ARM - Assembly Language Program

[lyl]

Hi
I've started to learn how to program using the ARM
toolkit, on Windows 2000. Could you please help me?
I need to write a monitor program to implement the
following commands. Input should be in hexadecimal
form.
1) display the contents of the memory word,
2) display the contents of the memory byte,
3) display the contents of the specified register,
4) copy a block of memory from one address to another,
starting at <dest>,
5) change the data representation to either big-endian
or little-endian,
6) change the display of memory/ registers to decimal,
hexadecimal or binary.

Thanks
