What is "image"

The term "image" is most often used for identical memory locations, which can be accessed at different addresses. That happens when addresses are incompletely decoded. A very simple example: an 8-bit CPU might have a total address space of 64kB, i.e. it has 16 address lines (A0..A15). You reserve the upper half for some peripheral registers by selecting these registers if A15 is high. If you use the lower four bits (A0..A3) to select one out of 16 registers, then you can address the first of these registers with any address from 0x8??0...0xf??0. The question mark means that any combination is valid. In other words, an access to 0x8000 adresses the same data as 0x8010. 0x8010 is called an image of 0x8000.

"Image" refers to the "panache", the "charisma", the "joi de vive" that exudes from electrical engineers in the workplace and at social gatherings. Its what draws supermodels of both sexes to cluster around EEs, an attractive life-force that causes high and low society to look past the horned rimmed glasses held together with lint-laden Scotch tape, past the stained plastic pocket protector jammed with cheap Bic pens, past the tattered polyster trousers hitched up over the belly-button.

"Image" is the EE's radiance of creative "schizzle" and its what makes EEs the envy and awe of other professionals.

"Image" may also refer to executable code that runs on a processor. This code may include both the operating system (OS) and a specific task or group of tasks, perhaps programmed by you, Mr. Wong.

HAHAH! thanks for that. seriously.
