[Gc] Regarding Data structures

[vasantha selvi]

Hi,
  I tried to get a highlevel picture of the datastructures used for mainting 
memory\heap by the gc.
I refered "Two-Level Trees Structure for Fast Pointer" but still I am able 
to get the clear relationship between pointers and all the datastructure. 
Still I have big question on how the heap is split into
different sized blocks and how it mapping is done.
Please any could help me out with some more references docs or can u urself 
give some brief explanation of the total data structure.
Awaiting for ue valuable responses,
Regards,
VS
