GENERAL NOTES:
-Displayed CPU speed may be wrong with some custom CPU. Exec returns my 1.4Ghz G4 to run 400Mhz.

MIPS NOTES:
-Benchmarking MIPS is NEVER relevant. From a benchmark to another, the loop used is not the same, giving different results.
-Benchmarking MIPS is in most case optimised for a particular CPU, and irrelevant for a CPU with a different architecture.
-The real "maximum MIPS" capability of a CPU can be known just with its datasheet, without any benchmark. It's "CPU Frequency * Instruction dispatcher outs".
-This is the value I try to bench.

IU32 vs FPU64 NOTES:
-Since v0.37, benchmarks are done two times. Integer 32 and Floating point 64.
-Depending of the benchmak done (L1, L2, Memory...), of CPU architecture, of bus bandwidth, sometime IU32 is faster, sometime it's FPU64.

AONE NOTES:
-Some people use SetA1. Superb tool, thanks to its author!
-ECC ram are a bit slower.



HISTORY

v0.37
-Added a small MIPS benchmark.
-Now bench with IU32 and FPU64 instead of only FPU64.
-Maybe the "Slow L1" problem on Sam440 is solved.

v0.36
-Tryed something different for the video bus speed, results may differ a bit from older versions.
-The way I use to read/write video memory is very crap, but at least it should work this time.
(I hope so)
(really...)
(sigh)

v0.35
-DO NOT USE ANYMORE THIS PRIVATE VERSION, RESULTS ARE WRONG!

v0.34
-First release
