Floating Point Division in MIPS assembly

Write a MIPS assembly program to do 32-bit FP division by repeated multiplication. Test for all error condition. Result must be IEEE compliant.

The division function should be written as a callable function using C protocol for activation records on the stack.

SPIM or XSPIM simulator will be used. A tutorial of XSPIM can be found in the CD of the textbook.

A tutorial of PCSPIM can be found at http://ouray.cudenver.edu/~dl0hoshi/4591/spimtutorial.html
