Introduction

The CENTAUR KS8695P, Multi-Port PCI Gateway Solution, delivers a new level of networking integration, performance, and overall BOM cost savings, enabling original equipment manufacturers (OEMs) to provide customers with feature-rich, low-cost solutions for the residential gateway and small office environment.

• Integration of a PCI arbiter supporting three external masters.
  • Allows incorporation of a variety of productivity enhancing system interfaces, including the expanding 802.11 a/g/b wireless LAN.
• High-performance ARM CPU (ARM9) with 8KB I-cache, 8KB D-cache, and a memory management unit (MMU) for Linux and WinCE support.
• XceleRouter technology to accelerate packet processing.
• Proven wire-speed switching technology that includes 802.1Q tag-based VLAN and quality of service (QoS) support.
• Five patented mixed-signal, low-powered Fast Ethernet transceivers with corresponding media access control (MAC) units.
• Advanced memory interface with programmable 8/16/32-bit data and 22-bit address bus with up to 64MB of total memory space for Flash, ROM, SRAM, SDRAM, and external peripherals.
