AT2-5800刀片开发板
The AT2-5800, based on two high performance OCTEON™ Plus multi-core processors, is ideal for application services such as 3G/4G Wireless and IPTV that demand wire-speed IP packet processing. By enabling data and control plane services in the same form factor, the AT2-5800 provides efficient packet processing as well as significant performance and cost advantages.

The AT2-5800 blade is designed to enable rapid application development using open, modular, highly available systems based on AdvancedTCA architectures. Dual Cavium OCTEON 16-core CN5860-SCP processors 750MHz with 2 Mbyte of shared L2 cache memory provide up to 10 Gbit/s line-speed core processing for network Layers 2-7. With dual 16-core processors, this blade has 32 MIPS64 cores for high-speed packet processing.

To optimize application performance, the CN5860-SCP supports a dual-issue, five-stage pipeline and optimized latencies as well as auto instruction pre-fetching and advanced data pre-fetching features to minimize memory delays.

This packet processor AdvancedTCA blade can be configured to enable a wide variety of applica¬tions. Up to 16 Gbyte (8 Gbyte per processor) of high-speed, low-latency DDR2 memory is imple¬mented as packet memory.

Rear Transition Module (RTM) I/O
I/O operations are provided through a RTM. For application flexibility, the AT2-5800 supports multiple RTM configuration options including any combination of up to 10 ports of IEEE 1000BaseT, 1000BaseSX, or 1000BaseLX via Small Form Factor Pluggable (SFP) transceivers.

Software
The AT2-5800 software implementation is a comprehensive development package designed to improve time-to-revenue. The software development package is optimized to simplify application integration for multi-core processor development environments.
Intelligent Platform Magement Interface (IPMI)
Designed for high availability applications, the AT2-5800 includes an Intelligent Platform Management Controller and firmware subsystem that provides blade management services compliant with IPMI v1.5 or v2.0. This includes blade level parameters, monitoring voltage and temperature conditions, maintaining system status, and managing hot swap operations.

At its lowest level, the AT2-5800 software includes a Universal Boot loader (U-Boot) and a compre¬hensive Power On Self Test (POST) embedded in the firmware. U-Boot loads user application code from the network (e.g. TFTP server) or via local Flash memory.

A Linux Support Package (LSP), Application Program Interface (API) and sample applica¬tion code designed to exercise the AT2-5800 are provided to aid in application development. The Linux Support Package includes Wind River Carrier Grade Linux Operating System (PNE-LE) with Cavium Software Development Kit and user application diagnostics. Other operating systems are available upon request.
