AMD is shipping a development board for the Alchemy Au1550 network security processor. The DBAu1550 board targets developers of low-powered network access devices with integrated security, such as gateways, network attached storage (NAS) units, wireless access points, and voice over Internet protocol (VoIP) devices.

The Au1550 chip

The Au1550 processor is the newest in AMD's Alchemy embedded processor line. The MIPS-based system-on-chip (SoC) draws only half a watt, and features configurable security features licensed as intellectual property from SafeNet. AMD says that SafeNet's CGX Mobile Library enables processor customers to design security solutions with multiple price-performance options, using the same software application-programming interface (API).

Advanced security features in the Au1550 include implementations of "the entire VPN packet protocol" in hardware, support for both IPsec and SSL VPNs, the capability of sustaining "unlimited VPN tunnels sumultaneously," and a True Random Number Generator (RNG). Low power requirements enable the processor to support battery and Power Over Ethernet (PoE) applications.
