[1] Assembly-Language Format
MULXS.B/W Rs, Rd
MULXS.B/W #xx:4, Rd
[2] Operation
Rd × Rs → Rd
Rd × #IMM → Rd
[3] Operand Size
Byte, word
[4] Description
This instruction multiplies the source operand by the lower 8 or 16 bits of the contents of the
destination register (Rd) and stores the 16- or 32-bit result in the destination register. The
multiplication is signed. The operation performed on 8-bit operands is 8 bits × 8 bits → 16-bit
product, and the operation performed on 16-bit operands is 16 bits × 16 bits → 32-bit product.
A 4-bit immediate data in the source operand is extended to an 8- or 16-bit unsigned data.
