verditelabs··on Qualcomm’s Hexagon DSP, and Now, NPU
Oh yeah, I specifically worked on HMX stuff and I don't even know. I stopped caring about keeping up with product names when we stopped using names from LOTR for our internal projects. I wish they would reveal _something_, because currently it's a bit of a black hole on my resume

Qualcomm's naming schemes are so confusing: I used to be on the QCOM Hexagon compilers team for a few years and I still don't know what hardware unit the NPU is. Is it Hexagon Matrix Extensions(HMX)?

I am an ex QCOMer and agree with everything here. We always said it was a legal firm with a tech problem. That stranglehold on IP really holds the company back, IMO. Sure the licensing model made $$$ but they lose a lot of good will in the tech community.

I used to work with the Halide guys from 2019-2021; I was on the TVM team. The compilers group was very proud of Halide's success in the early pixel phones. That was the library behind HDR+ on the Pixel 3.

Hexagon is a difficult architecture to write code for but the benefits are worth it: it's the secret sauce for why Qualcomm's modems are so good. I see people getting all excited over AVX512 and I just think "well we had 2048 bit vectors years ago"
