Motorola MC68000

[sniper007]

Hi guys!

I need some help. I'd like to write program which calculate average number of some 16bit signed numbers which is stored in memory.

I don't know how to add 16bit signed numbers ?

can you please help me ?

Do you remember doing sums at school? For example:

19
27+
==

9+7=16, so write 6 and carry the 1. 1+2 is 3, plus the carry is 4. That's basically the algorithm you need to implement.

hi s7,
Look at these links, the first link is to maths subroutines for the PIC.
