You’re suggesting that Snapdragon processors would switch to RISC-V and that would be no big deal? Presumably Qualcomm is committed to numerous multi-year supplier agreements for the arm chipsets.
- monocasa 2y agoThis affects their custom Nuvia derived cores. I'm sure Qualcomm will be able to keep using ARM designed cores to cover themselves while they ween off ARM in favor of RISC-V if they need to.
- hajile 2y agoQualcomm pitched Znew quite a while ago. It mostly ditched 16-bit instructions and added a bunch of instructions that were basically ripped straight from ARM64. The idea was obviously an attempt at making it as easy as possible to replace ARM with RISC-V without having to rework much of the core. https://lists.riscv.org/g/tech-profiles/attachment/332/0/code_size_extension_rvi_20231006.pdf https://lists.riscv.org/g/tech-profiles/attachment/332/0/cod...
- snvzz 2y agoAn attempt that failed miserably. (it was formally rejected a year ago) But, by now, it is expected that Qualcomm's RISC-V designs have been re-aligned to match the reality that Qualcomm does not control the standard.
- dwaite 2y agoActually, it was an attempt to reuse as much of the ARM design they got when they bought Nuvia moving to a different CPU architecture. They were worried about ASIC design not software code.
