What is Qualcomm up to?
Qualcomm expressed an interest in RISC-V in 2017, and had RISC- V microcontrollers in itheir chips by 2019. I'd be staggered if they aren't busy developing some performant RISC-V silicon. They've had the time and have the expertise to design something better than any RISC-V silicon currently available, so why not launch it?
a) They don't consider the lawsuit to be anything more than theatre, and haven't actually developed anything. In that case, Quintaris would be nothing more than leverage against Arm.
b) They have some RISC-V kit, but it's either not very performant, or it's too power-hungry. They announced that they were designing RISC-V silicon for wearables a year ago - where is it?
c) They have the designs, but aren't realising them. Why? Customers and revenue. Qualcomm's fortunes are largely tied to Google's software. For whatever reason, Google has downgraded the development of Android for RISC-V - Android on Arm is the cash cow.
Of course, the same Qualcomm chips could just as easily run AOSP but - outside Chinese handheld hardware - shipping with AOSP-based OSs isn't done (ask yourself 'why not'.) Qualcomm's chips have also been open enough to be able to port a mobile Linux OS, which some OEMs, like Shift, have worked on to offer. That still seems niche though.
Plus, Qualcomm is about to enjoy a lucrative love-in with Micro$oft who, at last, seem to see the value in Windows on ARM.
What if Arm does win the lawsuit? Would that prompt Qualcomm go all-out on RISC-V? Would the consumer stomach a slightly cheaper device with mid-range specs and AOSP?
