Did you use the same cc opts as me?
( OPTON = -O3 -pipe -fomit-frame-pointer -finline-functions)
It seems quite amazing that some of the tests on the SA110 are almost
half the speed, and how can the Dc: sqrt(2) to 99 decimal places be
2.5 times quicker on the Arm7? I would have assumed this to be a purely
computational thing (Like Dhrystone and Arithmetic test) and so be
quicker on the SA
Also, I don't believe my results for FileRead. I'm running on the
internal 420Mb IDE and 65MB per sec seems a bit much! Dunno why this
should produce such weird results!
Here's a side by side comparison of the two systems.
