What about a 64-bit architecture for the Cortex-M market? If they could pull off some wizardry in focusing on energy efficiency, and maybe target peripheral functions involving GPU-like parallel processors for small-scale ML/AI/etc. purposes?
I dunno, it seems like there might be a market for that sort of thing. You train your model, pop it on a chip that consumes microwatts per megahertz? Something like that could be appealing.
It might also be impossible. I don't design chips. But I do think targeting both mobility and parallel processing could be cool. Maybe something like what Parallella is doing.

My last project used a 14 pin processor with 195 lines of bare metal C code compiling to 486 bytes of Flash memory and running on an internal 32Khz clock. This is more the target 8051 market though I must admit some cortex M0 processors are getting as cheap to use here. The Propeller Chip is awesome (no interrupts and 8 processors is a really cool concept) but at $8 it is going against the big boys (Freescale/ST/Microchip) with their more flexible memory, power management and rich peripheral sets. I would love for one of the big players to licence the propeller core but it wont happen.
- boznz 9y ago.. Forgot the propeller 1 core IS open source now and still no takers, real lack of vision out there.
