Countercurrent 1982

Chapter 1863 Miniature Car Design
It is precisely because of this that Duan Yun’s Spark Studio has been working hard to develop MP3 audio compression software. The current compression ratio has reached 8:1, which is only one step away from the mature m P10 technology of 1:3 in the future.

以10:1的比例将700MB压缩为70MB，将一首大约5分钟的歌曲，压缩到4~5MB，这就已经具备了研发MP3的硬件标准。

Taking the new-generation flash memory chip with a storage capacity of 32MB as an example, only two chips are needed to produce an MP64 with a capacity of 3MB. However, according to Duan Yun, there is still no basis for making an MP3 player.

First of all, the cost of the newly produced 32MB chip is relatively high. The main reason is that this chip has just been developed, and the yield rate is not high. According to Liang Mengsong’s report, the yield rate of this 32MB chip is less than 50%. %, if you want to reach more than 85%, it will take at least half a year to a year. The low yield rate means that the cost will be high and lack cost performance.

In addition, two chips are needed to make an MP3 player. If there are more chips, on the one hand, data transmission will be delayed, resulting in unsmooth playback of songs; on the other hand, the volume will be enlarged accordingly, which cannot achieve convenient effects. , and the price of more than two chips is indeed very expensive. According to preliminary estimates, it will cost at least three to four thousand yuan. This is only the cost price, and the market price will be higher.

Relatively speaking, the price of hard disk storage is much lower. A 1GB hard disk launched by Western Digital at the end of last year costs $210, and the cost of 1MB storage capacity is only about $0.2, but 1 MB of flash memory chip is It is dozens of times that of mechanical hard disks. In this respect, solid-state hard disks with flash memory chips as storage components cannot be compared with mechanical hard disks in terms of cost performance. Until 2010, with the technological breakthrough of flash memory chips, solid-state Hard disks have only begun to become popular all over the world and have entered computers in thousands of households. Before that, solid-state drives were a luxury electronic product.

Therefore, if Duan Yun wants to make a truly cost-effective and market-competitive MP3 player, he still needs to wait for a while. After the self-produced scattered memory chip technology is mature and the cost is reduced, he will have the technology to produce MP3 on a large scale. Base.

But in any case, this is a breakthrough in flash memory chips, and it is a major breakthrough of historic significance for both Tianyin Group and China's microelectronics industry. Duan Yun can rely on this chip to develop a series of leading performance chips. high-tech products.

Duan Yun, who was informed of the situation at this time, did not return to Shenzhen immediately. He planned to stay in Shenyang for half a month this time, and it is very likely that he will run back and forth between Shenzhen and Shenyang in the future. The microelectronics and automobile industries are his future. The two core businesses of development.

"...My idea is this. Taking our current consumption situation in the Chinese auto market as an example, the high-end cars worth RMB 30 million are beyond the reach of most ordinary consumers. But if the price of new cars can be controlled to 4-6 If it is around [-] yuan, there will definitely be a very good sales volume.” In the conference room of the Shenyang Automobile R&D Center, Duan Yun called all the auto experts from the former Soviet Union and Chinese personnel for a meeting to discuss, only to hear him continue: “We The prototype of the new car can refer to the Suzuki Alto model imported from Japan. Although this mini car is far inferior to high-end cars like Volvo in terms of performance, it is very cost-effective and affordable for quite a few ordinary people. In addition to cost, the new car must be fuel-efficient, durable, and easy to maintain, so that it can become a best-selling national model..."

"Manager Duan, I think I should understand your thoughts." Zhukovsky, who was sitting next to Zhao Yun, was the first to say after listening to Duan Yun's story: "Actually, our country has produced several A similar miniature car, such as the Zaporozhets produced in Ukraine, is very popular in our country. In addition, there is also the Lada ZAZ565, which is also very good. Many parts of this car are produced by our Gorky Automobile Factory... "

Speaking of miniature cars, Zhukovsky, who is a different engineer of the Gorky Automobile Factory, is absolutely familiar with it. Among them, he has personally participated in the design of two miniature cars, and in the following years, he has also participated in related projects. Model upgrades and improvements.

Moreover, Soviet mini cars are not only very popular in China, even in the 80s, Soviet-made Lada cars were exported to the US market in batches.

This Lada car was advertised in the United States as "Add a Lada to your life".

This model is Zaz565 Lada miniature car, from the famous Soviet Volga Automobile Factory.

The Volga Automobile Factory is located in the city of Togliatti named after the famous Italian communist Palmiro Togliatti.

The Volga Automobile Factory was established in 1966. At the beginning of its establishment, Lada decided to use Fiat's family model as a replica version. The Soviets hoped to produce a simple and practical small car to meet demand.

After comparison, the Fiat 124 car was finally selected. In April 1970, using the Fiat 4 car as a template, the Soviets manufactured their first new car Lada. By 124, the total number of Lada cars manufactured had exceeded 1984 million, becoming the Soviet Union's first car. national car.

In terms of size, this Lada car is almost the same as the Japanese Suzuki Alto. Although the international price is cheaper than the Alto, its performance technology is relatively backward, and its fuel consumption is also slightly higher.

However, the times are advancing, and top automotive engineers like Zhukovsky are also making continuous progress. If there is enough capital investment, he himself can indeed lead the team to develop a car with similar performance and cost price to Alto.

"Comrade Zhukovsky, since you have experience in developing related miniature cars before, I will entrust you with the task this time. I need you to come up with the design plan as soon as possible, and you can ask me how much budget you need. Apply." Duan Yun thought for a while, and then said to Zhukovsky: "In addition to the various performance indicators of the car, we must also pay attention to the appearance of the car. Next, I plan to hire internationally renowned experts with high salaries. Car designer, help our car design several sets of appearance plans, all in all, make our car look practical and advanced, and I need to see the first one you designed and manufactured at the beginning of next year A prototype car!"
