Is there in relation to Big/Little endian mode any performance penalties =
on a ARM920T core?
I noticed that on some of the Intel XScale processors only Big endian =
mode is allowed, so I figure the dual compatible endian mode processors =
has to do some conversion internally in one of the modes not native to =
the execution unit.
