terminal and/or a CVBS output terminal.
In the prior art, no matter whether the video is in a path of frame data of a video to be output or not, all units existing in the rear-stage display module are in an enabling state and run by using the highest working clock, so that the power consumption of the rear-stage display module is higher and waste is caused.
Specifically, the step S3 is a process of determining a working circuit unit corresponding to the source configuration parameter and/or the output configuration parameter in the rear-stage display module, and includes:
in the rear-stage display module, determining a display output terminal corresponding to the output configuration parameter;
and/or, in the rear-stage display module, determining the source configuration parameters and the working clocks corresponding to the output configuration parameters;
and/or determining a data analysis output unit corresponding to the source configuration parameter in a rear-stage display module;
and/or determining a memory dynamic control unit corresponding to the source configuration parameter and the output configuration parameter in the rear-stage display module.
It is understood that the circuit units involved in the present embodiment may be classified into display output terminals, operating clocks, data analysis output units, memory dynamic control units, etc. according to general categories, and when the subsequent display module may further include other types of circuit units, there is no specific limitation here. Step S3 is to determine a specific one or more working circuit units in each type of circuit unit, and other circuit units of the same type can be turned off when the video to be output is displayed, so as to avoid resource waste and redundant power consumption.
The embodiment of the application discloses a control method of a rear-stage display module, which comprises the following steps: acquiring source configuration parameters of a video to be output; acquiring a user configuration instruction or an output configuration parameter corresponding to output equipment; in a rear-stage display module, determining a working circuit unit corresponding to the source configuration parameter and/or the output configuration parameter; enabling the working circuit unit and closing other circuit units which are similar to the working circuit unit in the rear-stage display module. According to the method and the device, the rear-stage display module is reconfigured according to the actual source configuration parameters and the output configuration parameters of the video to be output, only the required working circuit is enabled, and other irrelevant circuit units are closed, so that the user display requirements are met, the total power consumption of the rear-stage display module is reduced, the resource occupation is reduced, and the chip life of the rear-stage display module is prolonged.
The embodiment of the invention discloses a specific control method of a rear-stage display module, and compared with the previous embodiment, the embodiment further explains and optimizes the technical scheme. Specifically, the method comprises the following steps:
in the rear-stage display module, the process of determining the display output terminal corresponding to the output configuration parameter specifically includes:
and determining that the display output terminal in the rear-stage display module is specifically an HDMI output terminal or a CVBS output terminal according to the display output terminal parameter of the output configuration parameter.
It can be understood that, according to a display output terminal parameter in an output configuration parameter of an output device, that is, a display device, a display output terminal supported by the output device may be obtained, and the type of the display output terminal may specifically include an HDMI output terminal and/or a CVBS output terminal; according to the display output terminal parameters in the output configuration parameters of the user configuration instruction, the display output terminal corresponding to the user configuration instruction can be obtained, and the type of the display output terminal can specifically include an HDMI output terminal and/or a CVBS output terminal. The display output terminal parameters supported by the output equipment are higher in priority, the plurality of display output terminals correspond to different priorities, the display output terminal parameters of the output equipment and the display output terminal parameters of the user configuration instruction are compared, when intersection exists, if the intersection corresponds to a unique display output terminal, the display output terminal corresponding to the intersection is directly determined, if the intersection comprises the plurality of display output terminals, the display output terminal with the higher priority is selected according to default setting of a system, and when the intersection does not exist, the display output terminal parameters of the output equipment are taken as the standard. Further, after the display output terminal is determined, the display output terminal is enabled, and if other display output terminals exist in the display device, other display output terminals in the display device are closed.
Wherein, in the rear-stage display module, the process of determining the source configuration parameters and the working clocks corresponding to the output configuration parameters comprises the following steps:
and determining the level of a working clock in the rear-stage display module according to the frame data information in the source configuration parameters and the output resolution information in the output configuration parameters.
Wherein, the frame data information in the source configuration parameters comprises the frame size, the frame rate, the data format and other information of the video to be output, selecting corresponding display channels, namely frame data transmission channels, according to the frame data information and the output resolution information, wherein each display channel can calculate the working clock with the lowest frequency allowing each working circuit unit to work according to the hardware parameters, the frame data information and the output resolution information in the rear-stage display module, specifically comprises the corresponding top/sram/mcm clock, besides, the working clocks under different configuration conditions can also be stored in a table form after being calculated and set in advance, for example, the clock calculated for the video to be output of 4K is 345MHz, the clock calculated for the video to be output of FHD is 196MHz, when the specific control method is applied, the level of the working clock required by each working circuit unit under the current condition can be determined only by looking up the table. Further, after the level of the operating clock is determined, the operating clock of the level is enabled, and the circuit units of the clocks of other levels are turned off. Compared with reading data by the maximum clock, the accurate working clock consumes less power on the premise of meeting the display function. The process of determining the data analysis output unit corresponding to the source configuration parameter in the rear-stage display module includes:
analyzing frame data information in the source configuration parameters, and determining the type of the frame data information;
when the frame data information is compressed data, determining a data analysis output unit as a compression unit;
when the frame data information is non-compressed data and is interlaced data, determining that the data analysis output unit is an interlaced unit;
and when the frame data information is non-compressed data and non-interlaced data, determining the data analysis output unit as a progressive unit.
It can be understood that, frame data information is different, data analysis output units required by the frame data information are also different, all data analysis output units in the previous rear-stage display module are enabled, but only one data analysis output unit is in a working state, and other working circuit units are only wasting resources, so that in the embodiment, on the premise of considering dynamic reduction of power consumption, the data analysis output unit corresponding to the frame data information is determined, so that other data analysis output units except the data analysis output unit are closed, specifically, if the data analysis output unit is determined to be a compression unit, only the compression unit is enabled, and similar interlaced units and progressive units are closed; if the data analysis output unit is determined to be an interlaced unit, only the interlaced unit is enabled, and the compression unit and the progressive unit of the same type are closed; and if the data analysis output unit is determined to be a progressive unit, only the progressive unit is enabled, and the similar interlaced unit and the similar compression unit are closed, so that effective power consumption limitation is realized.
Generally, frame data information is processed by a specific data analysis output unit, then sent to an HDR unit for processing, then sent to an image processing unit such as a scaler for processing, and finally output to a display output terminal. It is understood that if the HDR processing is also supported inside the output device, the HDR unit may be skipped in the rear-stage display module of the present embodiment, thereby saving power consumption of the HDR unit in the rear-stage display module. Similarly, the control method of the embodiment may further consider whether the frame data information must pass through the pre-scaling unit and/or the image effect unit, and if not, may skip unnecessary circuit units to reduce power consumption and access times to the DDR.
Similarly, referring to fig. 3, in the post-stage display module, the process of determining the dynamic memory control unit corresponding to the source configuration parameter and the output configuration parameter specifically includes:
s11: determining the scaling ratio of the video to be output according to the video input size in the source configuration parameters and the video output size in the output configuration parameters;
s12: judging whether the video to be output needs to be written back to the memory according to the scaling ratio;
s13: if yes, determining the memory dynamic control unit as a write-back unit;
s14: if not, the dynamic memory control unit is determined to be a non-write-back unit.
In order to further reduce resource consumption, after determining that the dynamic memory control unit is a write-back unit, the method further includes: and enabling the memory release unit to release the memory applied during offline or the memory corresponding to the resource to be destroyed.
It can be understood that, when the dynamic memory control unit is determined to be a write-back unit, the write-back unit and the memory release unit are enabled, and the non-write-back unit is closed; and when the dynamic memory control unit is determined to be a non-write-back unit, enabling the non-write-back unit, and closing the write-back unit and the memory release unit.
It can be understood that the determination of the dynamic memory control unit corresponds to a dynamic adjustment policy of the later-stage display module regarding memory power consumption, as shown in fig. 4, the policy specifically includes:
and the rear-stage display module receives the frame data of the front-stage module and the output coordinate information set by a user to obtain the input and output size and the zoom ratio, determines whether to use the write-back unit or the non-write-back unit to dynamically apply for the memory to process according to the zoom ratio, and dynamically determines whether to release the memory after display and output. Data is enabled to go on line mode as much as possible and is processed by a non-write-back unit, and the application of memory on a zooming path is avoided; when the scaling path is required to go through an offline mode for data write-back, the memory is applied according to the frame size of actual scaling write-back, so that the situation that the maximum memory is directly applied is avoided, resource waste is avoided, and the maximum memory is processed by a write-back unit; in the scene switching process of practical application, when the data on the display path is converted from the offline mode to the online mode, the memory release unit releases the memory applied in the last offline mode, and the memory is dynamically recycled; when the data on the zooming channel is applied for the memory in an off-line mode, if the system resources are insufficient, the required write-back memory cannot be applied, and the write-back strategy can be dynamically adjusted to meet the data requirement; similarly, in the software implementation of the rear-stage display module, a part of resource management may be involved, such as management of a queue or a thread, and also an application of a resource memory may be involved.
