RISC-V is succeeding
The real reason RISC-V is succeeding, relative to ARM:<p><i>If you make your own CPU</i><p>- With ARM, You have to pay ARM for ISA license (after a several months long negotiation), and you cannot license your CPU design to anyone, as ARM has the exclusive right to do that with their designs.<p>- With RISC-V, you get a free ISA license, and you can license your CPU design to others.<p><i>If you do not make your own CPU</i><p>- With ARM, you can (after a several months long negotiation) license one of the few designs ARM has available. There&#x27;s no other vendors that can offer you ARM CPU designs.<p>- With RISC-V, <i>right now</i>, you can license any among hundreds of options available, from tens of vendors. The licensing process is usually very short and straightforward. Alternatively, there are some open hardware designs. You can get commercial support for some of them.<p>Frankly, unless ARM does radically change their business model, I do not expect them to survive.
