The original Adreno GPU was a blend of Qualcomm's never-productized QShader architecture and AMD's handheld GPU, which was based on the original XBox GPU. The programmable shader core came from Qualcomm and the fixed function blocks came from AMD.

The Bitboys folks were terrific, both software and hardware, but they were not the only people working on this, or even the majority IIRC. I mis dearly working with them.

Eventually, this combination of former Bitboys, AMD and Qualcomm folks, working from different sites around the world and with vast cultural differences resulted in a lot of internal politics and we lost many great people.

Thanks for sharing, I had no idea! It'd be really interesting to hear more about that era.

Don't forget Falanx from Norway. They were acquired by ARM, turning into the Mali GPU.
