OPB to PLBV46 Bridge

Product Specification
Introduction
The On-Chip Peripheral Bus (OPB) to Processor Local
Bus (PLB v4.6) Bridge module translates OPB
transactions into PLBV46 transactions. It functions as a
slave on the OPB side and a master on the PLBV46 side.
The OPB to PLBV46 Bridge is necessary in systems
where an OPB master device, such as a DMA engine or
an OPB based coprocessor, requires access to high
performance system resources on the PLBv46 bus.
The Xilinx® OPB to PLBV46 Bridge design allows
customers to tailor the bridge to suit their application
by setting certain parameters to enable and disable
features. The parameterizable features of the design are
discussed in Design Parameters.
Features
The Xilinx OPB to PLBV46 Bridge is a soft IP core with
the following features:
• Bridge Functions
- Uses 16-word deep posted write buffer to
decouple OPB and PLBV46 transactions.
- Uses 16-word deep read prefetch buffer to
eliminate bridge related system lockup issues.
• PLBV46 Master interface
- 32-bit native device width
- Communicates with 32-bit, 64-bit, and 128-bit
PLBV46 slaves
- Non-burst transfers of 1 to 4 bytes
- Uses fixed length, burst signaling of up to 16,
32-bit words.
