Is the MIPS instruction not I type or R type instruction?
When talking about sign-extended instructions I think of the I-instruction (beq, bne, addi, etc) if I am correct, but I am not sure if the MIPS instruction NOT is I type or R Type

There is technically noNOTinstruction in MIPS.NOTis a synthetic instruction. Convert it to an actual MIPS instruction first.

NOT is a pseudo instruction that inverts the given input. I believe the real instruction is a logical operation with the zero register which is R type.
