1. Project: Samsung Femto cell for Home/Small Office
Company: Samsung Research India Bangalore (SRIB).
Duration: March 2015 till date
Platform: Broadcom BCM61735, Linux.
Femtocell/Small cell is a very small mobile phone base station which is connected to the phone net-
work via the Internet, typically used in areas where the mobile signal is weak. We are currently work-
ing on Broadcom chipset BCM61735 for femto Product.

6. Project: Task Stack Protection Code Design and Implementation
Company: Samsung Research India Bangalore (SRIB)
Platform: C, REX, Nucleus.
March 2009 -DEC 2009
We successfully Implemented stack protection Using Memory Management Unit (MMU) in ARM9
modem processors. While Debugging crashes in Samsung Mobile Phones there were lot of Crashes
reported because of one task’s stack area Being corrupted by some other task ,so to avoid stack
Corruption and to catch the culprit task which is corrupting the other task’s stack we implemented
stack protection which the Help of Memory management Unit. Here the idea was to limit a task to
write some other task’s stack area .when a task tries to write to some other task’s stack the system
would generate an Abort. We could easily find out the Task which was corrupting the other task’s
stack areas.
Responsibilities:
 Arranging all Task’s stack areas to continuo's memory Blocks.
 Changing Access Permission Bits in Page Table entries of ARM MMU.
 Coding to protect task’s stack regions.
 Used this stack protection design to debug Memory corruption issues.

4. 7. Project: Development of RAM Dump Analyzer Tool
Company: Samsung Research India Bangalore (SRIB)
Platform: C, REX, Nucleus, Microsoft Visual studio.
NOV 2008 -March 2009
There a was need for a tool which quickly analyses the Crashes that occur in Samsung Mobile phones
so we Developed a tool called Ram dump Analyzer (RDA).RDA is a Automatic Crash Analysis tool
which will analyze the System Crashes without ELF within few minutes and generates a HTML Report
giving the Problem point, From the report generated the developer could easily find out the Root
cause of the Crash and Hence he could fix the issue with Ease.
Responsibilities:
 Design, coding & testing of RDA (RAM Dump Analyzer) Tool.
 CMM file Writing and Symbol Table Extraction code writing for Call Stack.
 Designed and Developed HTML creation API’s for displaying generated analysis reports
Achievements
“Beyond Boundaries” Award for My contribution in developing a Debugging tool for Samsung
Mobile Platform.
“Business contribution award for Samsung droid phone”
“Perfectionist award for contribution towards Samsung Wave phones.
