Hey all

I've a module on Computer Systems at uni and I'm stuck on a question.

I've got this instruction:

ADD V, 4, 1002

ADD = Add
V = Immediate Addressing Mode
4 = Register 4
1002 = Memory location

Register 4 contains EFFD
Memory location 1002 contains 65C7

Immediate Addressing Mode means: The operand in the actual value specified in the instruction.

I'm asked to describe the effect of this instruction when executed.

I have no idea where to start.

Can someone help me out?

Mike
 
write Chuck Norris as the answer and it is a proven fact that you will always get the question right :P
 
read the book. this is a basic question on memory addressing/accessing, numbers systems and flag bits

what system is this? I have never heard of 'V' being used to imply immediate addressing. Also I don't know the syntax of language thus I don't know which operand is src dst
