Hi there,

I have a question relating to microprocessors:

What is a code vector, for example the reset and interrupt vectors? I can't find anything on google or here...can you guide me to some sources please? Is there another name for a "code vector"?

Thanks

 

It's a memory address, or list of memory addresses that the processor branches to on an interrupt or reset.

Here's a Wiki entry on it:
http://en.wikipedia.org/wiki/Interrupt_vector

 

Thx ... another question though: is that not a definition in particular? What is a code vector in general? Also, why is it called a vector?

 

because the memory location holds a 'pointer' to the code itself. As this 'pointer' can be of varying distance (memory range), using the term 'vector' is appropriate.
