In the prior art, multimedia link verification based on simulation of a cadence palladium z1, namely a hardware simulation system (hereinafter abbreviated as PZ 1), namely a simulation platform, is generally completed by a VSB system provided by cadence corporation. As shown in fig. 1, when using the VSB system, a verilog block, i.e., a hardware description language block, must be instantiated in an emulator, i.e., a simulator, and this verilog block is referred to as VSB _ CSI _ TOP. VSB _ CSI _ TOP and DUT _ CSI (Design Under Test Camera Serial Interface, namely a Serial Camera Interface to be tested) are connected through a PPI Interface of MIPI DPHY protocol.

However, output data processed by the DUT CSI is generally in a user-defined format, and accurate comparison and visual observation of image data input and output cannot be performed through the prior art.

Referring to fig. 5, fig. 5 is another schematic flow chart of the image comparison display method according to the embodiment of the present invention, and as shown in fig. 5, the image comparison display method according to the embodiment of the present invention includes steps S501 to S504.
S501, the processing unit acquires the input image data and the output image data and performs initialization configuration according to configuration information;
py, the script interface provided by view includes:
1) Input _ file: the input image source file needs to be assigned to a specific image. The default value is Input _ none.
2) Output _ file: data read from the memory by the memory-dump. Since the read data needs to be spliced into multiple files, the read data needs to be assigned to a folder. The script reads the files in the folder for automatic splicing. The default value is Output _ none.
3) vact: the number of images per line of the input image. The default value is 1280.
4) hact: default value is 800.
5) mode: an image format is input. The default is rgb888 for raw format, the script can only compare, not display.

s504, the processing unit obtains corresponding effective pixel components according to the input sampled image and the output sampled image, and calls a display function of the script to display the input image data and the output image data corresponding to the first effective pixel component and the second effective pixel component in the view file.
Specifically, as shown in fig. 6, a data processing flow diagram of a view file view is illustrated in an RGB888 image format with a resolution 1280 × 720 according to an embodiment of the present invention.
1) Hex, input configuration information, input image data Input _ img, hex, output image data Output _ img.
The configuration information is as follows:
-Input_file Input_img.hex
-output_file output_img
-vact 1280
-hact 720
-mode rgb888
-disonly 1
-compare 1。
since vact defaults to 1280 and mode defaults to rgb888, these two parameters may not be configured.
2) Hex, after searching the image start position, the Input image data Input _ img, start sampling the Input data, extract the R/G/B components of the effective pixels and splice into { R [7:0], G [7:0], B [7:0],8 'b00', and the Input sample image Input _ sample. The data sample storage format changes as shown in fig. 7.
3) For the Output image data Output _ img _ xxx, since dump is started from the address of the first pixel in memory-dump, sampling processing of the Output data is directly performed, effective pixels are extracted, and the effective pixels are also spliced into { R [7:0], G [7:0], B [7:0],8 'by 00', and the Output sample image Output _ sample. The data sampling storage format thereof is changed as shown in fig. 8, and image data is output.
4) When the image is displayed, the files of the Input sampled image Input _ sample.dat and the Output sampled image Output _ sample.dat are respectively processed, the components of R, G and B are firstly split, and a python script language with a display function is called in view.
The display flow codes are as follows:
for y in range(0，thact)：
for i in range(0，tvact)：
data0 = rgb_in0.readline()
r_l.append(int(data0[0：2]，16))
g_l.append(int(data0[2：4]，16))
b_l.append(int(data0[4：6]，16))
im =Image.new(“RGB”，thact，tvact)，“white”)
for i in range(0，thact)：
for j in range(0，tvact)：
im.putpixel((j，i)，(r_l[i*tvact+j]，(g_l[i*tvact+j]，(b_l[i*tvact+j]))
im.show()
referring to fig. 9, fig. 9 is a flowchart illustrating an image comparison display method according to an embodiment of the present invention, and as shown in fig. 9, the image comparison display method according to the embodiment of the present invention includes steps S801 to S803.
S801, the processing unit compares a first effective pixel component in the input sampled image with a second effective pixel component in the output sampled image one by one according to pixel points with the same pixel coordinate to judge whether the first effective pixel component and the second effective pixel component are consistent;
s802, if the inconsistency exists, the processing unit prints the pixel values and the pixel coordinates of the inconsistent pixel points into a log file;
if the input image data and the output image data are completely consistent with each other, the processing unit prints a character string indicating that the input image data and the output image data are identical to each other in a log file.
Specifically, 5) when comparing data, comparing effective pixels of the input sampled image with effective pixels of the Output sampled image one by one, and judging whether the pixel comparison is inconsistent. If there are inconsistent pixels, the current pixel value and coordinates are printed into log. If all the alignments agree, the key for the all pixel match pass is printed. Py, when the same data format but different data arrangement needs to be added, only the data sampling part of the step 2) or the step 3) can be added, and the data display and comparison parts in the steps 4) and 5) are kept unchanged. When a different format (such as yuv) needs to be added, a different format display process can be added in the step 4), and the data comparison in the step 5 is kept unchanged. The expandability of the whole script processing is improved. Py is a python script file for processing data and image display.
The simulation of the emulation platform based on pz1 is combined with the actual use, the defects of the existing scheme are summarized, and the following beneficial effects are obtained:
1. the problem of the image can be visually perceived from the naked eye by displaying the input/output image using the python script.
2. And each pixel point of input and output can be accurately compared, and specific error pixel point information is accurately printed.
3. If there are many kinds of input and output format arrangement, the invention has stronger expandability.
