@pir_at @risc_v @XilinxInc Now at 0.215 DMIPS/MHz by using libc version of strcpy and strcmp.
I've created a small @risc_v CPU: https://github.com/cliffordwolf/picorv32 … E.g. on @xilinxInc 7-Series FPGAs: ~1000 LUTs, fmax > 250 MHz, 0.124 DMIPS/MHz

1000 LUTs? So it should be fine on a ICE40HX1K or HX4K?

Xilinx 7-Series LUTs are more powerful than iCE40 LUTs. HX4K works but HX1K is not large enough.
