Why does Qualcomm need this? They don't need to license RISC-V.
Is all the IP they acquired with Nuvia[1] tainted? Or were they just using ARM-derived internals?
From my understanding, just slapping on a different instruction decoder isn't a big technical hurdle. Actually, I wonder if it would be possible to design a chip with both an ARM and a RISC-V decoder on the same die and just fuse-off the ARM die on select units to avoid any fees...
