Linpack
The Arm has been tested using the linpack benchmark from, built with gcc with -O3 (Optimisation level 3). Run with array size 200.

With software floating point

Memory required: 315K.

LINPACK benchmark, Double precision. Machine precision: 15 digits. Array size 200 X 200. Average rolled and unrolled performance:

Whetstone/Dhrystone
Code for these tests can be found here http://www.rowley.co.uk/arm/whet_dhry.zip.

All code compiled with gcc options -float-abi=softfp -O3

Whetstone

Loops: 1000, Iterations: 10, Duration: 24 sec.

C Converted Double Precision Whetstones: 41.7 MIPS

Dhrystone

Microseconds for one run through Dhrystone: 1.2

Dhrystones per Second: 809061.5

Rebuilding the Whetstone test code with 'gcc -mfpu -float-abi=softfp' gives better results:

Loops: 1000, Iterations: 100, Duration: 106 sec. C Converted Double Precision Whetstones: 94.3 MIPS

However, the majority of compute time is spent in the SQRT function, which for the above test was built without -mfpu=vfp. Using a library with vfp give the following much improved result :

Loops: 1000, Iterations: 100, Duration: 15 sec. C Converted Double Precision Whetstones: 666.7 MIPS
