It seems pretty easy to come up with a | processor design that is competitive in low-compute load | applications, but what about more advanced designs? I'm curious | what it is that ARM brings to the table there and if there is a | chance that RISC-V will ever offer serious competition. | | Certainly RISC-V does not need to be the best to survive as a | viable option for most designs. It may absorb a lot of market | share from ARM in the long run. It will be interesting to see how | it develops. | TimSchumann wrote: | I'd say that depends on the higher end of what? Control over | the firmware, understanding of the actual bits you're flipping | and the architecture, power consumption, or raw computer per | clock? | mastazi wrote: | I'm not parent but personally I'm interested in performance | per Watt | ape4 wrote: | No integer overflow instruction I read on Hacker News the other | day. | azhenley wrote: | I've had a lot of fun learning RISC-V assembly off and on over | the last year.
