Provides a fully integrated device that integrates the
microprocessor and peripherals functions of a cable
modem into a single device complementing the
BCM3300 DOCSIS-compliant PHY/MAC integrated
circuit by:
Reducing overall system cost
Simplifying system, board and software design
Reducing power consumption
Built-in seamless interface with the BCM3300
eliminating discrete interface components from the
system design
80 MHz (85 DMIPS) R3000 CPU with 4K 2-way set
associative I-cache and 1K 2-way set associative
writeback D-cache
Full IPv6 IP Security (IPSec) module to support
advanced applications such as Virtual Private
Networking (VPN)
Fully USB 1.0 compliant interface for simple plug and
play external cable modem implementations
PCI NDIS 5.0 miniport driver to accelerate software
development
