Introduction This document provides the design specification for the OPB to OPB Lite Bridge. The OPB to OPB Lite Bridge is used to connect two OPB buses. The bridge has one master port and one slave port. Two bridges may be used together to support full bus mastership in both directions. Features •Provides a bridge between two OPB V2.0 buses •Connections for one master-side bus and one slave-side bus •Parameterized data bus widths •Simple transaction forwarding reduces LUT count •Requires the two OPB buses to be on the same clock and the same size •No support for data buffering or posted writes Functional Description The top level block diagram for the OPB to OPB Bridge Lite is shown in Figure 1. A transaction is initiated to the slave side of the bridge. The slave-side signals are registered in the slave attachment and the control state machine begins a request on the master side of the bridge. After the bus has been granted to the bridge, the master attachment begins a transaction on the master side, passing through the signals that were registered in the slave attachment. The transfer acknowledge signals, MOPB_xferAck, MOPB_errAck, MOPB_timeout, and MOPB entry, are passed back through the bridge to the slave side to complete the transaction. A time-out on the master side (MOPB_timeout asserted) is translated to an error acknowledge on the slave side (Sl_errAck asserted). No buffering for burst optimization is performed.
