Atheros Adds Network Processor and Debuts 802.11n Chipset with 2x2 MIMO

Atheros Communications launched its first family of network processors, the AR7100, targeting triple-play wireless APs and routers. Key features of the Atheros network processors include a high-performance MIPS-based processor core; a 33/66 MHz PCI interface; dual Ethernet ports for LAN and WAN connectivity; a high- speed 32-bit DDR memory controller to support high-bandwidth applications; and on-chip cache memory. The NPUs also offer dual USB 2.0 interfaces for wireless network storage and printing; a PCM interface to support analog and VoIP telephony; and an I(2)S interface to support audio streaming through the router.
