VciPiTargetWrapper Functional Description

This hardware component is a VCI/PIBUS protocol converter. It behaves as a target on the PIBUS interface, and behaves as an initiator on the VCI interface. It can be used by a VCI target to interface a PIBUS based system on chip.

• A single FSM controls the PIBUS and VCI interfaces. Therefore, the throughput

cannot be larger than 2cycles per 32bits words, even in case of a burst.

• The supported PIBU response codes are PI_ACK_RDY, PI_ACK_WAT, and PI_ACK_ERR.
