==Linpack==
 
 
 
The Arm has been tested using the linpack benchmark from [http://www.netlib.org/benchmark/linpackc.new], built with gcc with -O3 (Optimisation level 3). Run with array size 200.
 
 
 
With software floating point

Rebuilding the Whetstone test code with 'gcc -mfpu -float-abi=softfp' gives better results:
 
<pre>
 
 
 
Loops: 1000, Iterations: 100, Duration: 106 sec.
 
C Converted Double Precision Whetstones: 94.3 MIPS
 
</pre>
 
 
 
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.
