Somehow, they're also too stupid to roll their own.
- fuoqi 5y agoRussia has the Elbrus VLIW architecture, which is quite good with computations common in military applications (it has roots in specialized DSPs), so they are certainly not "stupid". But the problem is that developing an ISA is a relatively small part, most of investment and value lies in compiler and software infrastructure which can work with it. One of the biggest issues with Elbrus is the crappy proprietary compiler, which can not fully unlock the hardware potential. They also have to compile and debug Linux distributions and packets for thim themselves in-house, which adds to costs as well.
- jabl 5y agoA VLIW processor that suffers due to an insufficiently smart compiler? Gee, haven't heard that one before.
- jabl 5y agoThe whole premise of RISC-V is that the ISA itself is a commodity and there is no value in creating yet another proprietary ISA, so it makes sense to have it freely available to anyone and pool resources around the software ecosystem. So China/India/Russia/EU/whoever are in fact smart in choosing RISC-V rather than reinventing the wheel for no benefit.
