China Plans National, Unified CPU Architecture
MrSeb writes "According to reports from various industry sources, the Chinese government has begun the process of picking a national computer chip instruction set architecture (ISA). This ISA would have to be used for any projects backed with government money — which, in a communist country such as China, is a fairly long list of public and private enterprises and institutions, including China Mobile, the largest wireless carrier in the world. The primary reason for this move is to lessen China's reliance on western intellectual property. There are at least five existing ISAs on the table for consideration — MIPS, Alpha, ARM, Power, and the homegrown UPU — but the Chinese leadership has also mooted the idea of defining an entirely new architecture. What if China goes the DIY route and makes its own ISA or microarchitecture with silicon-level censorship and monitoring, or an always-open backdoor for the Chinese intelligence agencies?"
This is probably among the worst ideas I've ever heard. They're basically saying "Standardize at the cost of having different architectures that are superior in their own ways", which is just absurd.
Are there 2 billion consumers in the marketplace who will purchase goods and services related to that arch?
Alternatively: Does a bear shit in the woods?
Just from the top of my head:
They could include device/code authentication on-chip --> no more anonymity + only run approved, signed software
If hardlinked to specific NIC --> govt owns your device, no more privacy.
Politics (and spying) aside, this is probably not unlike their past effort to create a new Audio Video compression Standard. I'm sure the Chinese look at the Arm ISA situation and see wow, you really do have to get an Arm license if you want to make a smart phone. This seems similar to the BluRay MPEG/H.264 situation and their move with AVS. They've got a lot of smart folks in China and want to spur development. In the process, the want to see if they can give their local companies an economic advantage (reduced licensing fees for manufactured products for domestic consumption).
If this takes off in China (a big market), then instead of chinese companies paying foreign companies a licensing fee for products (net outflow of money), the foreign companies that want to make a product for consumption in the chinese market will probably have to pay the Chinese licensing fees for this. That way money for new development gets to stay in China benefiting their economy more than others. Why wouldn't they want to do this?
Of course if it makes it easier to spy on folks, so much the better (homogenous platforms make that easier), but I don't think that's the main motivation. As with most things in China today, the motivation is national economic self-interest.
Interesting how most comments wank on about fears of backdoors.
How stupid do you think the chinese are? A hardware backdoor in every device means that if you lose control of it even once, your entire infrastructure belongs to whoever you lost it to. I don't think anyone would take that risk for a bit of spying, not if you already have 100 better ways of spying.
What is so unlikely about the assumption that it really is in order to become independent of the west? That's a biggy right there. There's an elephant in the room, you know? The chinese are fast becoming one of the most important players on the world stage and they can't have something as important as chip design rest with a country (USA) that might turn hostile at the next unpredictable election.

What are you talking about? There are literally dozens (maybe hundreds) of different types of screws alone, engineered vastly different from one another to be best at their application. Wood screws are much different from sheet metal screws which are much different from concrete screws, phillips-head versus flat-head versus torx versus proprietary heads...
Everything from the length of the screw, the spacing of the threading, whether it's self-tapping or not...they're all engineered to be best at a particular application. Once you extend the set to include fasteners of any type, there are probably a million different types, be it mechanical, chemical, magnetic...
Try drilling a flat-head sheet metal screw into concrete. That's pretty much the same result you'll have trying to shove a one-size-fits-all CPU into every embedded computer system in the nation.
... a unified architecture could make it easier to build in a common backdoor for spying ...
I doubt its over surveillance, such a backdoor will be found. The real motivation is most likely economic, simply not wanting to buy an expensive part from the west. It may even become a part they could export. Do consumers really care, or even know, what CPU is inside some electronic appliance/device?
