Overview
– Up to 16 exact-match MAC addresses supported
– Broadcast address (accept/reject)
– Hash table match on up to 512 multicast addresses
– Promiscuous mode
— Buffer descriptors backward compatible with MPC8260 and MPC860T 10/100 Ethernet
programming models
— RMON statistics support
— 10-Kbyte internal transmit and 2-Kbyte receive FIFOs
— Two MII management interfaces for control and status
— Ability to force allocation of header information and buffer descriptors into L2 cache
10/100 Fast Ethernet controller (FEC) management interface
— 10/100 Mbps full and half-duplex IEEE 802.3 MII for system management
•
•
— Note: When enabled, the FEC occupies eTSEC3 and eTSEC4 parallel interface signals. In such
a mode, eTSEC3 and eTSEC4 are only available through SGMII interfaces.
OCeaN switch fabric
— Full crossbar packet switch
— Reorders packets from a source based on priorities
— Reorders packets to bypass blocked packets
— Implements starvation avoidance algorithms
— Supports packets with payloads of up to 256 bytes
Two integrated DMA controllers
•
— Four DMA channels per controller
— All channels accessible by the local masters
— Extended DMA functions (advanced chaining and striding capability)
— Misaligned transfer capability
— Interrupt on completed segment, link, list, and error
— Supports transfers to or from any local memory or I/O port
— Selectable hardware-enforced coherency (snoop/no snoop)
— Ability to start and flow control up to 4 (both Channel 0 and 1 for each DMA Controller) of the
8 total DMA channels from external 3-pin interface by the remote masters
— The Channel 2 of DMA Controller 2 is only allowed to initiate and start a DMA transfer by the
remote master, because only one of the 3-external pins (DMA2_DREQ[2]) is made available
— Ability to launch DMA from single write transaction
Serial RapidIO interface unit
•
— Supports RapidIO Interconnect Specification, Revision 1.2
— Both 1x and 4x LP-serial link interfaces
— Long- and short-haul electricals with selectable pre-compensation
— Transmission rates of 1.25, 2.5, and 3.125 Gbaud (data rates of 1.0, 2.0, and 2.5 Gbps) per lane
