Yes, but the ram requirements are the killer. Dhrystone needs >4K, not
going to fit .....

Hi,
the sources of Dhrystone have only 35 kB size and the sources of
Wheatstone have only 4 kB. They have been used even on the C64.
I´ve got working msp430 projects with up to 470 kB sources (with few
comments).

Rolf

Hi,
i´ve been looking for benchmarks for many platforms and C compilers
and found Dhrystone and Whetstone on www.cs.rit.edu with the source
files and makefiles. I´ve got copies on my server at
http://random.linux-site.net/files/unsorted/benchmarks/.
It should be easy to port them to MSP430 but i didn´t had enough
time to do it.

Do you think those benchmarks have much relevance to a small embedded
processor? I rather doubt it. Unless they are broken up, I think they
are probably much too big to compile for the MSP430 anyway.

Hi,
microcontroller project). Because I did not find any benchmark
results in
the
archive I would like to ask if someone on this list could give me
some
numbers. I am especially interested in the duration for the +-*/
operations
In mspgcc the general rule is integer fast, floating slow. The code
generation is good, but the floating point support library is not that
efficient. There hasn't been enough interest to drive people to
optimise
it. It does full IEEE754 floating point, which drags its speed down
quite a lot. A somewhat stripped down library would be faster, and the
lack of 100% IEEE754 compliance is irrelevant for most embedded users.
I did a very elementary comparison of floating performance with
different MSP430 C compilers a few weeks ago. The results should be
somewhere in the archive for this list. The IAR non-IEEE754 floating
point was a lot faster than the others. Their IEEE754 library was
about
half the speed of the IEEE754 one.
Regards,
Steve
