Compressed 16-bit RISC-V instructions compared to AVR

Since AVR uses mostly 16-bit instructions it would be interesting to compare with 16-b RISC-V instructions

RISC-V has compressed instructions extension C, which with a mere 400 gates added gives a RISC-V processor 16-bit instructions. I thought it would be interesting to compare these 27 instructions with instructions from the AVR microprocessor, a well-known processor for microcontrollers (used in Arduino). This will compare with a subset of the 78 instructions which…
