Multiplying 32-Bit Binary Data - Mitsubishi MELSEC iQ-F FX5 series Programming Manual

Multiplying 32-bit binary data

D*(P)(_U) instruction and DMUL(P)(_U) instruction can be used for multiplication of 32-bit binary data.
D*(P)(_U)
These instructions multiply the 32-bit binary data in the device specified by (s1) and the 32-bit binary data in the device
specified by (s2), and store the result in the device specified by (d).

Operand Description
(s1) D*(P) Multiplicand data or the head device where the
data to be multiplied by another is stored
D*(P)_U

Processing details
• These instructions multiply the 32-bit binary data in the device specified by (s1) by the 32-bit binary data in the device
specified by (s2), and store the multiplication result in the device specified by (d).

• When (d) is a bit device, only the lower 32 bits of the multiplication result are stored and the upper 32 bits cannot be
specified. If the upper 32 bits data of the multiplication operation result are required, temporarily store the result in a word
device, and transfer the data stored in word device ((d)+2) and ((d)+3) to the specified bit devices.
Ex.
Multiplication result when (d) is a bit device
• K1 ... Lower 4 bits (b0 to b3)
• K4 ... Lower 16 bits (b0 to b15)
• K8 ... Lower 32 bits (b0 to b31)
