WebbAll arithmetic and bitwise instructions can be written in two ways: add t0, t1, t2. adds two registers and puts the result in a third register. this does t0 = t1 + t2. add t0, t1, 4. adds a register and a constant and puts the result in a second register. this does t0 = t1 + 4.

ALU Instructions can be divided in two groups: R-Type and I-Type. Four of those instructions make use of two special registers: LO and HI. They are internal CPU registers, whose value can be accessed through the MFLO and MFHI instructions.
