MUL

MUL - unsigned Multiply

Unsigned multiply of the accumulator by the source.

If “src” is a byte value, then AL is used as the other multiplicand and the result is placed in AX.
If “src” is a word value, then AX is multiplied by “src” and DX:AX receives the result.
If “src” is a double word value, then EAX is multiplied by “src” and EDX:EAX receives the result.

The 386+ uses an early out algorithm which makes multiplying any size value in EAX as fast as in the 8 or 16 bit registers.

Usage:

	MUL	src
