LSI 推出新型 Axxia 通信处理器,为移动基础设施提供优化型低功耗解决方案

LSI 公司推出面向多无线电基站和无线回程等设备的 ACP3423 通信处理器,进一步扩展了 Axxia 通信处理器系列产品。Axxia 通信处理器系列使 OEM厂商能够为视频流、网络浏览和高质量数字语音等无线应用提供确定的性能。

 

ACP3423 是采用 LSI 非对称多核架构构建的下一代通信处理器。ACP3423 通信处理器支持同步以太网,这对全 IP/以太网网络中部署的基站和信元位置设备高精度频率同步至关重要。ACP3423 还支持 IEEE1588v2 TOP 时序同步。

 

ACP3423 通过底层 SoC 架构支持快速功能优化,预计相对于性能优化的 ACP3448 而言可将功耗降低多达 35%,同时支持高达 10Gb/s 的有线传输性能。该处理器与 Axxia 系列的其他产品实现了引脚和软件兼容,并提供较少引脚数量的封装版本,可最小化板级空间。Axxia 系列中的软件兼容性使客户能够充分利用现有设计,从而缩短新产品上市时间。

 

ACP3423 通信处理器采用两个运行速度高达 1.6GHz 的 PowerPC 476FP 处理器内核以及包括业界领先的包分类、流量管理、安全处理和深层数据包检测等在内的广泛系列智能专用引擎。Axxia 系列的核心非对称多核架构能够通过专用引擎处理大量无线流量,从而实现低时延、快速路径处理,且不会对 CPU 群产生任何负载。片上处理单元通过 LSI Virtual Pipeline 技术整合在一起,能在不同流量负载条件下提供确定的性能。ACP3423通信处理器包括 1 个 XAUI 和 8 个 SGMII 端口以及 PCIe 和 sRIO 接口。

 

ACP3423 和 ACP3421 通信处理器目前已向网络 OEM 厂商推出。LSI 将于本周在西班牙巴塞罗那举行的世界移动通信大会期间演示 ACP3423 通信处理器。作为综合 Multicore Done Right 计划的一部分,不断扩展的 LSI Axxia 系列产品为无线基础设施提供了业界一流的解决方案。
