Provide the instruction type, assembly language instruction, and binary representation of the instruction described by the following LEGv8 fields:

op = 0x458, Rm = 14, Rn = 16, Rd = 18, shamt = 0

Solutions

Expert Solution

Instruction type: R-type (refer below)

Assembly language Instruction: ADD X18, X16, X14 // (since, opcode 0x458(hex) = 1112(decimal) which is ADD arithmetic operation)

// register X18 contains the sum of the contents of X14 & X16 (refer below)

Instruction

op = 0x458(hex)

(11 bits)

Rm = 14

(5 bits)

Shamt=0

(6 bits)

Rn =16

(5 bits)

Rd = 18

(5 bits)

Decimal represntation 1112 14 0 16 18
Hexa decimal representation 0000 0000 458 0000E 000000 00010 00012
Binary representation 100 0101 1000 01110 000000 10000 10010
