Reaching out to turn on the camera, Tang Jiayi looked up and asked, "Ready?"

"Hmm!" said Atletico's affirmative response from the other side.

"Okay, let's get started," the former picked up a clapperboard, reached in front of the camera, and clasped his hands together to hit the board, while shouting in a sinister voice, "action!"

There was a crisp sound from the clapperboard, and there was a clanging sound in the room, but it was Zhang Xuyao, who was sitting on the side, playing the drum.

Putting down the board, Tang Jiayi picked up the acoustic guitar next to her, skillfully hung it on her body and ran into the camera range to stand still, plucked the strings with her bare hands, and played the chords to keep up with the beat.

After the prelude, the "lead singer" Atletico finally went online and sang: "There are some things that I have forgotten, but I have been reminded by you,...... I said that in my storeroom, there is a bottle of all-purpose glue, which is best used to be different......"

The original song was only 170 seconds, and soon his singing came to an end, and finally ended the song "My Universal Glue" with "Good performance, this glued chip is very good, duang~".

At the end of the song, without waiting to put down the glue bottle in his hand as a performance prop, Atletico ran directly to the camera, intending to end the shooting.

"Knock knock!" suddenly sounded a fierce and urgent drum beat behind him.

"Don't turn it off!" Zhang Xuyao opened his mouth to stop: "It's not fun yet, let's do it again!"

Atletico looked at his wife, and Tang Jiayi also looked expectant, still maintaining a posture of preparing to play.

"Okay, you're the biggest!" Atletico had to nod their heads in agreement, and they came to help him, of course, to let them have fun.

As soon as I walked back to the position I had just stood on, a familiar prelude sounded in my ears, which was the accompaniment just now.

Turning his head to look to the side, "Why is this still the case?"

"You can sing something else, shampoo, skateboarders, I don't have a problem with that!"

Not wanting to lose the interest, Atletico still opened his mouth and sang: "When I first knew that I wanted to, when I made a shampoo commercial......"

Seeing someone touching his hair while singing, imitating the advertising actions of Big Brother Cheng, Tang Jiayi couldn't help but laugh and tremble, causing small noises to appear in the accompaniment. A little noise is not difficult for Atletico Madrid, the guitar melody is out of shape, and the singing voice in his mouth also changes, so that the performance fits the accompaniment perfectly, this time even Mr. Zhang can't help it, and he laughs forward and backward for a while, and the snare drum and copper cymbal are knocked by her indiscriminately, making a clattering noise.

Atletico Madrid is also very good, obviously the accompaniment music is no longer regular, he can still follow closely and send the rest of the lyrics out faster or slower. Although the song was unexpectedly messy and ugly, everyone still laughed and laughed at the end.

After this episode, everyone's interest suddenly dissipated a lot. Zhang Xuyao also wanted to try Atletico Madrid's singing skills, but Tang Jiayi stood on the latter's side and voted against, so she had to give up, went to the camera to read the material, and used her spoof spirit that was flooding on the tossing video.

As a 2-stop contracted podcast, she uploads a video of herself every week, and she also has herself in this video, so it's naturally no problem to publish it.

On the other side, Tang Jiayi poured tea for Atletico and herself, and asked, "Why did you suddenly remember to sing this song?"

In order to commemorate his first pair of "Meibang" skateboard shoes, Pang Mailang created "My Skateboard Shoes". This song didn't attract attention at first, until a two-dimensional UP master saw the MV of the same name and was impressed by his devil dance and introduced it as a "ghost animal all-star", which began to become popular.

Of course, the most popular are the secondary creations related to celebrities, such as "My Shampoo" starring Big Brother Cheng with Overlord Shampoo, and "My All-purpose Glue" performed by Atletico Madrid and the Beecore Family, all of which are Internet hits with more than 10 million online hits.

Due to the problems of cost and R&D time, the early bee core processors had to use SiP system-in-package, that is, the processor core, baseband, BDS navigation module, DSP digital processor and other functional chips were integrated in one package to achieve SoC (system-on-a-chip) functions, which are commonly known as "glue chips".

Although this saves development investment, it also causes the defects of too large packaging area and unsatisfactory performance, which leads to criticism from users, and then there is this "all-purpose glue". An UP master intercepted Atletico Madrid's voice and used human Vocaloid technology to cut and tune it by hand, allowing him to "sing" the song and successfully resonate with Bee users.

"All-purpose glue" has had a profound impact on bees and station 2, station 2 sells paid materials, and bees give up glue chips, which seem to be related to it. In fact, it's only the former that, and the 4xx bee core abandons the SiP package just because it can't be used.

Then, "the time has changed, it's time to pick up my glue bottle again," said Atletico, "and the next generation of cat10-level D10 baseband tape-out trial production is a step too late, and it is too late to load the 537, so it can only be forced into the 636." ”

"636?The next generation of mobile phone chips?I haven't heard you talk about it before?"

"It is the glue chip of beecore 626 and D10, the area of both has been reduced, and the packaging area and peripheral interface do not need to be changed. ”

The big ear 456 baseband integrated by Bee Heart 536/537 only supports 5 modes and 13 bands, and the bandwidth specification is only up to Cat6, which does not meet the latest storage requirements of the three major operators, and cannot sell mobile phones through operator channels.

The operator's financial strength is strong, and the rejection has a significant impact on the domestic sales of the product, and the result is that the Android camp manufacturers have abandoned MediaTek, which is not up to standard, and turned to Qualcomm. Bee mobile phone has its own system and services as a backer, and the situation is much better, but I don't dare to take it lightly. The reason why BP7 launched a full Netcom version equipped with Qualcomm baseband in the first half of the year, and B1 introduced a Snapdragon 820 chip to create a full Netcom version in the second half of the year, is to respond to the call of operators.

However, these are just emergency measures, the bee has its own baseband and processor, there is no reason to abandon it, and then there is a new generation of glue chip 636.

"D10 still doesn't seem to support CDMA, right?" asked Tang Jiayi.

"Well, I can only plug in. ”

"By the way, didn't you say that the 626 is a host chip? Why is it installed on the mobile phone again?"

Nodding and shaking his head, Atletico replied: "Not exactly, it's actually designed according to a general-purpose chip." ”

"In fact, the current situation is quite similar to the beginning," recalled the beginning, Ma Atletico said: "At that time, the bee heart team had just been established, although it got various IP core authorizations, but it was too late to integrate them into a single chip, so I had to produce them separately and make do with them first." Now that the team is mature, the production capacity resources are more tight, and the design and production costs are much higher. 626 is an all-round chip, which can be used by mobile phones and tablets, hosts, and servers, and can be used to the greatest extent and save money to the greatest extent. ”

"I knew you would say that, Ma Pick!" Glancing at the other party, Tang Jiayi said softly: "I still don't feel very reliable, mobile phones and game consoles are different in many places, okay? The heat is different, and the memory is not the same, do you plan to let the mobile phone use DDR4, or let the host use low-voltage memory?"

"Isn't it okay to support everything? Memory controllers aren't that complicated. The host uses a low-power chip, which can be silent and thin, and can also be casually packed into a backpack, which is also a variety of beauty to play. ”

"Okay, okay, you're an expert, you have the final say, anyway, it's you who mess up and lose people when the time comes. ”

"No, no!" Atletico finally summed up with a wave of his hand, "In the final analysis, the reason why we are confident in building the 626 into an all-round processor is because the process progress has increased the density of transistors, making chip design more free and loose. ”

"Alas, don't talk about this," Tang Jiayi sighed, and said with a wistful voice: "The change of mobile phones is really fast, how long has 4G been built, and 5G is coming again." ”

"Dear, 4G has not yet been fully built, and 5G has not yet come. ”

"What do you mean?"

"It's literal, the real 4G era has not yet arrived, and 5G is still being discussed, and it is expected to arrive in a few years. ”

"Then what's going on?" Tang Jiayi took out her phone and tapped it on the table.

"That's TDD-LTE, which can be called quasi-4G, and it's evolving to 4G, but it's not yet. ”

Tang Jiayi nodded clearly, "Understood, this is another 10 nanometer!"

Wafer fabs inject water into the gate-level width to better publicize, and operators call LTE 4G, also for better publicity. Because of the profits, the relevant manufacturers have also accepted this statement, and everyone happily played word games together.

"Sort of, although the water injection, 10 nanometers is still a little more advanced than 16 nanometers. Similarly, although it has not yet reached 4G, LTE still hangs 3G without pressure. ”

"Who said that?4G, oh no, it's LTE and you can't make calls yet!"

"Soon, the major operators will start testing VoLTE," Atletico said.

According to the definition of the 3GPP organization, 4G communication will completely abandon the original circuit domain core network that carries voice call services, and only retain the packet domain core network that provides data services, and the service will be fully IP-based and data-based, and 2G and 3G will be completely eliminated from then on, and all services will be completed only by 4G. The two LTE technologies are actually just a smooth transition to achieve 4G, which is also the origin of the name LTE (Long Term Evolution).

Obviously, the long-term evolution and realization of 4G require the efforts of equipment vendors, operators, and mobile phone manufacturers, and operators are unable to do without new technologies from equipment vendors.

This is the origin of the baseband problem: 4G has not really arrived, and the current equipment and technology still need to continue to improve, and if you can't keep up, you can only accept the bleak fate of being abandoned, which is applicable to equipment manufacturers, operators, and mobile phone manufacturers.

This kind of transformation is not easy for all parties, once and for all, it soars directly to 1Gbps, so that consumers really feel the horror of 'house returns to mobile overnight', and it is still a little difficult to use the method of phased improvement and upgrading, which is also the origin of the terms cat4 and cat7, which respectively represent 50/150, 150/300 peak download bandwidth, the unit is Mbps, and it needs to be divided by 8 when converted to network speed unit MB/S.

In addition to the increasing bandwidth, LTE is also enriching its functions. In the beginning, they could only be used to surf the Internet, and they automatically dropped back to 3G or even 2G when making calls. When the IP multimedia system (IMS) is built, voice and video calls (VoLTE and ViLTE) can be realized through the IP network, so as to get rid of the aging 2G and the growing weakness

"I really hope that this day will come soon, so that GSM can quickly withdraw from the network, so that there will be no pseudo base stations!" Tang Jiayi said with anticipation.

Fake base station group text messaging can no matter which user you are, as long as the GSM system of the mobile phone is active, it can connect to the mobile phone and send you a bunch of messy free text messages.

Shrugging his shoulders, Atletico grinned: "Things are not as simple as you think, on the one hand, there are hundreds of millions of feature phones on the market, they are still inseparable from GSM and GPRS, what should I do with this part of the 2G network withdrawal users? ”

"And VoLTE has high requirements for network hearing, it is equivalent to a line of Internet phones, if the bandwidth is not enough to call the card, it will be embarrassing. For mobile phone manufacturers, there is no difficulty in implementing VoLTE, after all, the operator has to bear the hard work, and the mobile phone side only needs to add the IMS protocol stack, and the workload is not too large. However, increasing bandwidth is a test of effort, which requires operators to transform and upgrade base stations, mobile phone manufacturers need to replace with more advanced baseband and RF modules, and also design antennas and mobile phone shells, if it is a metal back cover. Of course, a lot of testing and optimization is also indispensable, after all, none of these phones are sold to Africa. ”

"What's the matter with Africa?"

"It's nothing, I think of some of the deeds of our domestic counterparts, and I feel it. ”

"Huh?" Tang Jiayi showed an interested expression.

"The African and Indian markets are still the world of feature phones, India has a certificate that can toss and want to manage things, and the African side will herd sheep, and then there will be special African mobile phones that strictly implement local quality standards. ”

It is conceivable that this standard is obviously not too high, Tang Jiayi pouted: "These people are really, shameful and thrown abroad!"

"I know you will say that," Atletico Madrid looked very open, "as the saying goes, if you don't buy, you don't sell, unless you monopolize the business, the high price and low quality will not last long, and the most common situation is low price and low quality." It can only be said that this is an inevitable process, just like the counterfeits and piracy that were rampant in China before. ”
