[rtl] Flops and timing

[Philip N Daly <pnd@noao.edu>]

Hi all,

Not specifically real time Linux but does anyone know:

1. How long (in ns, us, ms) it takes to execute a floating point
   operation in C and x86 assembler on a 500MHz Pentium III?
   
2. How long the delay is when reading from a PCI card ... i.e. if
   the operation value = readPCI(channel) is atomic, how long would
   it take to execute that instruction (again in ns, us, ms)?
   
Thanks in advance,
