MPC8568E Overview
TCP/IP acceleration and QoS features:
— IP v4 and IP v6 header recognition on receive
— IP v4 header checksum verification and generation
— TCP and UDP checksum verification and generation
— Per-packet configurable acceleration
— Recognition of VLAN, stacked (queue in queue) VLAN, 802.2, PPPoE session, MPLS stacks,
and ESP/AH IP-security headers
— Supported in all FIFO modes
— Transmission from up to eight physical queues
— Reception to up to eight physical queues
Full- and half-duplex Ethernet support (1000 Mbps supports only full duplex):
— IEEE 802.3 full-duplex flow control (automatic PAUSE frame generation or
software-programmed PAUSE frame generation and recognition)
IEEE Std 802.1 virtual local area network (VLAN) tags and priority
VLAN insertion and deletion
– Per-frame VLAN control word or default VLAN for each eTSEC
– Extracted VLAN control word passed to software separately
Programmable Ethernet preamble insertion and extraction of up to 7 bytes
MAC address recognition
Ability to force allocation of header information and buffer descriptors into L2 cache
1.2.6
DDR SDRAM Controller
The MPC8568E supports DDR SDRAM and DDR2 SDRAM. The memory interface controls main
memory accesses and provides for a maximum of 16 Gbytes of main memory.
The MPC8568E supports a variety of SDRAM configurations. SDRAM banks can be built using DIMMs
or directly-attached memory devices. Sixteen multiplexed address signals provide for device densities of
64 Mbits, 128 Mbits, 256 Mbits, 512 Mbits, 1 Gbits, 2 Gbits and 4 Gbits. Four chip select signals support
Table 1. Supported eTSEC1 and eTSEC2 Configurations1
1 Both interfaces must use the same voltage (2.5 or 3.3 V).
