Where do we start?We need to understand systems level software and how Windows CE fits in.

Where do we start?We need to understand systems level software and how Windows CE fits in. “Systems” has to do with the software that is in between the user programs and computer hardware.

What does Windows CE do for me?A Windows CE Operating system “Image” is a collection of systems software.

What does Windows CE do for me?A Windows CE Operating system “Image” is a collection of systems software.Microsoft includes in Windows CE 6.0 a choice of four possible CPU “architectures” that can be used to base your computer hardware on.

What does Windows CE do for me?A Windows CE Operating system “Image” is a collection of systems software.Microsoft includes in Windows CE 6.0 a choice of four possible CPU “architectures” that can be used to base your computer hardware on.An architecture is the structure behind a way of computing ‐ adding, subtracting and multiplying bits, and loading them from or storing them to memory.

The choice of an architecture is the starting point for the design of a computer system.

An architecture isn’t a physical thing. It’s a specification of how a CPU core should work.

An architecture isn’t a physical thing. It’s a specification of how a CPU core should work.An actual implementation of an architecture version ends up as a particular CPU core.

The choice of an CPU core (and therefore an architecture) is typically the second thing you do in defining a computer.

The choice of an CPU core (and therefore an architecture) is typically the second thing you do in defining a computer.
A CPU core is typically built in to a ‘SoC’ or System‐On‐Chip. This is a combination of a CPU Core and some support logic and peripherals highly tuned to work with that core.
