In recent years China has made significant strides in developing its own semiconductor industry with things like Huawei's HiSilicon, Loongson, StarFive, MilkV, etc. I would call that China outlasted the US sanctions barrage from the US. Chinese investment in fabrication technologies, while not anyway near cutting edge is getting to be near good enough. With things like Intel looking shaky and the rise of Risc-V and ARM we are steadily moving forwards towards the hopeful future of open standards, hardware and software, where most consumer computation devices will have built in Chinese backdoors instead of American ones.

https://leftypol.org/tech/res/10230.htmlThe lack of Intel ME style backdoors in the RISC-V CPUs we've seen so far is encouraging. RISC-V laptops still seem some ways away. As soon as some decent ones appear I'll probably ditch my old ThinkPad. The only "missing piece" is a libre WiFi card
I was under the impression China made great advances in ARM microchip manufacturing, but if they choose to pivot to RISC V, the future looks bleak indeed. There is no lasting place for a braindead C-machine of an ISA outside the embedded space. It needs extensions even for relatively basic operations and takes three instructions just to calculate the overflow of an addition (which may also branch and allow for side channel attacks on cryptography btw).
>>26473with ARM you become a license cuck. also according to one answer here you can get carry out but it wrecks your pipeline:

classic dunning-kruger tor post
>>26473>China made great advances in ARM microchip manufacturing, but if they choose to pivot to RISC VThey are doing ARM, but I guess when it comes to PCs they are building their own custom software stack on top it anyway and they can leverage it on the internal market. With ARM while it has better linux and now some shitty windows support you still would be bound to ARM licenses. So custom RISCV is the safe bet? If I recall Harmony has nascent RiscV support so it's future is not just linux based.
Didn't they had some beef with Arm that ended up with Arm's Chinese branch going rogue?
>>26486>If I recall Harmony has nascent RiscV support so it's future is not just linux based.The MIPS family serves as the blueprint for the future of RISC V, previously being the most conceptually clean RISC architecture in the industry. As opposed to PowerPC, SPARC and Alpha having had niches in the pc and server markets, MIPS only saw ever saw use in SGI servers and workstations. MIPS processors where always mainly used in the embedded space and are still predominant in some niches (routers for example) because of cheap licensing and legacy.
Made in China 2025, next level of Chinese copium. Just give it up dawg

I say that China's latest is only seven years behind AMD and Intel and can pretty much do everything performance wise that it needs to.
it's too bad that trump is too much of a chicken to actually slap a tariff on taiwan but god imagine the possibilities
>>26471>China>open standardsThese two do not combine.

Is there anything to point at this not being wasted effort barking up the wrong tree like MIPS before it? The parallels are pretty obvious, both are teaching ISAs getting horribly mutated out in the wild. The advantage is that every computer engineering graduate has implemented RV32I in their coursework not that the architecture itself is well designed. I've yet to see a superscalar RV processor you can put your hands on as a regular person or the HPC accelerators people have been teasing for 5 years.
>>28665>I've yet to see a superscalar RV processor you can put your hands on as a regular personI'll eat my hat on this. Seems like the spacemit K1 and M1 as well as the newer sci-five SoCs are OOO.
>>28665Maybe if were to assume that the end goal is desktop-class R-V CPUs, whereas the more likely goal is having something between an FPGA and an off the shelf ARM SoC as a middle ground for custom chips controlling all the various IoT devices, drones, autonomous systems, etc that China actually produces
Why do you need a list of approved CPUs?
I work at a hardware company. one year ago we were talking about partnering with Chinese companies, now red scare is in full effect and my boss tols me npt to go to china "because they'll detain u" jokes on him I'll go anyway and just not mention it.
>Huawei Technologies has applied for a patent in “ternary logic”, an alternative to binary computing logic first explored in the former Soviet Union, in hopes that it could improve the design of artificial intelligence (AI) chips and help mitigate the impact of US sanctions
>The approach could be used to reduce the number of transistors on a chip and therefore reduce energy consumption, according to the patent application, which comes at a time when advanced chip designs at the 2-nanometre level are approaching physical limits.https://www.scmp.com/tech/big-tech/article/3305201/tech-war-huaweis-ternary-logic-patent-could-solve-problem-power-hungry-ai-chipsThey got through the noise problem. A step towards bridging the digital and analog.
What's even wilder is that HarmonyOS has apparently had a ternary logic support for years.
