Thanks for quick reply ,
Actually we making Bio-Metric devices using Android
Platform. There I've been using a algorithm for matching the templates.
Here i have facing big challenge.
In case of Linux (RedHat, Ubuntu) this algorithm gives
milliseconds to compare 100 templates.
And also in Windows 3 seconds. But in Android it leads 30 seconds. It's
huge different right.
My biggest doubt is Why this huge different even though
using same Linux kernel.
*My Platform Specification:*
*
*
* *1. ARM cortex A8 processor with 750 GHZ.
2. Beagle Bone is the developing kit.
3. That algorithm has fulfill ISO standards.
