Cheng,
 
A couple of notes first:
-you don't specify if you mean PLB v3.4 or PLB v4.6
http://www.xilinx.com/support/answers/29567.htm (9.2i EDK - Legacy OPB/PLBv34 core support plan)
EDK 9.2i introduced the PLB v4.6 bus interface for our embedded processing solutions.
 
-you generally shouldn't cross post into each forum. IP -> Embedded Processing (or perhaps possibly also EDK and Platform Studio) is the right place for this question.
Many users use the "Most recent threads" feature and will see your post(s).
 
I'm not the PLB expert, but ran across this discussion before that you may find useful:
 
I hope this helps.
 
Cheers,
bt

I'm afraid not.
This forum is an excellent vehicle for communicating between users with issues, questions, suggestions, etc.
It can even be a good place for simple examples, e.g. how do I write an 8-bit counter.
 
The resource I suggested above was the best place I know to get started with your question. The PLB specification itself is over 100 pages. This forum is not really a substitiute for a detailed reading of the applicable specification and design of your specific architectural requirements.
 
Maybe someone can offer a better example.
 
If not, you may find these useful:
