WebbSo in the ALU instructions group we will find those instructions that do this kind of operations. 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.
