+, FADD
Addition
Equation: V1 = V2 + V3
V1 = FADD(V2, V3) (Signed DW)
Perform the addition on V2 and V3, and store the addition result in V1.
Example:
The value contained within the internal memory address #2 plus 1
$2 = $2 + 1
The values contained within the internal memory address #1 and #2 are combined and the total is
stored in the address #3.
$3 = $2 + $1
The value contained within the internal memory address #4 plus 1.9
$4 = FADD($4, 1.9) (Signed DW)
The floating point values contained within the internal memory address #4 and #6 are combined and
the total is stored in the address #8.
$8 = FADD($4, $6) (Signed DW)
-, FSUB
Subtraction
Equation: V1 = V2 - V3
V1 = FSUB(V2, V3) (Signed DW)
Perform the subtraction of V2 and V3, and store the subtraction result in V1.
