MIPS Assembly Language Q1 The operation performed by the ALU

MIPS Assembly Language.

(Q1) The operation performed by the ALU, in case of an R-Type instruction, depends by a specific amount of bits. How many?

(a) 6

(b) 8

(c) 12

(d) 2

Solution

ALU operates on data from register file using the funct field of the MIPS instruction (Bits 5-0) to help select the ALU operation.

Therefore, the amount of bits is: 6.
