| 5 | == 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 : |
| 7 | |
| 8 | * [wiki:Component/VciRingInitiatorWrapper VciRingInitiatorWrapper] : A VCI-RING protocol converter for a VCI initiator. |
| 9 | * [wiki:Component/VciRingTargetWrapper VciRingTargetWrapper] : A VCI-RING protocol converter for a VCI target. |
| 10 | * [wiki:Component/RingGateway RingGateway] : A ring interface with global interconnect. |
