3.1.4 smpy16
Subroutine “smpy16” multiplies two 16-bit signed numbers producing a
32-bit signed product. On entry the H:X register points to a 4-byte data
array holding the multiplier and multiplicand. Subroutine “smpy16”
checks for the signs of multiplier and multiplicand and after converting
into positive numbers, calls subroutine “mpy16” which does the
multiplication before the products sign is corrected. The product
overwrites the multiplier and multiplicand. This routine is used to
calculate the instantaneous power from the voltage and current samples
obtained by the A/D converter and also to calculate the mean square
value of the current for range switching.
Figures 3-4
and
3-5
show the
smpy16 and mpy16 flow diagrams.
