• Manufacturer Part Number: bcm1111
• Description: Bcm1111 - Voip Cpe Engine
• Manufacturer: Broadcom Corp.

The Broadcom BCM1111 VoIP processor offers a high level of system
integration, performance, and features for Ethernet residential gateway
and stand-alone media terminal adapter applications.
The BCM1111 is a highly-integrated VoIP processor based on a MIPS32
300-MHz enhanced processor core (600-DMIPS). The revolutionary
Voice on MIPS
VoIP applications.
This enhanced processor core utilizes advanced instruction sets, two
single-cycle multiply and accumulate engines, and optimized memory
structures to deliver the highest level of performance on complex
vocoders. Also integrated are dual analog codecs, two 10/100 Ethernet
MACs, one 10/100 PHY, and a 32-bit, 33-MHz PCI/CardBus interface.
