I'll try again without html attachments. These numbers are for 
CrossWorks 1.3 which uses version 3.4.1 of cc1.exe and cc1plus.exe from 
the GNU Compiler Collection. We use our own C library with the go-faster 
floating point code from gcclib.

Dhrystone v2.1
 
ARM - Code size 9,498 bytes, 51,948 dhry/sec
THUMB - Code size 8,228 bytes, 48,192 dhry/sec

Whetstone

ARM - Code size 12,908 bytes, 2.4 MIPS
THUMB - Code size 10,608 bytes, 2.2 MIPS

All benchmarks were executed on a Philips LPC2294 running at 60Mhz with 
the MAM enabled.

We use debug_stdio.h rather than stdio.h to keep the code size down. 
Which could be considered to be cheating, but demonstrates that end 
applications can do printf style debugging without a big code size increase.

Michael, it's neither here or there, but how come you have two last names :-) ?

If I post from my regular email account then I'm Michael Johnson, if I
post using the yahoo thing (as I'm doing now) then I'm called
nutleycottage for reasons I can't remember.

My mistake, Paul keeps saying Michael, and "Michael Anburaj" also made some 
posts on the GNU benchmarks and I thought you two are one and the same. My 
apology.

Hi Michael

I think the GCC compiler setting KEIL compare is without optimizing.

What was the settings in your  Optimization Level in CrossWorks ?

Could you please mail me the two program source code 
Dhrystone v2.1 adn Whetstone to (john_2005@... )?

best regards

John
