VciPiTargetWrapper

1) Functional Description

This hardware component is a VCI/PIBUS protocol converter for a VCI target. 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.

As a single FSM controls both the PIBUS and VCI interfaces, the maximum throughput is 2 cycles per 32bits words, even in case of a burst.
