Function

DIVXS

B/W

Rd ÷ Rs

→ Rd

Performs signed division on data in two general registers: either 16 bits

÷ 8 bits

→ 8-bit quotient and 8-bit remainder or 32 bits ÷ 16 bits → 16-bit

quotient and 16-bit remainder.

CMP

B/W/L

Rd – Rs, Rd – #IMM

Compares data in a general register with data in another general

result.

NEG

B/W/L

0 – Rd

→ Rd

Takes the two's complement (arithmetic complement) of data in a

general register.

EXTU

W/L

Rd (zero extension)

→ Rd

Extends the lower 8 bits of a 16-bit register to word size, or the lower 16

bits of a 32-bit register to longword size, by padding with zeros on the

left.

EXTS

W/L

Rd (sign extension)

→ Rd

Extends the lower 8 bits of a 16-bit register to word size, or the lower 16

bits of a 32-bit register to longword size, by extending the sign bit.

Note:

Refers to the operand size.

B: Byte

W: Word

L: Longword

Logic Operations Instructions

Instruction

Size*

Function

AND

B/W/L

∧ Rs → Rd, Rd ∧ #IMM → Rd

Performs a logical AND operation on a general register and another

general register or immediate data.

B/W/L

∨ Rs → Rd, Rd ∨ #IMM → Rd

Performs a logical OR operation on a general register and another

general register or immediate data.

XOR

B/W/L

⊕ Rs → Rd, Rd ⊕ #IMM → Rd

Performs a logical exclusive OR operation on a general register and

another general register or immediate data.

NOT

B/W/L

¬ (Rd)

→ (Rd)

Takes the one's complement of general register contents.
