2.3 Coprocessor
ML62Q1000 series has the built-in multiplier/divider in the coprocessor.
The multiplier/divider is operated using coprocessor data transfer instructions of the CPU. For coprocessor data transfer
instructions, see "nX-U16/100 Core Instruction Manual".
Multiplier/Divider
2.3.1
The multiplier/divider has following arithmetic functions:
Ÿ
Multiplication
: 16 bit x 16 bit (operation time 4 cycles)
Ÿ
Division
: 32 bit/16 bit (operation time 8 cycles)
Ÿ
Division
: 32 bit/32 bit (operation time 16 cycles)
Ÿ
Multiply-accumulate (non-saturating) : 16 bit x 16 bit + 32 bit (operation time 4 cycles)
Ÿ
Multiply-accumulate (saturating)
: 16 bit x 16 bit + 32 bit (operation time 4 cycles)
Ÿ
Signed or unsigned operation setting
Ÿ
In a saturating multiply-accumulate operation, the result is fixed to 0x7FFF_FFFF for a positive number and
0x8000_0000 for a negative number when it is out of the expressible range.
See "User's Manual for Multiplication/Division Library Supporting MULDIVU8LIB Accelerator" for the
multiplication/division library using the multiplier/divider.
