BCM1111
BCM1111 Block Diagram
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
®
technology eliminates the need for a separate DSP for
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.
DMA
Control
For a four-port LAN, two-port voice terminal adapter router, the
BCM1111, along with the BCM5325E, enables a two-chip solution.
For a Wireless LAN, four-port LAN, two-port voice terminal adapter
router, the BCM1111, along with the BCM4318E and BCM5325E,
enables a three-chip solution.
BCM91111 SMTA Reference Design
To accelerate the product development cycle and time to market, the
BCM1111 comes complete with a reference design that includes
schematics, layout, BOM, and VoIP and 802.11 networking software.
