    55== 1) Functional Description ==
    6 This hardware component is a VCI compliant ring, implemented as a combinational daisy-chain and well suited for FPGA implementations. It must only be used in clusterized architecture, to interconnect a limited number of VCI initiators and targets in a local sub-system. It contains two independant rings for VCI commands and VCI responses and is composed of three components :

     12Policy arbitration uses a circulating token which allows the wrappers to access the ring in a round-robin fashion.
