What is MIPS?       Operation Codes

Some Examples   Applet to Run your MIPS Code   

- opcode: partially specifies what instruction it is z
Note: This number is equal to 0 for all R-Format instructions.

- funct: combined with opcode, this number exactly specifies the instruction

- rs (Source Register): generally used to specify register containing first operand

- rt (Target Register): generally used to specify register containing second operand (note that name is misleading)

- rd (Destination Register): generally used to specify register which will receive result of computation
