One of the main issues that occurs when trying to run applications from=20=

8xx to 82xx is dealing with the difference in cache line size.  If code=20=

is written properly this difference will be invisible to the user.  It=20=

might be that 8xx code is not as optimal on 82xx because of it.

Also since you are going from 8xx -> 82xx your applications most likely=20=

are all integer code.  Going from 82xx -> 8xx may not be as successful.
