The raw data is for a single Motorola MPC860 (a PowerPC with embedded
peripherals) at 40MHz, believed to be running with no wait states and no
non-clock events under OS-9000. The benchmark was ported to an N of 10,000
to fit into the embedded system's small memory. The port may help
characterize CPU cores of embedded systems.
-------------------------------------------------------------
This system uses 8 bytes per DOUBLE PRECISION word.
-------------------------------------------------------------
Array size = 10000, Offset = 0
Total memory required = 0.2 MB.
Each test is run 10 times, but only
the *best* time for each is used.
-------------------------------------------------------------
Your clock granularity/precision appears to be 29999 microseconds.
Each test below will take on the order of 5739999 microseconds.
(= 191 clock ticks)
Increase the size of the arrays if this shows that
you are not getting at least 20 clock ticks per test.
-------------------------------------------------------------
WARNING -- The above is only a rough guideline.
For best results, please be sure you know the
precision of your system timer.
