What is "image"

W

Wong

Hi,
I often heard that "image" is used in embedded application. This is
something to do with a pointer and it is common to use "image" to
configure the Integrated Circuit (IC).
What is this "image" actually ? Thanks in advance.

Usually it refers to the actual layout of memory of some memory device
(FLash/EEPROM/ROM, etc). This is the ultimate target for crosscompilers for
embedded systems.

The only connection with 'pointer' i can come up with is that the image has
to be loaded at a *very* specific place, since it usually contains *all*
object-code (including the CPU's entry point). In this sense it configures
some IC (The MPU and associated memory).

What made you think this has even the slightest bit to do with C?

For a better discussion try:
What do you mean by "the Integrated Circuit"?
Integrated Circuits range from AND gates to ASICs.

But, I'm getting off-topic.
