Reverse the number

  1. Mar 23, 2006 #1
    Can some one guide me ,,how to write an assembly language function for Pentium-class PCs with the following features.

    1. C callable.
    2. Takes one 32-bit argument
    3. Returns 32-bit argument obtained by reversing the bits of the input (i.e. bit 0 of input appears at bit 31, bit 1 at bit 30 and so on).
    4. Write another function in C which implements the same behavior.
    5. Using the time related function calls, find the time of execution of C function and assembly language function (when the call is made 50000 times).

    i just need an general outline..I will be highly thankful for yours help..
