In MIPS add instruction : Its have format OPCODE | RS | RT | RD in mips , 1. SO it means ADD | $T1 | $S1 | $S2 , means ADD $T1, $T2 and store in $S2? because RD is destitation register? 2. But in assembly langauge ADD | $T1 | $S1 | $S2 means add s1, s2 and store it in $t1 I think right ISA IS ADD | REGISTER TO STORE DATA | OPERAND 1 REGISTER | OPERAND 2 REGISTER Please explain
