In 2014, Xiaomi took over lc1860 from Lianxin, named Xiaomi surging, and began to develop its own chip, but it was silent after the release of the first generation of products. In the middle of the rumor there is surging S2, but did not see the product.
it was the end of 2014 and the beginning of 2015 for Xiaomi to take over the chip design from Lianxin. At that time, the growth of Xiaomi’s mobile phones doubled every year. Judging from the momentum, Xiaomi’s mobile phone can support its own chip research and development.
at that time, Huawei Hisilicon had its own chip design, and domestic manufacturers such as Spreadtrum and Lianxin also had 4G baseband chips and application processors. Xiaomi tries to introduce chip design. On the one hand, it hopes to reduce costs, on the other hand, it hopes to play a domestic brand and compete with Huawei Hisilicon.
However, Xiaomi’s mobile phone does not last long. In 2015, the mobile phone brand began to upgrade, and the brand image of Xiaomi’s low-end brand limited its development. Millet’s domestic sales began to decline. Although the Indian market has greatly helped Xiaomi, it is difficult to support its own research and development of mobile phone SOC at this scale.
at the same time, Xiaomi’s research and development is not smooth. Surging S1 chip is basically lc1860, successfully installed. Although the efficiency and heating, cost are not ideal, but it is officially commercial.
what’s worse, in the 5g era, the threshold of 5g baseband research and development is very high. At the beginning, only Qualcomm and Huawei, and later Samsung, MTK and Spreadtrum solved the 5g baseband problem. When Xiaomi took over the chip design from Lianxin, Xiaomi only had 4G, and huge investment was needed to develop 5g. However, it is difficult to see achievements after investment.
the reason why Huawei Hisilicon can operate is that Huawei mobile phones, Huawei TVs and Huawei tablets support Hisilicon almost without other chips. Relying on hundreds of millions to support the cost of Hisilicon research and development.
Xiaomi is the customer of Qualcomm and MTK, which firmly occupy most of Xiaomi’s products. Surging S1 only tested a model, surging S2 even if the tape is successful, the development is successful, there is a million level of volume is also the sky.
in the case that the core is authorized by arm and the manufacturing is done by TSMC. Both Qualcomm and Hisilicon share the R & D cost by hundreds of millions of volumes, and Xiaomi can share the R & D cost by one million at most. How can performance compete?
what’s worse is that Xiaomi’s own SOC of mobile phones faces conflicts with Qualcomm and MTK. As an important customer of Qualcomm, Qualcomm will not like Xiaomi to make its own set. Xiaomi must have a good relationship with Qualcomm in order to get a high-tech chip. It’s not worth the loss to make your own SOC.
Xiaomi is now an important Internet TV manufacturer. At present, both high-end and low-end TVs, except Huawei, are low-cost chips of MTK and MSTAR, several generations behind mobile phones.
compared with mobile phones, the biggest difference between TV and TV boxes is that there is no baseband. 5g baseband, the biggest problem, can be solved, and the R & D cost will be much lower.
Xiaomi surging, as long as he gets the authorization of arm, uses the A55, A78, X1 cores of the public version of arm, and uses the Mali graphic core of the public version of arm, as long as he is willing to stack, he can stack high performance.
this means that Xiaomi can stack enough CPU and GPU cores as long as he wants to, so as to obtain performance several times higher than that of mobile phones, and the performance is continuous.
with two high frequency X1 super cores, two A78 large cores and two A55 small cores, Mali g78 is stacked with 24 and pulled to high frequency. All kinds of dynamic compensation of smart TV chip are inserted into the frame IP. Use the radiator on the top of the Yellow boss tactics nuclear card.
this chip can be used in Xiaomi’s high-end smart TV. It can be made into a high-end TV box with low delay Bluetooth (fever players can use USB cable) game handle and keyboard and mouse. TV can play directly. Is it not fragrant?
when designing this high-performance box, rich interfaces should be reserved. What analog audio ports, USB, HD Mi makes an analog output switch.
when this box is used for office work, its performance is much higher than that of the Kunpeng 920. The core performance of the Kunpeng 920 is comparable to that of the A76. The A76, a77, A78 and X1 are several generations inferior.
add batteries to this box, add a screen, a keyboard, a touch pad, and install UOS to make a notebook computer with independent information security.
reduce the CPU frequency, shield the GPU core, set up a power consumption wall, add batteries, screen, and camera, which is a high-performance flat panel.
at present, chips of high-performance TV, tablet, box and information security computer are basically blank. Xiaomi itself has a TV, tablet box, computer product line. Develop strengths and avoid weaknesses to form scale. Xiaomi has a way out.
