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. On Friday, October 19, 2012 11:54:53 AM UTC+5:30, Avtar Singh wrote: > > > I know Android uses the Linux kernel.
