[Q]: Dhyrstone & Whetstone

Hi all,

I am working on WinCE 4.2.
What are Dhrystone and whetstone ?
I came across one link in msdn which had some information in this regards,
thats says:
Dhrystone is a suite of arithmetic and string manipulating programs. Since
the whole program is less then 8 kBytes, it fits into the processor cache.
It can be used to measure two aspects both the processor's speed as well as
the optimizing capabilities of the compiler. The resulting number is the
number of executions of the program suite per second.

Can anyone put more light on this along with 'whetstone'.

regards

Dhrystone is the CPU speed measurement suite for integer operations.
Whetstone is the same suite for floating point.

Not the sort of thing you would normally worry about on embedded devices.

See http://ebenchmarks.com/download/ECLDhrystoneWhitePaper.pdf

SiSoft Sandra can compute some perfomance numbers for your WinCE Device if
it is connected via ActiveSync - if you need the confirmation that your
embedded device has much less processing power than your PC ;-)
