I'm looking for some 32-bit integer math routines for a Texas Instruments
TMS320C25 Digital Signal Processor.  Specifically, I need an integer
divide routine what will divide two 32-bit 2's complement integers,
giving a 16-bit integer result.  I only need the quotient -- I don't care
about the remainder.  The programmer's manual for the TI chip gives
good examples for extended precision math for adds, subtracts, and
multiplies, but not divides.  There's a god reason -- the TMS320 chip
doesn't even have a divide operation -- even for 16 bits.  

If anyone has a routine that performs this kind of division, I'd really like
to hear form you.  Even a division that works only with signed magnitude
or positive binary numbers would be fine.  Please mail any replies 
directly to me if possible.  Thanks!
