MEMORY MAPS AND POOL CONFIGURATION

The BCM5722 Ethernet controller provides internal SRAM memory for Ring buffers, Tx Packet Mbuf memory, Rx Packet

Mbuf Memory, Misc shared memory, and Status block. The memory maps show how the internal SRAM is mapped into the

address space from the:

• On-chip RISC CPU view

• Host standard view

• Host indirect (UNDI) view

• Host flat views
