If possible, she will also add a high-performance graphics coprocessor (GPU) and soundbar (audio processor) to further improve the multimedia performance of the Dolphin computer.

However, she did not plan to buy these two chips, but designed them herself.

Because neither of these two chips is the brain of a computer, it is just a professional chip, its standards do not have a unified format, and it only controls a single device such as a display and a speaker.

In other words, there are no standards yet, so she can do another set of standards herself.

No matter how many central processors like CPU, there is already a set of standards that everyone has made. Only large companies like Intel have the appeal. Dolphin Technology is difficult to shake its position, and it is impossible to obtain authorization like Amd and can borrow its standards.

The instruction set of computer chips is actually the standard. Peripheral components and components, as well as a large number of application software, must follow its instruction set to design professional interfaces or driver software, otherwise you will not want to sell it. This is the terrifying soft power of an industry leader like Intel.

In terms of desktop computers, you can only follow its standards, and Liu Meijuan is also powerless to change.

Of course, there is no chance to change at all. Just like Apple, it is another set of closed standards.

The premise is that you must have the support of a full upstream and downstream industrial chain and a large number of application software. Apple has this influence. The new Dolphin Technology obviously does not have this strength yet and must survive under the rules of Intel.

In fact, whether it is a graphics processor or an audio processing chip, it is an application of DSP digital processors, and it is nothing more than internal integration of various registers and various dedicated computing cores.

This is not technically difficult for Liu Meijuan. What is difficult is the later simulation and adjustment, which needs to be improved through a large amount of experiments and data collection.

Whether the effect is good or not is often due to these later water grinding skills.

Liu Meijuan is learning from HiSilicon Technology in later generations. She only does design for the time being, and then finds professional chip foundry manufacturers to cut and manufacture.

Regardless of the difficulty of the design, the expense of optical flow chips is a lot of money. The more advanced the chip, the more money it costs due to the process technology.

Because the more advanced the chip, the more complex it is, the cost of making the mask is so high that it can be tens of millions of yuan.

Moreover, due to the later adjustment and running-in, it can be successful with more than one drill, and it may take as many as a dozen times, so the money will be lost.

Dolphin technology today can't bear it at all.

Moreover, all foreign-related economic transactions require valuable foreign exchange, which is controlled by the state. Only when enterprises earn foreign exchange can they retain a little foreign exchange.

That is, how much US dollars you earn, the country will exchange it for you in RMB, and you only have a small part of the foreign exchange retention and use rights.

The so-called foreign exchange retention means that money is stored in the vault of the State Administration of Foreign Exchange. When you want to use it, you will report to the State Administration of Foreign Exchange and apply. In fact, you don’t have a penny of foreign exchange in your hands.

No wonder, in the 1990s, China had only tens of billions of dollars in foreign exchange, but there were many advanced foreign equipment that needed to be purchased. It can be said that such a little foreign exchange is just a drop in the bucket. How can the country not strictly control it?

After thinking about this, Liu Meijuan discovered that she was still a poor man and could not do many things.

No matter how correct these grand blueprints are, the most important thing at the moment is to make money, especially to earn money from exports and foreign exchange. Otherwise, her grand ideal is a fantasy.

Liu Meijuan calculated with her fingers that the only products that the company can export foreign exchange earnings are the x-architecture keyboards, and the ergonomic office chairs that I don’t know if anyone pays for. It can only be considered half a product because it has a lot of uncertainty.

This semi-product earns very limited foreign exchange. I don’t know how long it will take to save enough foreign exchange. If it takes too long, the daylily may be cold.

This certainly doesn't work, one or two competitive products must be developed.

This time, we can no longer create high-end products, we must signify the existing conditions.

Liu Meijuan recalled carefully that it has not appeared yet, but the technology is already available and will be popular in future generations.

VCD already exists, pass! The subsequent DVD technology is an extension of CD and VCD patent technology. It can be developed, but cannot make products to make profits, because Dolphin Technology has not obtained the authorization of these original patent technology holders, which will constitute infringement.

DVD is obviously not a good product that can make profits quickly, and its technology is very difficult. It involves high technologies such as dedicated audio and video decoding chips, laser heads and compression algorithms, and it is not something that can be developed in the short term.

The next step seems to be the era of digital mobile, that is, the era of feature phones. That technology is even more difficult. It is a complete set of system technologies, including mobile base stations, digital signal transmission standards, network servers and mobile phones. Only communication giants like Nokia, Ericsson, Sony and Motorola have the ability to develop.

Liu Meijuan thought of mp3. The inventor of the world's first mp3 file player was invented by Mr. Mooon from Bangzi Country. Moon is the Korean pronunciation of "Wen" in Bangzi Country.

In fact, mp3 is just an audio lossy compression format mpeg-1, and mpeg-2 was launched this year.

It was invented and standardized in 1991 by a team of engineers from the research organization fraunhofer-gesellschaft in Ellangen, Germany.

What is a lossy compression format? It is that it cleverly increases the compression ratio and even ignores signals to reduce the compression ratio for low-frequency sounds, and tries not to lose the original sound. The compression ratio is 1:10 to 1:12, which greatly reduces the valuable storage and is suitable for the storage and use of mobile devices.

So it was quickly promoted, such as CD and VCD, as well as some user-side software, all used this technology.

The mp3 we call is actually called an mp3 file player. It goes the other way, decompressing the compressed files on the Internet with a dsp digital signal processor, converting the digital information into waveform information through a digital-to-analog converter, and then amplifying the signal by the amplifier and sending it to the audio port. Finally, we can hear beautiful music through the headphones connected to the audio port.

There are also troubles in developing mp3s. You must obtain authorization from the mpeg-2 organization and pay a patent fee to him.

Also, in the years 1995, memory technology almost stagnated, there was no large-capacity ram memory, (flash memory), and no tiny hard disks.

In other words, I can’t save a few songs and do not meet the promotion conditions.

This is a problem that Dolphin Technology cannot solve for the time being, so Liu Meijuan can only give up this delicious cake for the time being.

Then there is the era of mobile Internet. Some digital products are more difficult to technically and generally require the support of mobile Internet. Dolphin Technology is even more incapable of today.

It seems that we can only make some ordinary smart home appliances.

It is said to be smart, but it is not at all related to intelligence. It is just that an embedded industrial control chip and some peripheral circuits can be used for a variety of electrical products, such as variable frequency air conditioners, variable frequency refrigerators, fully automatic washing machines, etc.

However, the above products are technically difficult and have great investment. Dolphin Technology has no foundation and is not suitable for entry.

Liu Meijuan thought of making small home appliances or children's toys. Those investments are very little and the technical difficulty is very small, making them very suitable for start-ups like Dolphin Technology.

However, embedded systems are always software. Dolphin Technology has no software engineer now. Liu Meijuan immediately stood up and wanted to discuss with Wang Yong about the issue of recruiting several software and hardware engineers.
