Super Copy of Great Power Technology

This kind of operation is very common in the field of computer CPUs. Many low-end models of CPUs are obtained by shielding some defective cores. For example, the famous U-Athlon 5000, the first-generation core-developing machine, changes from dual-core to quad-core after the core is enabled, and the performance is doubled. However, whether the core is successful or not depends entirely on the face, because the two shielded cores are likely to be defective. . In the field of mobile phone SOC, there are very few low-end chips made by shielding some cores, because today's mobile phone chips have relatively few cores, two cores are the mainstream, and four cores are rare. Eight-core SOCs like Kyushu No. are unique. .

At this time, in the online live broadcast room, another group of viewers began to speak and discuss,

"The tablet computer priced at 1399 yuan is not much more expensive than those made by those factory manufacturers, but its performance is absolutely crushing. I want to buy one."

"The screen of an 8-inch tablet is a bit too small. It might be good for playing games, but it's not very useful for watching TV shows or watching videos. And Kyushu 425 is just a quad-core chip, so its performance may not be enough."

"The performance of the quad-core chip produced using the 28nm process is not too bad. It can easily handle watching TV series, playing games, drawing, and doing some simple word processing."

"The tablet is too big to carry. The 8-inch size is just right. If the performance and battery life are good, I will buy one."

"I heard that Apple is also preparing to launch an 8-inch tablet this year, with the model number ipadmini. Four Star and Nokia also have plans to develop 8-inch tablets. This shows that 8-inch tablets are quite practical."

"I still like the standard version of the Ruida first-generation tablet. The 10.1-inch screen has better visual effects. The 8-inch screen is still too small, not much bigger than a mobile phone."

At the press conference, Qiao Ruida has already begun to explain the fourth product released today, a pair of small white split-type, semi-in-ear Bluetooth headphones, which appeared on the projection screen. They are light, delicate, and sci-fi in style, like a piece of exquisite art. Taste.

"This is the last product released today, the Reda AirPods Bluetooth headset. It uses the latest generation X1 Bluetooth chip independently developed by our Reda Technology, complies with the latest Bluetooth 3.0 specifications, and supports active noise reduction. Due to the use of the latest technology Manufactured, the power consumption of this chip is very low. With the support of a 100mah built-in battery, it can be used for 6 hours. Even if the active noise reduction function is turned on, it can be used for more than 4 hours. Used with the headphone charging box, You can charge it at any time and use it whenever you want, achieving more than 24 hours of battery life.”

The reason why this Bluetooth headset is called Reda AirPods is because the developer, Qiao Reda, had a bad taste and registered the name of Apple's Bluetooth headset. Who told Apple's AirPods Bluetooth headset product that according to the historical process, it will not be mass-produced until at least 2016? Now it has not even had time to register a name and trademark, and it happened to be blocked by Qiao Ruida.

The reason why this Bluetooth headset can achieve such incredible battery life is because the X1 chip uses a 5nm production process and is manufactured by the Ruida wafer factory. It has extremely low power consumption and extremely strong performance. Since the 5nm production line of Ruida Wafer Factory was put into production, it has been producing memory chips, including 2G, 4G, DDR3, and LPDDR3, with different sizes and models. After continuous optimization by Lin Mengsong, Academician Wang and others, the yield rate of the production line has increased to 30%, but it is still achieved by producing memory chips. They wanted to test the yield rate of producing other chips, but they were unable to find ready-made 5nm chip design drawings. After all, the current mainstream chip manufacturing process is still 28nm, and almost all EDA software does not support the design of 5nm chips. It is almost impossible to find a 5nm chip design drawing. The 5nmEDA software developed by the software team of Ruida Technology R&D Department is still under internal testing and has not been released to the outside world.

At a critical moment, Lin Mengsong remembered that the design drawings of several existing 5nm memory chips were produced by his boss Qiao Ruida. If he wanted other 5nm chips, he would definitely go to his boss. So Lin Mengsong called Qiao Ruida and explained the situation. Qiao Ruida casually sent him the design drawing of a Bluetooth chip she designed while testing the EDA software, and this is how she came up with this amazing X1 Bluetooth chip. However, Rockchip Wafer Factory has mastered the news of the 5nm chip production process, which is still confidential. Qiao Ruida did not present it at the press conference and introduced it in too detail.

Turning the PPT page, the charging box matching the Reda AirPods Bluetooth headset appears on the projection screen. Its rounded appearance and simple structure make it easy to understand how to use it at a glance.

"This is the charging box that matches the Reda AirPods Bluetooth headset. It has a 600mah battery installed inside, which can recharge the Bluetooth headset four times, and the charging time is controlled within 20 minutes. On the front of the charging box, there are three rows There are two battery indicator lights, two horizontal and one vertical. The two horizontal indicators show the power of the two Bluetooth headsets respectively. The vertical indicator lights show the power of the charging box. At the bottom of the charging box, there is a TYPE-C interface, which is the same as our Ruijie The charging ports of Da mobile phones are exactly the same and can be used with both charging cables and chargers. We will also include a 10cm long TYPE-C charging cable in the packaging box of the Bluetooth headset, which can be plugged into any USB interface. , to charge the charging compartment. Used with a 10W charger, the charging compartment and Bluetooth headset can be fully charged in 20 minutes.

Our Reda AirPods Bluetooth headphones have music mode, noise reduction mode, transparency mode and hearing aid mode. There are four modes in total, which can be switched by tapping the touch button above the right ear. The music mode is the same as that of common Bluetooth headsets. It simply connects to the Bluetooth signal and plays music. After the noise reduction mode is turned on, the earphones will collect external sound signals through the built-in microphone of the earphones, and then transmit them to the X1 chip for processing, and then play reverse sound waves to cancel each other out with the external sound waves to achieve the purpose of active noise reduction. The so-called transparency mode collects external sounds, converts them into electrical signals, and mixes them into the sounds played by Bluetooth headsets, thereby removing the headset's obstruction of external sounds. This function is suitable for turning on while driving or riding a bicycle. It is very practical to listen to music while driving without delay. The hearing aid mode is to further strengthen the signal strength on the basis of the transparency mode to achieve the effect of a hearing aid, which is very useful for some elderly people with hearing loss. "

With Qiao Ruida's introduction, a Bluetooth headset product with exquisite appearance, powerful functions and long battery life came to life on the paper. The reporters and friends at the press conference and the netizens in the live broadcast room were particularly excited. You know, active noise-cancelling headphones have always been the exclusive domain of major foreign headphone manufacturers. Noise-cancelling headphone products launched by headphone giants such as SONY, Monster, etc. are all high-end products, priced at least several thousand more, and are not very good. purchase.
