FEATURES
The RM9222 RM9000x2GL Integrated Multiprocessor builds on the success of PMC-Sierra's next generation MIPS-based? RM9000 Family processors by providing features specifically suited for network processing applications. It provides:
?Dual CPU cores compatible with the MIPS64? Instruction Set Architecture. ?High-speed integrated DDR SDRAM, Local Bus, PCI, Ethernet MAC interfaces. Option to bypass the Ethernet MAC interface to provide a high-speed Generic Packet Interface.
DUAL 1 GHZ PROCESSORS
Each processor features:
?A dual issue superscalar 7-stage pipeline.
?16-Kbyte, 4-way set associative L1 Instruction and Data caches.
?256 Kbyte, 4-way set associative L2 cache with deterministic access time for highest performance.
?Fast Packet Cache? to assist packet data processing.
?An 8K entry branch prediction table.?Fully associative 64-entry TLB with dual pages.
?Multiple reads with out-of-order return. ?High-performance Floating Point Unit (IEEE 754).
?Fixed-point DSP instructions.
CACHE AND I/O COHERENCY
?Maintains hardware cache coherency with the 5-State MOESI protocol. All cache transfers between processors occur at the CPU pipeline frequency. ?Supports full hardware I/O coherency over the PCI and Ethernet MAC/GPI networking interfaces allowing I/O devices access to coherent memory.?Provides Direct Deposit Cache mode allowing the DMA of packet headers directly into L2 cache from PCI, Ethernet MAC, and Generic Packet interfaces.
160 Gbps MULTI-PORT PACKET SWITCH
?Connects processors to memory and I/O interfaces.
?Supports simultaneous transfers on all ports.
200 MHZ MEMORY CONTROLLER
?Supports 25.6 Gbps memory.?Supports DDR SDRAM options.?Supports 2 Gbytes using 512 Mbit SDRAM and 4 Gbytes using 1 Gbit SDRAM.
NETWORKING INTERFACES
?Provides a 32-bit 33/66 MHz PCI interface compliant with the PCI 2.1 standard.
?Provides 2 Ethernet MAC or Generic Packet Interfaces:
?Ethernet MAC interfaces support standards-based TBI (1000 Mbps), GMII (1000 Mbps) and MII (10/100 Mbps) interface modes.
?Generic Packet Interface supports 8-bit and 16-bit operation at 104 MHz using LVTTL I/O levels or at 208 MHz using HSTL I/O levels.?Dedicated multi-channel DMA for Ethernet MAC/GPI interfaces
?Provides a 33 MHz Local Bus interface for connectivity to boot-up and control devices.
ADDITIONAL FEATURES
?Provides 8 Kbytes integrated low latency scratch RAM.
?Provides an integrated on-chip EJTAG Debug module to ensure easy
debugging of hardware and software and a Trace Buffer to allow tracing instruction execution for debugging.?Provides a flexible 4-channel DMA control architecture providing DMA to any block, scatter/gather support, and external DMA request support.?Provides a vectored, prioritized interrupt controller that supports:?256 prioritized interrupts.
?Programmable interrupt delivery modes, for inter-processor as well as external and PCI interrupts.
