All the
"MAC Management Interface"
core connect directly to the signals of the same name at both the TEMAC and Ethernet
Statistics cores.
The Ethernet AVB Endpoint core provides two separate
Interface"
inputs for management reads. This allows for logic-less connections
between all three cores as illustrated. To achieve this
♦
connect host_rd_data_mac[31:0] of the Ethernet AVB Endpoint core to the
host_rd_data[31:0] port of the TEMAC.
♦
connect host_rd_data_stats[31:0] of the Ethernet AVB Endpoint core to
the host_rd_data[31:0] port of the Ethernet Statistics core.
