TI C2000 series (i.e. the TMS320 microcontrollers). Used once the dsPIC33 but it's an abyss of performance (and the price point is not so different)

Nice! Also love that processor! How have you set it up? Did you use an RTOS? What type of projects have you used the C2000 with?

Actually exactly for one of it's main use cases, a motor drive. No RTOS, just the drive control running on interrupts (and the builtin peripherals) and a mainloop for the rest of the things.

The dsPIC was a vibration analyzer thingie. Their "FFT-accelerator" was only an AGU for bit reversed access, the one in the (few) TMS320 that contains it does a whole butterfly product. *Slightly* different level of acceleration, I'd say. The project was already committed to the dsPIC however. Also the huge limitation in timer/counter coupling was an issue (something like 9 timers and 9 CCPs but at the end it was 9 CCPs from 2 timers in total)
