Functional Block Description
The following functional blocks described in the following sections are illustrated in
Figure 5-1
PLB Interface
The core provides a PLB version 4.6 interface as its configuration port to provide easy
integration with the Xilinx Embedded Development Kit and access to an embedded
processor (MicroBlaze™ or PowerPC®), which is required to run the
All the configuration and status register address space of the Ethernet AVB Endpoint core
can be accessed through the PLB.
Additionally, when the core is generated in
logic provides a logic shim which is connected to the Host I/F of the supported Xilinx Tri-
Mode MAC core; this enables all configuration and status registers of the MAC to also be
available via the PLB. See
AV Traffic Interface
The AV traffic interface provides a dedicated full duplex port for the high priority AV data.
