= !VciSimpleRingFast =

== 1) Functional Description ==

This hardware component is a VCI compliant ring, implemented as a combinational daisy-chain and well suited for FPGA implementations. 

Policy arbitration uses a circulating token which allows the wrappers to access the ring in a round-robin fashion.

== 2) Component definition & usage ==
