Interesting that Huawei have access to Armv9.2 for Cortex-A720 on Kirin 9000s ... I thought Huawei had lost it until v8
Also interesting that Cortex-X4 is not included in Kirin 900s, not sure the reason, whether consider is not needed or have no access to X4 or price wise is too expensive
Been posted on weibo. Here is the coverage of Tiantong-1 stellites, white operates in GEO
HW before HR
From Huawei's own paper,
it mentions VLEO in there, which I think is unlikely at this point.
But one thing for sure is that Tiantong-1 at GEO altitude? is too far away and can't provide the coverage needed. Chinese Starlinks can't get launched fast enough. If Huawei wants to really compete, it needs to be funding the Chinese starlinks program before Musk network takes over the entirely orbit
Weilai Capital increases its holdings of Jingzhan Semiconductor, Gallium Nitride has a bright future.
ecently, Suzhou Jingzhan Semiconductor Co., Ltd. underwent industrial and commercial changes, adding Hefei Jianjing Equity Investment Partnership (Limited Partnership) and Hefei Weilai Industry Development Equity Investment Partnership (Limited Partnership) under Weilai Capital as shareholders. At the same time, the company registered The capital increased from approximately RMB 74.59 million to approximately RMB 76.91 million.
Jingzhan Semiconductor is a professional epitaxy foundry providing GaN epitaxy solutions. In terms of power electronics, it mainly provides GaN HEMT epitaxial wafers on silicon wafers of various sizes, widely covering 200V, 650V, 1200V and even higher voltage application scenarios, and can provide depletion mode (D-mode) and enhancement mode ( E-mode) two epitaxial structures.
According to the data, gallium nitride has the advantages of wide bandgap, high frequency, low loss, and strong radiation resistance, and can meet the requirements of high efficiency, low energy consumption, and high cost performance in various application scenarios, so it has attracted close attention from the capital market.
At present, the application of gallium nitride is no longer limited to the consumer electronics market such as fast charging, but continues to advance to the data center, renewable energy and even new energy vehicle markets.

Because the US can't manufacture so-called "legacy chips" that they still need without it being astronomical in price. Ironic because the US needs a totalitarian state to break all Western labor standards so that they're cheap enough to produce and sell.
They are worried when China resolves the Taiwan and Korea question, then 60% of global supply will be cut off for US. Hence on-shoring as insurance, even if 30% more costly. What doesn't make sense is US sanctioning a world power like China to stop or slow it's development.
ARM including the v9 was available to Huawei until towards the end of 2022. I have posted here statements ARM made to the press before that, where they said all ARM versions including the latest were available to Huawei because they determined that ARM IP is of UK origin, not US. However towards the end of 2022 there were reports that ARM is going to stop selling to Huawei due to UK and US restrictions. So Huawei had plenty of time to license v9 Cortex cores as well as buy v9 architectural license. I don't know if they bought or not.

so, can we say that v9 is the last version Huawei have and no more?
I don't think that will be a problem. It would be several years before a new major architectural change is adopted for ARM. Apple still have not moved to v9. RISC-V is now an officially supported platform for Android and Debian. So, I believe RISC-V would have enough time to become mainstream before another ARM version becomes prominent.
