Hello Patricio,

C6500 architecture can be a good starting point:

or

http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps708/prod_white_paper0900aecd80673385.html

the other linecards should use the shared bus when talking to ports of the WS61XX card.

Hope to help

Mixing card types can lead to decreased performance. For instance, 67xx cards are fabric only and 61xx cards (I recall) shared bus only. Believe traffic would need to flow via sup between them. (Giuseppe's references should provide some further details.)
