BCM1255

DUAL-CORE 64-BIT MIPS^®PROCESSOR (NEW!)

S U M M A R Y O F B E N E F I T S

F E A T U R E S

Two 64-bit MIPS CPUs, scalable from 800 MHz–1.2 GHz

•

Industry-leading performance

•

Quad issue in-order pipeline with dual-execute and dual-memory

pipes

Enhanced skew pipeline enables a zero load-to-use penalty

32-KB instruction cache and 32-KB data cache (ECC protected)

•

2.5 Dhrystone MIPS/MHz per CPU

10 Million packets per second of L3 forwarding

128 Gbps on-chip bus bandwidth, with 100 Gbps memory

bandwidth and 31 Gbps 1/0 bandwidth

•

Fast on-chip multiprocessor bus

•

Low-power dissipation of 13W @ 1 GHz

•

Connects the CPUs, L2 cache, memory controller, and I/O

bridges

High functional integration, reducing overall system cost

•

Runs at half the CPU core frequency and is 256 bits wide

Programming ease and flexibility based on MIPS64™

instruction set architecture (ISA)

On-chip L2 cache

•

512 KB shared by two CPUs and I/O agents

Eight-way associative, ECC protected

Any way can be programmed as fast on-chip RAM

Software compatible with BCM1250 and BCM112x

Broad tools and system software support

•

DDR memory controller

•

Memory bandwidth as high as 100 Gbps

Configurable as 2x64-bit or 4x32-bit wide channels

Runs up to 400-MHz clock rate, 800-MHz data rate

Support for DDR1, DDR2, and FCRAM

A P P L I C A T I O N S

Integrated network and system I/O

•

Four Gigabit-Ethernet MACs configurable as packet FIFO

interfaces

Because of its world-class performance, power efficiency, and

integration, the BCM1255 processor is ideal for a broad variety of

applications, including:

•

64-bit PCI-X interface at 133 MHz

Generic I/O for direct connect to boot ROM, flash memory

Two SMBus serial configuration interfaces

PCMCIA control interface and up to 16 interrupts

Four UART interfaces

•

Enterprise-class routers and switches

Multifunction security platforms (VPN/SSL/IDS)

Compact NAS platforms

SAN routers/gateways/switches

Video servers and systems

On-chip debug capability

•

EJTAG

Bus trace unit (internal logic analyzer)

Support for leading operating systems, including VxWorks ,

•

Linux , QNX , and NetBSD

Evaluation board platform available with samples (includes

tools, firmware, and software drivers)

VPN/Firewall Application

Storage System or Video Server

SATA Disk Drives

DRAM
