Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, 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 application.
Currently, disabling certain functions and replacing components in the equipment can affect the stable operation of the equipment. The replacement of the device also increases the cost, the replacement operation is generally complicated, and the implementation process has certain difficulty. Therefore, the bus bandwidth use peak value adjusting scheme is provided, bus bandwidth resources in hardware equipment can be balanced, stable operation of the hardware equipment is guaranteed, and operation complexity and cost are reduced.
Referring to fig. 1, an embodiment of the present application discloses a first method for adjusting a peak value of bandwidth usage of a bus, including:
s101, receiving an instruction for adjusting bus bandwidth occupied by an image processing process;
s102, adjusting color parameters of a frame buffer memory according to the instruction;
wherein the color parameters include: the data volume occupied by each pixel point, the position and size of each color in the data volume, and the length of each line of image data. And after the color parameters are adjusted in the application layer, the color parameters are transmitted to the kernel of the equipment, and the kernel can control the driving of the equipment to complete the configuration of the color parameters. After the driver obtains the color parameters, firstly, judging whether the actually configured color parameters in the current equipment are consistent with the color parameters which are newly obtained currently; if the two are consistent, no operation is performed; and if the color parameters are not consistent, configuring the color parameters.
In one embodiment, adjusting the color parameters of the frame buffer memory according to the instruction comprises: adjusting the data volume occupied by each pixel point to a target value according to the instruction; the position and size of each color in the target value, and the length of each line of image data are adjusted.
The length of each line of image data can be obtained by calculation based on the resolution of the equipment and the data volume occupied by one pixel point, and the calculation formula is as follows:
fb_fix_screeninfo->line_length＝(fb_var_screeninfo->xres_virtual*(fb_var_screeninfo->bits_per_pixel/8)+31)&0xFFFFFFE0。
the number of bytes of each line of image data W is equal to the number of pixels occupied by each line of data x the number of bytes occupied by each pixel. Wherein, the number of bytes occupied by each pixel point is equal to the number of bits occupied by each pixel point divided by 8. After that, W is aligned with 32 bytes, so that line _ length can be obtained.
Wherein line _ length is the length of each line of image data. The device resolution is the resolution of the display screen of the device.
For example: the data volume occupied by each pixel point is adjusted from 16 bits (bit) to 8 bits, and then the position and size of each corresponding color in the 8 bits are adjusted as follows: the offset amount of red, green, blue, transparency in the 8-bit data is 0, and the length occupied by red, green, blue, transparency in the 8-bit data is 0, which are all provided in the structural body fb _ var _ screen.
The color parameter adjustment code may be:
bit _ per _ pixel is 8; // 8 bits per pixel
red, offset is 0; // red offset 0 in 8bit data
Length is 0; // red length of 8bit data
red.msb_right＝0；
Offset is 0 in green; offset 0 of/green in 8bit data
green.length＝0；
green.msb_right＝0；
Offset is 0; // blue offset 0 in 8bit data
blue.length＝0；
blue.msb_right＝0；
Offset is 0; // transparency offset 0 in 8bit data
transp.length＝0；
transp.msb_right＝0。
If the color format of the image is converted from CLUT _8BPP to RGB565, the corresponding adjustment code may be:
bit _ per _ pixel 16; // 16 bits per pixel
red. offset is 11; // red offset in 16bit data 11
Length 5; // red occupies 16bit data of length 5
red.msb_right＝0；
Offset 5, green; offset 5/green in 16bit data
Length 6; the length occupied by/green in 16bit data is 6
green.msb_right＝0；
Offset is 0; // blue offset 0 in 16bit data
Length 5; // blue occupies 16bit data with a length of 5
blue.msb_right＝0；
transp.offset＝0；
transp.length＝0；
transp.msb_right＝0。
The interconversion between other formats can be found in the above mentioned adaptation code implementation.
It should be noted that, the data amount occupied by each pixel is adjusted from 16 bits to 8 bits, which is to substantially convert the color format of the image from RGB565 to CLUT _8 BPP. The color format related to the present embodiment includes CLUT _8BPP, CLUT _4BPP, CLUT _2BPP, CLUT _1BPP, RGB565, and the like. Of course, the data size occupied by each pixel point can be adjusted to be larger, such as: 24bit, 32bit, etc. The larger the data volume occupied by one pixel point is, the clearer the image display is, but the larger the data volume in the image processing process is.
In the color format of RGB565, each pixel occupies 16 bits, wherein Red occupies 5 bits, Green occupies 6 bits, and Blue occupies 5 bits. 255 colors correspond to CLUT _8BPP, and CLUT _4BPP, CLUT _2BPP, CLUT _1BPP, and the like are also formats that occupy less data than CLUT _8 BPP.
In the color format of CLUT _8BPP, each pixel occupies 4 bits and can represent 256 colors; in the color format of CLUT _4BPP, each pixel occupies 4 bits and can represent 16 colors; in the color format of CLUT _2BPP, each pixel occupies 4 bits and can represent 4 colors; in the color format of CLUT _1BPP, each pixel occupies 4 bits, and can represent 2 colors.
S103, adjusting configuration parameters of the image processing module according to the color parameters;
wherein, the configuration parameters comprise: the color format corresponding to the color parameter and the storage position of the data in the color format in the processing process.
As described above, different color parameters correspond to different color formats, and during the data processing process, the storage location of the data in the memory needs to be determined, so as to facilitate the display of the data. Therefore, the storage position of the data in the color format in the processing process is as follows: on which memory area the data is stored. One frame buffer memory can correspond to two memory areas, and the two memory areas alternately receive the image data transmitted by the frame buffer memory. The frame buffer memory and the memory area are both memories in the device.
And S104, processing the image transmitted to the frame buffer memory by using the adjusted color parameters and the adjusted configuration parameters so as to adjust the bus bandwidth occupied by the image processing process.
The frame buffer memory, the image processing module and the bus are devices in the same equipment. The image processing module is provided with a DSP chip, and the maximum data volume occupied by one pixel point which can be supported by the device can be determined through the DSP chip.
In this embodiment, before receiving the instruction for adjusting the bus bandwidth occupied by the image processing process, the method further includes: the device is started and color parameters and configuration parameters are initialized. Wherein initializing color parameters comprises: color parameters are initialized according to the maximum value supported by the image processing module. The maximum value supported by the image processing module is the maximum data volume occupied by one pixel point supported by the current equipment. If the maximum value supported by the current equipment is 32 bits, color parameters are initialized to be 32 bits occupied by each pixel point, and other related parameters are set accordingly. Of course, if the requirement for the definition of image display is not high in the using process of the device, the color parameters can be initialized to be that each pixel point occupies 16 bits, 8 bits and the like, and other related parameters are set accordingly. Before receiving an instruction for adjusting the bus bandwidth occupied by the image processing process, the method further includes: the spatial size of the frame buffer memory is initialized to be maximized.
It should be noted that, when the device processes an image, the bus bandwidth occupied by the image processing process is generally large, so that the bus bandwidth occupied by the image processing process is reduced, and sufficient bus bandwidth resources can be provided for other functions; the bus bandwidth occupied by the image processing process is increased, the definition of image display can be improved, and further the user experience is improved. The "adjustment" described in this embodiment means "decrease" or "increase".
Therefore, after receiving the instruction for adjusting the bus bandwidth occupied by the image processing process, the embodiment of the application adjusts the color parameters of the frame buffer memory according to the instruction, adjusts the configuration parameters of the image processing module according to the color parameters, and further processes the image transmitted to the frame buffer memory by using the adjusted color parameters and the adjusted configuration parameters, so that the bus bandwidth occupied by the image processing process is adjusted, and the adjustment of the bandwidth occupied by the image processing process is realized. According to the method provided by the application, the bandwidth occupation amount of the equipment in the image processing process can be adjusted. When the bus bandwidth occupation in the hardware equipment is low, the bandwidth occupation in the image processing process can be increased; when the bus bandwidth occupation in the hardware equipment is high, the bandwidth occupation in the image processing process can be reduced. The method and the device adjust the bus bandwidth occupied in the image processing process in real time according to the needs, thereby balancing the bus bandwidth resources in the hardware equipment and ensuring the stable operation of the hardware equipment. The method does not need to replace devices in the equipment, and reduces the operation complexity and cost.
Referring to fig. 2, an embodiment of the present application discloses a second method for adjusting a peak value of bandwidth usage of a bus, including:
s201, receiving an instruction for adjusting bus bandwidth occupied by an image processing process;
s202, adjusting color parameters of a frame buffer memory according to the instruction;
wherein the color parameters include: the data volume occupied by each pixel point, the position and size of each color in the data volume, and the length of each line of image data.
S203, adjusting configuration parameters of the image processing module according to the color parameters;
wherein, the configuration parameters comprise: the storage position of the data in the color format in the processing process;
s204, acquiring an image to be processed;
s205, converting the image into a target format, and transmitting the image in the target format to a frame buffer memory;
the target format may be RGB565, CLUT _8BPP, etc. Generally, a device needs to convert a compressed JPEG, TIFF, RAW, or the like format into a recognizable and processable color format before processing an image.
S206, the frame buffer memory reads the image according to the color parameters and transmits the read image to the image processing module, so that the image processing module processes the image according to the configuration parameters to adjust the bus bandwidth occupied by the image processing process.
The frame buffer memory, the image processing module and the bus are devices in the same equipment.
In a specific embodiment, the trigger condition of the instruction for adjusting the bus bandwidth occupied by the image processing process may be an operation of a user on the device interactive interface. If the device is a smart phone, the operation of opening the camera of the smart phone by the user may be a trigger condition of the instruction. Specifically, when the smart phone obtains an operation of opening a camera by a user, the page is switched to a shooting state, at the moment, an interactive interface of the smart phone displays a picture to be shot or a video to be recorded, at the moment, the definition requirement of the user on the picture and the video is very high, and other control buttons displayed in the page can display a fuzzy point. Wherein the photo and other control buttons in the current page belong to different picture layers, so that the display effect can be processed separately.
Of course, the trigger condition of the instruction to adjust the bus bandwidth occupied by the image processing process may also be a peak occupancy value and a valley occupancy value of the bus bandwidth in the device. The method comprises the steps of presetting an occupied amount peak value and an occupied amount valley value of the bus bandwidth, wherein the occupied amount peak value is larger than the occupied amount valley value. When the actual occupied amount of the bus bandwidth is larger than the occupied amount peak value, the fact that the current equipment bus is busy is indicated, and an instruction for adjusting the bus bandwidth occupied in the image processing process can be triggered, so that the actual occupied amount of the bus bandwidth is reduced. When the actual occupied amount of the bus bandwidth is smaller than the occupied amount valley value, the current equipment bus is indicated to be idle, and an instruction for adjusting the bus bandwidth occupied in the image processing process can be triggered to increase the actual occupied amount of the bus bandwidth.
It should be noted that other implementation steps in this embodiment are the same as or similar to those in the above embodiment, and therefore, the description of this embodiment is omitted here.
As can be seen from the above, in this embodiment, after receiving the instruction for adjusting the bus bandwidth occupied by the image processing process, the color parameter of the frame buffer memory is adjusted according to the instruction, the configuration parameter of the image processing module is adjusted according to the color parameter, and the image transmitted to the frame buffer memory is processed by using the adjusted color parameter and the adjusted configuration parameter, so that the bus bandwidth occupied by the image processing process is adjusted, and the adjustment of the bandwidth occupied by the image processing process is achieved. According to the method provided by the application, the bandwidth occupation amount of the equipment in the image processing process can be adjusted. When the bus bandwidth occupation in the hardware equipment is low, the bandwidth occupation in the image processing process can be increased; when the bus bandwidth occupation in the hardware equipment is high, the bandwidth occupation in the image processing process can be reduced. The method and the device adjust the bus bandwidth occupied in the image processing process in real time according to the needs, thereby balancing the bus bandwidth resources in the hardware equipment and ensuring the stable operation of the hardware equipment. The method does not need to replace devices in the equipment, and reduces the operation complexity and cost.
For further description of the present application, the present embodiment applies the method disclosed in the present application to an embedded device, which may be a doorbell as shown in fig. 3. The doorbell is provided with a frame buffer memory, a bus, a memory, a CPU, an image processing module and other devices.
The Frame buffer memory (Frame buffer) is called Frame buffer or video memory for short. The Linux abstracts the Framebuffer device for the user mode process to realize direct screen writing. The Frame buffer mechanism imitates the function of the display card, abstracts the hardware structure of the display card, and can directly operate the display memory through reading and writing of the Frame buffer.
In fig. 3, when a user uses a doorbell to make a call, the display interface displays a portrait, which needs to be clearly displayed, and the contents such as "return", "time", etc. do not need to pay much attention. Therefore, the picture layer (the first picture layer) to which the portrait belongs can be clearly processed, and the data volume occupied by one pixel point is increased a little; the picture layer (second picture layer) to which the contents such as "return", "time" and the like belong can be normally processed, and the data volume occupied by one pixel point is adjusted to be smaller or not adjusted.
Of course, in practical application, the data volume occupied by one pixel point can be set as a universal value, and when the data volume is required, the universal value is increased or decreased.

Specifically, after the adjustment is completed, the image processing process of the first picture layer can be referred to in fig. 4, and the image processing process of the second picture layer can be referred to in fig. 5.

The "format conversion" after the Frame buffer may be: RGB565, ARGB1555 or BGRA5551 and the like are converted into YUV422, YUV420 or RGB565 and the like, and if the current equipment can be compatible with RGB565, ARGB1555 or BGRA5551 and the like, the conversion is not needed.
In fig. 5, "format conversion" before Frame buffer is: and converting common image formats such as JPEG and BMP or customized image formats into CLUT _8BPP, CLUT _4BPP, CLUT _2BPP or CLUT _1 BPP. There is generally no more format conversion after the Frame buffer. The 8-bit (CLUT _8BPP) mode is a table lookup method, and the image processing module can find the color value corresponding to each pixel ID.
It should be noted that other implementation steps in this embodiment are the same as or similar to those in the above embodiment, and therefore, the description of this embodiment is omitted here.
Therefore, the bus bandwidth is adjusted according to the method provided by the application, and the display frame can be displayed on the equipment display interface based on the user requirement, so that the equipment performance and the user experience are improved.
