ARM LINKS ANS DOCUMENTAION OF THE ARCHITECTURE

[[email protected]]

Dear All

I am newbe to the ARM Processor, I dont have any Idea of ARM
processor,
I have to learn about the ARM processor, Please Guide me with the
links
and the documentation where i can find the materials on the arm
processor.

I have to port the floating pont implementaion into the fixed point
implementaion in the ARM processor.

So please Guide me on the above so that I can get the Inhand
knowledge
of the arm processor.

Thanks In Advance.

Well, I don't know what an "ARM processor" is, but if all you have to
do is port floating point into fixed point, just learn how floating
point works, and implement it in integers. It uses shifts and scaling.
Oh, and probably some base conversion. It might even be easier to
do it in BCD (binary-coded decimal).

If your assignment expects you to already know how to program the
ARM processor, then, of course, you'll have to learn how to program
the ARM processor.

But simulating floating point in fixed point isn't difficult - it's
merely tedious.

Here's a possible starting point or two:

Good Luck!

Read and understand the link Martin has sent. ;^)

Pick the core you want to use and read the document:

http://www.arm.com/documentation/ARMProcessor_Cores/index.html

The trick to efficient fixed point math is to know when you
can afford less accuracy than floating point provides. This
is problem dependent and can't be done in a generic way.
A FP emulator is the way to go if you don't understand
the problem.

ARM Ltd. does provide a floating point emulator for their
processors. Two more ARM FP emulators come with the Linux
kernel and another one with ARM-GCC. All open source.

Kind regards,
