15.3.2

Computational Instructions (Table 15.3.2)

Computational instructions perform arithmetic, logical or shift operations on values in registers. This

instruction format can be R-type or I-type. With R-type instructions, the one or two source operands are

computed and its result is saved to one destination register. With I-type instructions, one of the operands is

16-bit immediate data. Computational instructions can be classified as follows.

•

ALU immediate

•

Three-operand register-type

•

Shift

•

Multiply/Divide
