A modern history of VLIW should also include mention the Hexagon FSP architecture used by Qualcomm in its SoCs.
With a smaller target market it's probably more sustainable than Itanium was.

- chasil 3y agoSophie Wilson also mentions Firepath in several of her YouTube lectures.
- p_l 3y agoAlso, GPU VLIW architectures (including GCN and it's successors CDNA and RDNA) and yes, various coprocessors. Once heard comparison that Itanium was pretty good for a fast DSP, but too expensive XD
- MindSpunk 3y agoGCN is not VLIW (follows that neither is RDNA and derivatives). You're thinking of TeraScale, the generation before GCN, which was VLIW.
- p_l 3y agoMy bad - I misread a doc recently which implied otherwise, albeit that GCN used shorter ones. Just checked AMD docs straight and it was indeed normal scalar instructions. AIE and AIE-ML from AMD do use VLIW btw
