## Linpack

The Arm has been tested using the linpack benchmark from [1], 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: Reps Time(s) DGEFA DGESL OVERHEAD KFLOPS 2 0.53 92.45% 1.89% 5.66% 5493.333 4 1.07 92.52% 2.80% 4.67% 5385.621 8 2.12 92.45% 2.36% 5.19% 5466.003 16 4.24 92.45% 2.83% 4.72% 5438.944 32 8.49 92.11% 2.71% 5.18% 5459.213 64 16.98 92.05% 2.89% 5.06% 5452.440

## 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
