描述 Description

The Broadcom AirForce® BCM4704/BCM4703 wireless networking processors are high-performance, low-power System On a Chip (SoC) devices designed to support all IEEE wireless networking standards.These devices offer features such as simultaneous dual-band operation, an expandable platform and fast time-to-market that differentiate end products. Rich in integrated hardware and software features, the BCM4704/BCM4703's designs are optimized for use in IEEE 802.11a/g access points and routers. The BCM4704/BCM4703 integrate an advanced custom 400 DMIPS/300 MHz MIPS32 core with a V.92 codec interface, two 10/100 Ethernet MACs, 2-way, set associative, 16-KB I-cache and 16-KB D-cache. In addition to all MIPSII instructions, the MIPS core includes extra instructions that optimize the DSP algorithms used for communications, audio and video applications. An integrated MMU, with a 32-entry TLB, provides support of multithreaded operating systems such as the standard distribution Linux. The V.92 data/fax/voice modem interfaces to an external serial modem codec/DAA. It also has two 10/100 Ethernet MACs that are ideal for residential gateways routing information between the WAN port and one or more Ethernet LAN ports.
