•
Two 64-bit DDR2/DDR3 memory controllers
— Programmable timing supporting DDR2 and DDR3 SDRAM
— 64-bit data interface per controller
— Four banks of memory supported, each up to 4 Gbytes, for a maximum of 16 Gbytes per
controller
— DRAM chip configurations from 64 Mbits to 4 Gbits with x8/x16 data ports
— Full ECC support
— Page mode support
– Up to 32 simultaneous open pages for DDR2 or DDR3
— Contiguous or discontiguous memory mapping
— Cache line, page, bank, and super-bank interleaving between memory controllers
— Read-modify-write support for RapidIO atomic increment, decrement, set, and clear
transactions
— Sleep mode support for self-refresh SDRAM
— On-die termination support when using DDR2 or DDR3
— Supports auto refreshing
— On-the-fly power management using CKE signal
— Registered DIMM support
— Fast memory access through JTAG port
— 1.8-V SSTL_1.8 compatible I/O
— Support 1.5-V operation for DDR3. The detail is TBD pending on official release of
appropriate industry specifications.
— Support for battery-backed main memory
•
Programmable interrupt controller (PIC)
— Programming model is compliant with the OpenPIC architecture.
— Supports 16 programmable interrupt and processor task priority levels
— Supports 12 discrete external interrupts
— Supports 4 message interrupts per processor with 32-bit messages
— Supports connection of an external interrupt controller such as the 8259 programmable
interrupt controller
— Four global high resolution timers/counters per processor that can generate interrupts
— Supports a variety of other internal interrupt sources
— Supports fully nested interrupt delivery
— Interrupts can be routed to external pin for external processing.
