What about the MIPS instructions is correct?

Question

In which of the above instructions is done writing in a register?

a) lw
b) bne
c) beq
d) sll
e) sw
f) add

I'm sure for d) and f) but I also think that a) and e) are correct. What do you think?

SO is not a homework service. Please see [ask]. Concerning your problem, you miss a obvious one. And what is a register? Is PC a register? Maybe this will add extra yes answers? — Alain Merigot, Jun 25 '19 at 20:10
In general register, not specified which type...Just that writes in register. — Viktor, Jun 26 '19 at 02:57

So Think about the general 5 stage pipeline used in MIPS F,D,E,M,W. (fetch, decode, execute, memory, write)

lw -> you are LOADING something from memory into variable (ends in write) sw -> you are taking a variable and writing into memory (ends in write)

No. only the LW. LW writes to a register. SW writes to memory – Mango Jun 28 '19 at 18:55
