| | 3 | = !VciPiTargetWrapper Functional Description = |
| | 4 | |
| | 5 | This hardware component is a VCI/PIBUS protocol converter. |
| | 6 | It behaves as a target on the PIBUS interface, and behaves as an initiator on |
| | 7 | the VCI interface. It can be used by a VCI target to interface |
| | 8 | a PIBUS based system on chip. |
| | 9 | * A single FSM controls the PIBUS and VCI interfaces. Therefore, the throughput |
| | 10 | cannot be larger than 2cycles per 32bits words, even in case of a burst. |
| | 11 | * The supported PIBU response codes are PI_ACK_RDY, PI_ACK_WAT, and PI_ACK_ERR. |
