in this case the instruction set is extremely small (and includes open source verilog, so you could even fab it yourself)
quote from the website:
https://developer.arm.com/documentation/dui0646/c/The-Cortex-M7-Instruction-Set/Instruction-set-summary
So is the Cortex M7. The entirety of the M0+, M4, and M7 microcontroller cores are very, very small ARMs.
Hmmm. Okay, so its an FPGA Risc-V then.
That's kind of sad, that means there's no hope that its as power-efficient as a proper ASIC core like ARM-M7.
