Shen Danqing pushed open the door of the conference room and walked in, only to see Hong Tao standing on the stage drawing on a makeshift blackboard.

"Wow! you're having a technical seminar!"

Shen Danqing said loudly and heartily.

Shen Danqing's loud voice immediately alarmed the audience, including Hong Tao on the stage. Shen Danqing is a frequent visitor here, and everyone knows him. So they almost unanimously greeted him: "Boss".

More than a hundred people shouted at him in unison, and his voice was very loud, which made Shen Danqing very comfortable. With a smile on his face, he said, "Let's continue the meeting, and I'll be an observer." ”

"Boss, we're talking about the system architecture of the color display control chip. You've come just in time, please check on us. Hong Tao on the stage said to Shen Danqing.

"I don't understand the specific technical details, but I can still give some opinions on the main architecture of this chip. "Shen Danqing is not modest, the purpose of his coming this time is also for the system architecture.

"Boss, please speak, let us all listen to your valuable opinions. Hong Tao knows that the boss doesn't understand technology, but he can often put forward some programmatic opinions and ideas. This is reflected in many important scientific and technological developments, which is why he said this.

Shen Danqing didn't talk nonsense, he walked directly to the rostrum, picked up a piece of chalk and began to say: "If you want to achieve a satisfactory image display effect, a chip is far from enough. So in fact, we also need to have a chip, called a graphics co-processing chip. At this point, he wrote the words "graphics co-processing chip" in chalk. Then he continued: "So you should pay attention to this when designing the color display control chip, and leave the interface." The graphics coprocessing chip is upgradable, which means that it is replaceable. The color display control chip is fixed with the display screen and does not need to be upgraded. Only when the screen display technology is upgraded, it will be upgraded.

There are two directions for the upgrading of display technology in the future, one is to develop to a more delicate degree. With our current technology, there is not much potential for this development, but I can't be completely sure about it right now. After all, how far will the technology of the future go?

The second direction of technological development is: 3D graphics display technology. Other companies use graphics coprocessors to display 3D graphics, which is simply expressed by the use of light and shade colors. to achieve the effect of a 3D image. This method cannot be said to be wrong, the human eye can be deceived. As long as it is achieved so that the human eye can see the three-dimensional shape, it is a good method. But I want to improve the display technology as well. This is done by adding an additional layer of LEDs to the existing LEDs. The LEDs in this layer only show the shadow of the previous graph, so that we can achieve a more satisfactory 3D image display.

Therefore, you should pay attention to this key factor when designing color display control chips.

Since there is a separate graphics co-processing chip responsible for the color effect, we need to design this chip to display a simple black and white image effect or a single primary color effect. We should focus on the two technical points of graphic delicacy and image display response sensitivity.

In addition, the amount of buffer should be increased, and the image signal is transmitted to the central processing chip in the form of digital packets, and then the central processing unit parses these digital packets into a frame of image signals, and then transmits them to the image display control chip. Therefore, the chip must be integrated with the cache, and there must be at least two levels, and as much as possible, the three-level cache must be integrated. The purpose of caching is to store enough graphics signals so that even the occasional frame drop does not affect the coherence of the screen display.

The image is displayed in the form of frames, so we need to set the rules of the frames. Because the image is not always full-screen, there should also be a floating image, which is a small image that is overlaid on top of a full-screen image. This small image can be a half-screen, a very small piece, a transparent graphic, or even a control point. This point is what is called the mouse point on the computer. Therefore, the forms of suspended images are varied. In everyone's mind, we must have this concept, and don't be formed by the inertial thinking of the immutable full-screen TV picture.

Finally, there is another important technology, and that is local image enhancement. It is to make up for an unclear picture by an image algorithm in a certain part. Enables people to see clearer images. This technology is the main task of the central processing unit and graphics coprocessor in the future, but the image display control chip also has to take on part of the control task, so I specifically point it out here.

On this occasion, I will talk about graphics co-processing chips. In fact, this chip is separated from the image display control chip, and it has only a single function, which is to enhance the image display effect. That is, it is responsible for the performance of colors, such as light and dark contrast, color vividness, delicacy of color transitions, and so on. Why do we have to design such a chip alone? It is because this chip should be versatile, it can be used not only on our own display, but also on the motherboard of the computer, and also to enhance the image display effect of the computer. In addition, it should also be able to be used on other people's screens to enhance the image display effect in the same way. Because a screen is very expensive, many people are reluctant to change it, if adding a piece of our graphics co-processing chip can significantly improve the image display performance, they will definitely add it. This is no longer just for new products, but also for customers' old displays. At this point, you should understand why I designed a graphics co-processing chip separately.

All right, that's all I have to say! You go ahead and have a meeting. After Shen Danqing finished speaking, he threw away the chalk, walked off the rostrum, and sat down under the stage for the first time.

The boss went down, and Hong Tao continued to preside over the meeting on the stage. He looked at the boss and found that the boss was sitting down like an ordinary officer, waiting for him to speak, and then began to say: "The boss talked so much just now, and talked about a few important technical points. One of the most important is to strip out the color image effect function and design a separate graphics co-processor.

Then our previous system architecture will be overturned, and then the architecture of the graphic display control chip will be redesigned. So my idea is ......"

Hong Tao began to talk about his understanding according to the ideas provided by Shen Danqing. As he spoke, he was out of control, and he spoke for more than two hours. Later, he found that it was almost time to eat, and the boss was still below, so he made a final conclusion: "Okay! It's time to eat, so that's all for the time being." In the afternoon, we continued our meeting for a detailed discussion. Meeting. ”

After Hong Tao announced the dismissal of the meeting, he walked up to Shen Danqing and invited: "Boss, it's a rare opportunity, let's go have a light meal together!"

"No, I've achieved my purpose here, so there's no need to stay here anymore. I'll go back first, but you must speed up the chip design, you know, there are still several chips waiting for you to design the display screen alone, hurry up! Shen Danqing declined Hong Tao's invitation, and then urged him to speed up the design. After finishing speaking, he left the Institute of Electronics with Secretary Liu.

Shen Danqing's visit to the Institute of Electronics is of great significance. First of all, he stripped out the function responsible for the color display effect and set it up as a separate graphics co-processing chip. Then the function of the remaining graphic display control chip is much simpler, which is more in line with the requirements of low-end displays. For example, the small window display screen on a small household appliance only needs to display simple words and numbers, and at most a fixed dynamic picture. And the color is only red, green, and blue, so only a graphic display control chip with the buffer unit removed and a RoM chip with a solidified control program can be added. This results in significant cost savings.

Secondly, the technologies he talked about later are all very important technologies. The function of floating windows and picture-in-picture is not unusual, and other companies also have this technology.

As mentioned later, the image local enhancement effect technology is his original and will not be available in later generations. In later generations, only the multiplier function could not improve the image clarity. It's just that the image is enlarged. Shen Danqing's technology is to make the image clearer by algorithmizing the original image that is not very clear in a certain part to make the image clearer. This technology later led to a significant increase in the sales of Changsheng Investment Group's display screens, which was well received by users. There are two groups of people who are most interested in this technology, the first group of people are scientific researchers, who need to carefully observe the parts of the image because of the needs of their work. This technology is exactly what they desperately need.

The second group of people is huge. It covers almost the entire population of society. That is the person who likes to watch colored art films, and this technology allows them to see a clear image of a certain part. Because this kind of crowd is too large, the sales of Changsheng Investment Group's display screen are far ahead, leaving its peers far behind.

What you may not know is that it's not just the high pixel size of your display that gives out a sharper image. The clarity of the image is related to the standard of the image at the time of shooting. There are a large number of art films in the past that have low image definition because of the lack of advanced shooting technology, but some people still like to watch them. In the past, when there was no image local enhancement technology, they had to endure it, and now the display screen of Changsheng Investment Group is their gospel.

Shen Danqing's 3D image technology is also his original, and no display screen in later generations has this technology, which is a proper black technology. Shen Danqing is such a person, he can always think of technology that others don't have.
