First RISC-V smartphones could launch in 2022

Sipeed recently tweeted a short video depicting its RISC-V RV64-powered smartphone prototype running Android 10. If all goes well, the Chinese company expects to release the first commercial models in 2022.

[...] The flexibility and ease of development brought on by the latest iterations of the RISC-V ISA have also been noticed by Intel and Apple recently, but this architecture seems more appealing to Chinese tech producers that intend to cut ties with the Western world and reduce reliance on US-owned patents as much as possible. To this effect, Alibaba already managed to port Android 10 on RISC-V about a year ago via the T-Head XuanTie board. More recently, Sipeed tweeted a video of what looks to be an Android 10 device with a 7-inch touchscreen powered by the XuanTie C901 board.

    How much will the ISA continue to resemble the RISC-V spec once anyone actually develops working devices for it? All the usual proprietary goop will immediately be crufted on.

    Too bad fabbing ICs at any sort of density is a real pain. Make a single transistor or even a simple IC like a 555 timer at home, sure--but ALUs, register files, RAM, and so on?

      Why do you care if a company adds changes to the ISA for *their* product?

      i agree, the "proprietary cruft" will add guaranteed "software decay rate".
      need surety people won't be using linux version 15 , 10 years down the road on the device they bought today ... to make phonecalls.
      then again, it's chinese and not from the " commonwealth of stoogy amerikan partners"?
      one can hope ...
      also, anyway to run/convert android apk to jars that can be executed by openJava maybe?
        would be cool if we could ditch the whole android HAL altogether and rely on the linux kernel instead?

      rant: i know my note2 hardware sensor isn't going to magically improve with a updated os version but i don't understand why android 10 cannot access it ... for example.

        correction:
          note2 *GPS* hardware sensor.
        if you want better, more accurate hardware you HAVE TO buy new hardware ...

      In this era of ultra cheap microprocessors, who needs a 555 timer? Well, other than it's 200 ma current output which is better than most GPIO pins.

      In the future: oh, yeah. Long ago we replaced our 555 timers with microprocessors. First the program tests the capacitor and resistors to calculate the time delay and adjust the Blink sketch parameters and recompile the sketch. This then runs on an Arduino emulator written in JavaScript on Node.js on Linux. We no longer needed a special fabrication line for special purpose chips like the 555.
