The SiByte Broadband Processors form a family of high performance system-on-a-chip parts targeted at
network centric tasks. Examples include:
• In-line packet processing
• Exception processing
• Switch control and management
• Higher layer switching and filtering
• Protocol conversion (VoIP Gateway)
• Network appliances (file servers, web cache, print servers)
• VPN access, firewalls, gateways
The different members of the family target different performance points and applications, while retaining
software compatibility. This User Manual covers the dual-processor BCM1250, and the uni-processor
BCM1125 and BCM1125H parts.
All the parts use the SB-1 CPU core. This is a high performance implementation of the standard MIPS64
instruction set architecture. The core supports a 4-issue enhanced skew pipeline and can dispatch up to two
memory and two ALU (Integer, Floating point or MIPS-3D) instructions per cycle.
