ARM/MIPS openness

post #1 of 2
Thread Starter 
I'm a bit confused about the "openness" about these ISAs. I know that you apparently have to pay royalties/get licences but what exactly are these fees for? I know that both sell micro-architectures and IIRC processor designs, are the royalties/licencing fees only for these? Or does one have to obtain a licence even if they build an ARM/MIPS chip from ground up?

I was curious about these two ISAs in particular because they, at least for the time being, are the only viable alternatives for x86... I wonder how easy it would be for a start-up to get into the processor business.

Oh and what about PowerPC?

I think that it would be rather difficult to get into the processor business. For one you need tons of capitol for research and manufacture facilities. then you need a large team of highly skilled electrical engineers. The royalty/fee is likely for copyrights and patents on various architectural pieces, a lot of intellectual property is wrapped up in those chips. If you attempt to build the chip from the ground up without a license unless you completely reinvent everything you run a serious risk of copyright/patent infringement and being sued. Especially since Apple now bought ARM and as we have seen with android tablets apple does not hesitate when it comes to enforcing patent laws.
