Hi

What does 'offset' means?? is it related to some addressing scheme??
 

hi,

It depends on what context you are referring to.

One example.. suppose you have two signals and they have fixed delay and you know the arrival time of 1st signal, then the delay can be considered as an offset and can be added to the arrival time of 1st signal to get the arrival time of 2nd signal.
there can be 100s of examples.. but offset is nothing but some known difference ( it may be time , it may be address as well ).
 

I think you are referring to 'offset' in addressing schemes.
While assigning addresses to registers usually there is something called BASE address and there is something else called OFFSET address. The base address is usually assigned to a group of registers eg. FF00 hex. while the offset address of 10 registers in that group will be 1,2,3...A. Th actual address is given by BASE address + offset address.
Note that base address is fixed while offset address keeps changing..
