Coquettish Rebirth

"The most important feature of the chip developed by INVISTA is that it is aimed at a mobile product giant like Huaxia Hi-Tech. Therefore, the most shining advantage is that the power consumption is extremely low!" Lao Huang said in the conference room of Huaxia Hi-Tech. While showing the ppt slides made by Invista, they proudly introduced loudly, "Everyone should know that in the current market, the main supplier of embedded display chips is the British Imagination Technology The company, referred to as IT, also has Intel's onboard chipset and via VIA's onboard chipset. But the products made by the latter two are basically for notebooks and desktop computers, and the power consumption is definitely not what mobile phones can use. And The products of IT company in the UK have insufficient performance. However, the products made by INVISTA are completely different! In the case of greatly reduced power consumption, the power consumption guarantee is only half that of IT in the UK under typical working intensity. Next, we achieved maximum performance..."

I have to say that this old Huang is really a natural speaker.When he speaks, it is definitely inspiring!That confident look, that red-faced loud voice, definitely conveyed the confidence in his heart to everyone present!Even though Jia Hongjian knew that there might be some exaggeration in what Huang said, he still felt encouraged and eager to try!Lao Huang said this, and then they will show their ppt slides in detail.On these slides, various data such as their craftsmanship and performance are written, which is really a bit reasonable and convincing! "The -go-7000m is a highly integrated mobile media applications processor that combines the flexibility of highly optimized DSP technology with controlled acceleration for the ultimate in power optimization. More than any other application processor on the market Power consumption is 50% less. nvidia--go-7000m provides rich multimedia features for the mobile entertainment and communication market, enabling mainstream users to have longer battery life, so that consumers can enjoy more fun." "Our 7000m The graphics card chip has a dedicated high-performance 350mhz arm1176jz-s core. It adopts TSMC’s 90nm technology foundry, shares up to 256m video memory, supports Microsoft x9.0 and opengl2.1. The peak fill rate can be as high as 0.7g pixels per second, and 0.7g Texture per second. It can be said that the power consumption is extremely low under high-performance computing, and the performance is very powerful. Under vga resolution, h.264, mv9/v-1, and mpeg-4 format output can reach 30 frames per second, that is, it supports 480p resolution video capture at a rate of 30 frames per second, and supports up to 1 million pixel camera sensors, supports all available DRM formats, fully integrated, high-quality analog audio subsystem, In the end, a TV encoder and video da are also integrated. That is to say, theoretically, after installing such a chip of ours, you can watch TV programs directly on the mobile phone through the Internet...Of course. It is a TV program with unlimited transmission... Finally, if we use such a small chip with dedicated gddr2 video memory, the basic performance can reach 2004% of the performance of the mid-to-high-end discrete graphics card gf6000 series released in 60!"

I go!At that time, Jia Hongjian was really excited when he heard this!If such a level can really be achieved, it means that in terms of hardware level, it can really play World of Warcraft on a tablet like Huaxia Hi-Tech, and it can also drive high-efficiency and so on!How does your sister feel?And even if you play games like Lineage 2, the picture can be adjusted very well!This performance is really good!It can reach 60% of the performance of the mid-to-high-end discrete graphics card two years ago, which means it is almost the same as the low-end discrete graphics card back then, and it is now an entry-level discrete graphics card.This integrated graphics card can achieve the same ability as an entry-level discrete graphics card. Although it seems normal, don't forget the reason for power consumption!In history, this old Huangkeng Xiaobai time.For graphics cards such as gtx610, it is not necessarily that Intel's core display is powerful, but Intel's core display also needs a power consumption of 8 watts to 10 watts!If the power consumption of this old yellow can be controlled to only 3-4 watts of the graphics card.That is definitely a big step forward!At this time, it can be said that Jia Hongjian is really optimistic about Lao Huang's graphics card!He immediately asked Lao Huang to find TSMC chips and try to make a few chips for Huaxia Hi-Tech to test.Hearing such a request from Jia Hongjian, Lao Huang immediately contacted TSMC and asked them to prepare tape-out immediately.

Taping out of this production line is also very simple.After a little preparation, TSMC immediately taped out dozens of INVISTA chips for testing.This tape-out, in the field of chips, refers to small-scale production, also called trial production.On the one hand, let the manufacturer be familiar with the various processes of design.On the other hand, it is also for design manufacturers to see if there is a problem with their design—if there are potential bugs, or if the process design is not so perfect.Mass production is about to start, it's too risky!like intel pu.Anyone who is familiar with it knows that this pu has a thing called stepping, which is equivalent to a "version".The later the version is, the more perfect it is, the less problematic it is.And every time a modification is made after the tape-out, the step-by-step version needs to be modified. A small modification is from a0 to a1 without modifying the previous letters, but only the following numbers, and a major modification is from a0 to b0. of.And some pus are all 1 or 2 versions, and even the step-by-step version of pus are all up to e!

So from such a perspective, this stream is absolutely necessary!TSMC's tape out is also quite fast, a total of one week's work, and this stupid Taiwanese has successfully taped out.After Jia Hongjian and the others got the chips that INVISTA successfully taped out, of course they immediately started testing.First of all, the performance of such a chip from INVISTA is really good!For example, Lao Huang advertised that the camera supports up to 1000 megapixels, and that the recorded video with 640x480 resolution can reach 30 frames. These hard data are really easy to achieve.As for the soft data, I have to say that it is still a little watery.For such a chip, the frequency is actually 350mhz, so it is actually slightly worse than the current entry-level independent display.Although from the various data of the previous publicity, it seems that such a chip is really invincible, but the performance of the desktop discrete graphics card produced by the same version of the chip and the discrete graphics card on the notebook can be quite poor. Woolen cloth!Not to mention that INVISTA's graphics card chip is a low-voltage and low-power version specially made!

Although it is said that the performance is a bit watery, there is not much water, about 20%.If such a graphics card is placed on the motherboard, with such a power consumption of 4-5, it is still possible to watch DVDs and play small games, and the power consumption can even be as low as 2-3 tile levels!This also means that if the pu and the gpu are combined, and the screen is used to watch dvd-resolution videos together, it can be watched for 3-4 hours no matter what.Such a level has caught up with the Android tablet in history!After many Android tablets in history have been used for a long time, they are still at such a level!From such a perspective of power consumption, Jia Hongjian really thinks this GPU is pretty good!

It can be said that whether such a tablet project can be completed now is to see how the modification of VIA's 7m is. If they modify it well, then such a tablet can still be made within this year!Soon, the people from VIA modified their chip and it was almost modified, and then went to tape out, and then the chip was sent to Huaxia Hi-Tech.After another test this time, I found that all the indicators of this pu are very good!After being limited to 800mhz, the power consumption has further decreased, and the average power consumption of the overall work has been reduced to the level of 4 watts. Although it is still a bit far from the expected 3 watts, the level of 4 is also quite good, plus the typical performance of the GPU. If the consumption is 5 watts, the two add up to 9 watts.As for the screen, if it is counted as a 10-inch screen, even if it is made into an LED screen, the general power consumption is basically 2-3 watts.This adds up to a level of 11 watts to 12 watts, which means that basically three batteries with a total of 12000 mAh are installed. If you use it to watch DVD-level videos, you can watch for four hours.

Is such a data acceptable?Even if it is playing games or something, playing for 4 hours in a row is definitely interesting, right?And don't forget that this is only 2006, and the various chip production processes used are still 90 nanometers!The higher the process level, the smaller the number of nanometers, which actually saves more power!Maybe after 5 years, just use 28nm technology to produce it, and you can keep the pu at the highest power of 3!But now, after all, it is impossible to do so.And if our product is really the first in the world, other consumers have no place to compare it, and people don't know whether the length of these four hours is long or short, at least it looks longer than a notebook, doesn't it?Laptops can’t stay on standby for 8-10 hours like our tablets, right?When we are in standby, we can turn it on anytime by pressing the power button!

Thinking that the PU is acceptable, and the GPU is also acceptable, Jia Hongjian started negotiating the price with both parties.Although both parties have a cooperative relationship, they are still independent companies anyway, and the price still needs to be negotiated.However, after asking about the price, Jia Hongjian was quite surprised. The pu costs about 1500 yuan, and the gpu costs 1200 yuan...that is to say, the sum of the two alone will cost 2700 yuan?
