Probably because Mr. Jiang was very satisfied with the rise of Chongguang, his inspection today lasted until noon that day.

After sitting down on the sofa in the living room of Chongguang Company, the elder showed his extensive knowledge, drinking tea and laughing, and sprinkled all kinds of fields, from astronomy and geography to the human world, and asked all the topics about Chongguang, from the salary structure of employees to various technical details. Hu Yiting originally planned to hold a banquet at noon to entertain Mr. Jiang, but he failed to keep it and was rejected by him.

Mr. Jiang held Hu Yiting's hand before parting, and explained to him earnestly: "You are the best private enterprise in China at present, and you are also the private enterprise with the highest salary and the best welfare treatment among the private enterprises I have seen, and you have truly mastered the core technology.

You and Chongguang company is a valuable force for the development of national science and technology, I hope that you Hu Yiting will continue to put the development of science and technology in the first place, for the future to be full of confidence, but also to have firm perseverance, to learn the advantages of world-class enterprises, to take every step in a down-to-earth manner, to strive to make greater contributions to the great rejuvenation of the Chinese nation. ”

Hu Yiting listened attentively, and finally nodded: "Secretary Jiang, I remember your words, you can rest assured." ”

Mr. Jiang only smiled and left a sentence before getting into the car at the end: "I'll come back next year." ”

Hu Yiting nodded happily, but he didn't speak, he felt some pressure on his shoulders, but he also felt very moved and full of energy.

Hu Yiting and all the employees on duty of Chongguang Company came to the door to see him off, and after shaking hands with Secretary Jiang, they waved goodbye to Secretary Jiang's motorcade.

After Mr. Jiang's motorcade disappeared at the end of the road, the personnel in charge of security of the Central Guard Regiment quietly walked away at some point.

Hu Yiting was in a very good mood and announced that the company would have dinner at a nearby restaurant called Xiangxiu Restaurant at noon today, so the colleagues had a drink and fun during the banquet, and everyone's morale was also extremely high.

It was nearly two o'clock in the afternoon when I returned to the office after dinner.

Hu Yiting did not rest, and when he returned to the office, he continued to concentrate on the development of DVD decoding chips.

According to the technical information delivered by ARM's senior management during their visit to China, although ARM has not yet completed the research and development of embedding the Strong-ARM instruction set into the V4 core, the basic idea is already there, that is, to continue to improve the principle of low power consumption and strive to maximize performance, rather than ignoring power consumption in order to improve performance.

Hu Yiting already knows the V4 architecture well, and after getting the STRONG-ARM instruction set and IP design provided by RIC, Hu Yiting's drawing progress is rapid, and he has copied the V4 core by himself, and is embedding it into the DVD decoding chip.

Of course, Hu Yiting's way of drawing is not to do it alone, but to paint only the unique key parts of it.

You must know that in large-scale integrated circuit chips, the number of transistors ranges from tens of thousands to hundreds of thousands or millions, and according to the magic spell of Moore's law, it will gradually reach billions in the future. In the layman's opinion, if you draw them one by one, then even a team of hundreds of people will have to work tirelessly until the end of the earth.

In fact, in the chip, the functions of many transistors are repetitive, as if a field is divided into neat patches of rice fields, and each seedling is the same, as long as the length and width of the rice field and the number of seedlings are marked.

There are also some whole fields, which are already designed, either IP core patent design, or conventional, and there is no need to draw them at all, as long as they are marked in the box, or they are directly covered by chip design software.

The main place that IC engineers need to focus on is some fields designed to implement new functions, such as in order to get sorghum, and in this chip field, another sorghum field needs to be added. In order to achieve the performance of this function, then how much field area is planned for as much sorghum production as it is needed, how to go through the field canals in order to connect with the adjacent rice fields, and how to arrange the underground pipes if the automatic irrigation system is to achieve unified sprinkler irrigation......

In short, IC engineers are more like architectural designers, rather than construction workers who slowly build houses brick by brick, and it is not what some people imagine that IC engineers are coolies.

This job requires a lot more time to think than it takes to actually draw it. This industry is a knowledge-intensive industry, not a labor-intensive industry.

Except for outliers like Hu Yiting, generally speaking, more than 90% of the time of IC design engineers is spent thinking about how to solve problems, and less than 10% of the time is spent on drawing the final finished product.

When it comes to hands-on drawing, the chip design data has been piled up on a thick table in the office, and several notebooks full of design ideas have been accumulated, and finally the work of drawing the product in the design software can be said to be the simplest work and the shortest time. This is the same thing as solving a math problem in an exam, where the person who does the problem has to think for ten minutes and then calculate it on the manuscript paper for a few minutes before putting it down, while the person copying the homework only needs ten seconds to complete it.

The DVD chip designed by Hu Yiting is still copied from the poor ESS company, after Hu Yiting copied the ES3210 VCD decoding chip, in order to achieve the unity of the design idea, Hu Yiting simply reproduced the ES3308 DVD decoding chip.

After working hard until February 5, ESS3308 was finally completely copied by Hu Yiting, so he handed it over to Wu Shihuan, the leader of the multimedia technology development team on duty during the Spring Festival.

Hu Yiting said to Wu Shihuan: "The thing is ready, I already have it on the server, you collectively study and study, do some realistic tests, if there is no problem, you will take the multimedia technology team to sort out the patent overnight, and show it to me after the patent is finished." This matter should be done in a hurry and strive to be completed before the Spring Festival.

Then you can submit it to the patent legal department to submit a patent application, and then ask Sister Wang to send someone to send the chip to Hong Kong Feilong, so that they can quickly tape out, and after success, first invest 300,000 pieces to test the water, sell and sell, and strive to spread the market as soon as possible. ”

For Hu Yiting's genius, Wu Shihuan has become accustomed to nature, and said with a smile: "Hu Yiting, you are too strong, you have completed the development of VCD decoding chips so quickly! This time, our company has another cash cow this year." ”

Hu Yiting smiled: "This thing is similar to the VCD decoding chip, but the algorithm and programming are a little more complicated. ”

Wu Shihuan is now the leader of the multimedia technology development team, and he has already understood the VCD decoding chip developed by Hu Yiting before, and is now leading his engineers with great ambition to follow Hu Yiting to learn the decoding algorithm of MPEG-2 format, that is, DVD format.

"Hu Yiting, according to your instructions, our team has almost finished designing the Dolby AC-3 digital audio solution module, do you think it is going to be embedded in this DVD decoder chip immediately?"

There is a reason why Wu Shihuan asked this.

Originally, Hu Yiting wanted to copy ESS's ES3309, a DVD decoding chip with Dolby audio output, but not long after he started, he felt that it was more appropriate to copy ESS's first DVD decoding chip ES3308.

Hu Yiting thinks,ES3308It's a single-chip decoder,The sound quality output through the TV's built-in speakers is mediocre。 The ES3309 chip integrates the Dolby AC-3 digital audio decoding solution, which can provide users with up to 5.1 channels of surround sound output through the audio output port behind the DVD player, so that DVD users can use the speaker to DIY a small home theater at home.

But the problem is that Dolby has to collect patent fees! Dolby AC-3 standard has just been born in 94 years, and this year is the hottest time, as the hottest top audio decoding output solution at this time, the patent fee for each chip integrating Dolby AC-3 audio solution is up to $10, and in the end it is not to be spread on the user's head!

For users in this year, cost performance is still very important.

So Hu Yiting decided to reproduce the ES3308 first, and then asked the U.S. branch to contact Dolby to get the patent authorization.

Dolby lives on licensing, and is naturally open to companies willing to integrate their own digital audio solutions.

Xiaoma quickly sent a reply, telling Hu Yiting that Dolby's license fee was indeed a $10 patent fee per chip, so that DVD players using the chip could be allowed to use the Dolby AC-3 technical trademark on their packaging and chassis, and the unique logos of the two speakers in Dolby's eye-catching box were pasted, so that users could see at a glance that the sound quality of the device was guaranteed by Dolby technology.

Hu Yiting asked Xiaoma to immediately sign a contract with Dolby and send it back to the company for the record, and then asked Wu Shihuan to lead his multimedia technology team to develop an independent Dolby audio decoding module, intending to embed the module into the design of 3308 after the design of 3308 is completed, and make a ESS3309.

In this way, a clear market division between low-end and high-end can be achieved in DVD chips, so that DVD manufacturers have the right to choose freely.

Anyway, if someone is willing to pay for Dolby sound, then they will buy a machine with a high-end chip.

But after all, most people don't buy DVDs to set up a 5.1 speaker home theater in the living room, ordinary people just want to watch DVDs on TV, Hu Yiting doesn't want ordinary consumers to spend money in vain.

So Wu Shihuan asked Hu Yiting before if he could embed it.

Hu Yiting thought for a while: "Sort out the patents first, and then you can embed them." I won't interfere this time, it's up to you to do it, and if you make something with Dolby, it's a new product, which is considered a high-end product, and it can be sold to rich people. ”

Wu Shihuan was a little excited, this is the first time he has been responsible for the independent development of a product in the company, although this is based on the products that Hu Yiting has designed, but it is also a great development experience.

"Okay, then I'll do it!" Wu Shihuan said excitedly, and ran out of the office in a hurry. ”

After walking for a while, Wu Shihuan ran back again: "Hu Yiting, have you thought about the name of this chip? ”

Hu Yiting said casually: "It's called CMP2J1, and after you design a new product that integrates the Dolby AC-3 solution, it's called CMP2J2." ”

"It's the same as before, okay, I see. ”
