Roger that :-) I was thinking about experiment like in "Sphery vs. Shapes" to convert NuttX code to FPGA LUT directly with no CPU.. but if that makes no sense then probably Open-Source RISC-V would be the best choice and there are some ready to use implementations that could constitute our reference NuttX@FPGA design.. the goal here probably would be to run on smallest possible LUT count or something with amazingly better performance than out-of-the-box hardware? :-)
