Mnemonic
MUL MULTIPLY INTEGERS. Multiplies the two
(3 operands) source integer operands, using signed
arithmetic, and stores the 32-bit result into
the destination long-integer operand. The
sticky bit flag is undefined after the instruction
is executed.

MULB MULTIPLY SHORT-INTEGERS. Multiplies
(2 operands) the source and destination short-integer
operands, using signed arithmetic, and stores
the 16-bit result into the destination integer
operand. The sticky bit flag is undefined after
the instruction is executed.
