A driver is fundamentally a piece of software written for a specific device.
Its main tasks are to perform I/O's on a device. To do this there are typically well defined models for a driver.
Generic description of a driver structure will be:
a) Device I/O Address (Physical Hardware -> Logical OS based address)
b) Interrupt that the device generates and its handler (the driver)
c) A software Handler to manage the read write operations to and fro from the device.
WinCE supports both Hard real time as well as soft real time
environment depends on what processor we are using and with
Using Platform builder tool one can make this WinCE OS as
customise O S to his hardware. Which is one of good
advantage over other OS.
We can make as compact as possible O S image just by adding
required component (along with sample code) only in
customize OS Designing.
Windows CE (also known officially as Windows Embedded
Compact post version 6.0, and sometimes abbreviated
WinCE) is Microsoft's operating system for minimalistic
computers and embedded systems. Windows CE is a distinctly
different operating system and kernel, rather than a
trimmed-down version of desktop Windows. It is not to be
confused with Windows XP Embedded which is NT-based
MSFT standard SDK's are,
1. Windows Mobile for Smartphone = Windows Mobile Standard.
2. Windows Mobile for Pocket PC = Windows Mobile Classic.
3. Windows Mobile for Pocket PC Phone Edition = Windows
There are four levels in Win CE architecture.
speciality in the sense ...
1) number of processes supported by wince 5.0 is more
than wince 4.0
2) memory mapping might be varying.
I am not sure in every cases, whether this is true..??
May be the reason is,
While compared to PocketPc, smartphone has a limited h/w
resources, like memories etc. In order to reduce the
kernel+application size, they are removing the libraries for
the MFC .
1) Supports various types of processor platforms
2) Possible to Customize the Kernel and can reduce its size
(upto ~300KB kernel size)
3) Especially for the embedded device platforms
1) Process limits, max. 32 process at a time in WinCE 5.0
2) Limited space allocation for each processes, 32MB/each
