With the increasing market demand of video display and the rapid development of high-definition video technology, 1080P resolution cannot meet the market demand, so 4K and 8K videos come along, but the pixel clock frequency processed by the video processing device is increased greatly. In order to keep the bandwidth of the resolution unchanged, for the processing of 4K and 8K videos, a method (4PPC) of processing 4 pixels by one clock is mostly adopted at present, and further, the clock frequency is reduced.

[ first embodiment ] A method for manufacturing a semiconductor device
As shown in fig. 1, a first embodiment of the present invention provides a layer moving method. Specifically, the layer moving method provided in the embodiment of the present invention includes, for example, the steps of:
s11: receiving layer moving information, wherein the layer moving information comprises a layer moving direction and the number of layer moving pixels;

Therefore, the number of the residual moving pixels is obtained according to the number of the moving pixels of the image layer, and then the pixel position compensation is carried out on the residual moving pixels, so that the image layer with the distance of the number of the non-integral multiple clock frequency pixels can be moved, the problems of blockage, discontinuity and the like caused by the movement of the image layer with the distance of the number of the non-integral multiple clock frequency pixels in the prior art are solved, and the display effect when the image layer moves is improved.

Further, as shown in fig. 4, in another embodiment of the present invention, the performing pixel padding on the layer to be moved according to the layer moving direction, the number of pixels with the clock frequency, and the number of remaining moving pixels in step S191 includes:

In order to facilitate understanding of the present invention, each step of the layer moving method of the present embodiment will be described in detail below with reference to fig. 5 to 6C.
The layer moving method provided by the embodiment of the invention is suitable for a video processing device to process the situation that the layer moving is processed in an nPPC mode. The video processing apparatus herein is, for example, a video processing apparatus. For example, as shown in fig. 5, a video processing device is connected to a display screen. The display screen may be, for example, an LED display screen, or may also be other display screens such as an LCD, and the invention is not limited thereto. The video processing device mainly comprises an embedded processor and a programmable logic device connected with the embedded processor. The Programmable logic device is, for example, an FPGA (Field-Programmable Gate Array), and is configured to receive a video source input, process a layer of the input video source, and output processed video data to a display screen for display. The embedded processor is, for example, a processor based on an ARM core, and is mainly used for loading an FPGA program, transmitting and receiving a display control instruction, and the like. The following describes in detail the layer moving method provided in the embodiment of the present invention, by taking an example that the number of clock frequency pixels is 4PPC (that is, 4 pixels of one clock processing layer), and the distance of moving the layer, or the pixels are non-4 integral multiples of pixels.
Firstly, an embedded processor receives a layer moving instruction generated by user operation, analyzes the layer moving instruction to obtain layer moving information, and then sends the layer moving information to a programmable logic device (FPGA) connected with the layer moving information. And receiving the layer moving information by the FPGA. The layer moving instruction may be generated by a user operating a key of the video processing device, or may be generated by a user operating corresponding upper computer software on an upper computer connected to the video processing device, for example, which is not limited in the present invention. In addition, the layer movement information includes a layer movement direction and a layer movement pixel number (or referred to as a layer movement distance). The layer moving direction may be, for example, a left-right direction, an up-down direction, or the like of the layer. The present embodiment will be described by taking the left-right direction of the layer movement as an example.
And then, the FPGA acquires the layer to be moved. The layer to be moved obtained here may be understood as obtaining pixel data of the layer to be moved, that is, pixel data and pixel position of each pixel on the layer to be moved. The pixel data of a pixel typically includes ARGB data, i.e., a transparency coefficient (a) of the pixel and RGB color gray values of the pixel.
And then, the FPGA determines the number of the mobile clocks and the number of the residual mobile pixels of the layer to be moved according to the number of the clock frequency pixels and the number of the layer mobile pixels. Specifically, the FPGA divides the number of the layer moving pixels and the number of the clock frequency pixels; taking the quotient obtained by division operation as the number of the mobile clocks; and taking the remainder obtained by the division operation as the number of the residual moving pixels. For example, the number of layer shift pixels of the to-be-shifted layer (or) is 13 pixels, and the number of clock frequency pixels is 4, so that the number of layer shift pixels and the number of clock frequency pixels are divided, a quotient obtained by dividing the number of layer shift pixels by the number of clock frequency pixels is 3 as the number of shift clocks, and a remainder obtained by dividing the number of layer shift pixels by the number of clock frequency pixels is 1 as the number of remaining shift pixels.
Then, the FPGA determines whether the number of the mobile clocks is zero. And responding to the situation that the number of the mobile clocks is not zero, and the FPGA moves the layer to be moved according to the layer moving direction, the number of the mobile clocks and the number of clock frequency pixels (4 PPC). For the foregoing example, the number of the mobile clocks is 3 and is not zero, and the FPGA moves the layer to be moved by a distance of 3 × 4 and 12 pixels in total along the layer moving direction. Of course, if the number of shift clocks is zero, i.e. the number of layer shift pixels with shifted layers is smaller than the number of clock frequency pixels (4PPC), i.e. the number of pixels processed by less than one clock, then this step need not be performed.
Secondly, the FPGA judges whether the number of the residual moving pixels is zero or not. And responding to the condition that the number of the residual moving pixels is not zero, and the FPGA carries out bit complementing movement on the layer to be moved according to the layer moving direction and the number of the residual moving pixels. Specifically, the FPGA performs pixel bit-filling on the layer to be moved according to the layer moving direction, the clock frequency pixel number, and the remaining moving pixel number, and then moves the layer to be moved after bit-filling along the layer moving direction, where the moving pixel number is equal to the clock frequency pixel number, or the moving distance is equal to the distance of the clock frequency pixel number. Furthermore, the pixel bit-filling, by the FPGA, the to-be-moved layer according to the layer moving direction, the clock frequency pixel number, and the remaining moving pixel number includes: a first pixel block with a first number of complementary pixels at the front part of the moving picture layer along the moving direction of the picture layer and setting the pixels of the first pixel block as transparent pixels, wherein the first number is equal to the difference value between the number of the clock frequency pixels and the number of the residual moving pixels; and a second pixel block with a second number of complementary pixels at the rear part of the moving picture layer along the moving direction of the picture layer, and setting the pixels of the second pixel block as transparent pixels, wherein the second number is equal to the number of the residual moving pixels. In order to more conveniently understand the process of the present step, the embodiments of the present invention are still illustrated by the foregoing examples. As described above, the number of remaining moving pixels is 1, which is less than the number of pixels processed by one clock, and therefore, if the part of pixel data is to be moved without data loss, tearing, or other problems, the part of pixel data corresponding to the number of remaining moving pixels needs to be subjected to pixel padding. As shown in fig. 6A, it is assumed that a row of pixel data (dat) of a layer to be moved is 8 pixels, and the number of clock frequency pixels is 4PPC, so that a row of pixel data of the layer to be moved is distributed in 2 clocks (clk), two effective image data indicating signals (de) of the pixel data of two 4 PPCs are assumed that the sequence of 8 pixels is 01234567 in turn, and the sequence is as shown in fig. 6A, where it is worth mentioning that when packing the pixel data into the row of pixel data (dat) in the 4PPC mode, the pixel data of 4 pixels are packed in each clock range, that is, each dat is packed with 4 pixel data respectively; in addition, the way of storing the pixel data into the row pixel data is: the pixel data with the larger storage address is stored on the left, the pixel data with the smaller storage address is stored on the right, and among the 8 pixels, the storage address of the pixel 7 is the largest and the storage address of 0 is the smallest, so in fig. 6A, the storage order of the 8 pixels in dat is 3210-. Of course, the packing of the row pixel data (dat) can also be performed in other manners, and the invention is not limited thereto.
Since the number of remaining moving pixels is 1, it is necessary to move the layer to be moved one pixel (or a distance of one pixel) to the left or right. As shown in fig. 6B, when the FPGA moves the layer to be moved by one pixel to the right, the FPGA delays the length of the effective image data indication signal (de) by one clock, i.e. there are three de signals, and then supplements a first number of first complementary pixel blocks in front of the pixel 7, where the first number is equal to the difference between the number of clock frequency pixels and the number of remaining moved pixels, i.e. 4-1-3, i.e. supplements a first complementary pixel block (xxx) of 3 pixels in front of the pixel 7, and sets the transparency coefficient (a) in the pixel data of the 3 pixels of the first complementary pixel block to 1, i.e. the pixel data of the 3 pixels of the first complementary pixel block is transparent; the RGB data can be set arbitrarily or by default to RGB (0,0,0), i.e. 3 pixels of the first complement pixel block are transparent pixels; subsequently, a second number of second complement pixel blocks are supplemented behind the pixel 0, wherein the second number is equal to the number of the remaining moving pixels, namely 1 pixel, namely a second complement pixel block (x) of 1 pixel is supplemented behind the pixel 0, and the transparency coefficient (A) in the pixel data of 1 pixel of the second complement pixel block is set to be 1, namely the pixel data of 1 pixel of the second complement pixel block is transparent; the RGB data can be set arbitrarily or by default to RGB (0,0,0), i.e. 1 pixel of the second complement pixel block is a transparent pixel; and finally, the FPGA moves the layer to be moved after bit compensation to the right, the number of the moved pixels is equal to the number of the clock frequency pixels, or the moving distance is equal to the distance of the clock frequency pixels which are a number of pixels. Similarly, when the FPGA moves the layer to be moved by one pixel to the left, the FPGA delays the length of the effective image data indication signal (de) by one clock, that is, there are three de signals, and then supplements a first number of first complementary pixel blocks in front of the pixel 0, where the first number is equal to the difference between the number of clock frequency pixels and the number of remaining moved pixels, that is, 4-1 to 3, that is, supplements a first complementary pixel block (xxx) of 3 pixels in front of the pixel 0, and sets the transparency coefficient (a) in the pixel data of the 3 pixels of the first complementary pixel block to 1, that is, the pixel data of the 3 pixels of the first complementary pixel block is transparent; the RGB data can be set arbitrarily or by default to RGB (0,0,0), i.e. 3 pixels of the first complement pixel block are transparent pixels; then supplementing a second number of second complementary pixel blocks behind the pixels 7, wherein the second number is equal to the number of the remaining moving pixels, namely 1 pixel, namely supplementing a second complementary pixel block (x) of 1 pixel behind the pixels 7, and setting the transparency coefficient (A) in the pixel data of 1 pixel of the second complementary pixel block to be 1, namely the pixel data of 1 pixel of the second complementary pixel block is transparent; the RGB data can be set arbitrarily or by default to RGB (0,0,0), i.e. 1 pixel of the second complement pixel block is a transparent pixel; and finally, the FPGA moves the layer to be moved after bit compensation to the right, the number of the moved pixels is equal to the number of clock frequency pixels (4PPC), or the moving distance is equal to the distance of the clock frequency pixels (4PPC) pixels. For the remaining number of shifted pixels being 2 or 3, the shifting principle and steps are completely the same, and the number of pixels to be shifted or the number of pixels to be shifted is different, which is not described herein again. In this way, layer shifting of non-integer multiples of the clock frequency pixel count is accomplished. Of course, if the number of remaining shifted pixels is zero, that is, the number of layer shifted pixels with shifted layers is an integer multiple of the number of clock frequency pixels (4PPC), then this step is not required.
In summary, in the embodiments of the present invention, the number of remaining moving pixels is obtained according to the number of layer moving pixels, and then the pixels are integrally moved and bit-complemented according to the remaining moving pixels, so that the movement of the layer with the non-integer-multiple clock frequency pixel number distance can be realized, the problems of stutter, discontinuity, and the like caused by the movement of the layer with the non-integer-multiple clock frequency pixel number distance in the prior art are solved, and the display effect when the layer is moved is improved.
