Cortex-A15MP Core Registers

Hi,

I am using ARM v7-A (Cortex A15 MP) and i want to observe the stack context, as i understand it, there are some offset values inside of ARM Core Registers (between LP, SP and PC), and the offset values are different from program to program (task to task). My main purpose is find the PC, LP adresses by using SP address for each program (task/process).

How can i find these offset values?

Is there any struct about stacks and stack variables?
