CENA讯：3月26日，中国电子信息产业集团有限公司（以下简称“中国电子”）在京召开“CPU与网络交换芯片新品发布暨成果推广会”，网络交换芯片“智桥”SDN智能高密度万兆交换芯片和“飞腾”FT-1500A系列CPU处理器联袂发布。

据天津飞腾总经理谷虹介绍，FT-1500A系列处理器是64位通用CPU，兼容ARM V8指令集，采用国际先进的28nm工艺流片，具有高性能、低功耗等特点，关键技术国内领先，可实现对 Intel中高端“至强”服务器芯片的替代，并广泛应用于政府办公和金融、税务等各行业信息化系统之中。FT-1500A系列目前包括4核和16核两款产品。其中4核处理器芯片主要面向桌面终端和轻量级服务器应用领域，主频2GHz,功耗15W，两个DDR3-1600存储通道，支持电源关断、DVFS等低功耗技术，适用于构建台式终端、一体机、便携笔记本、微服务器等产品；16核处理器芯片面向服务器应用领域，主频2GHz，功耗35W，4个DDR3-1600存储通道，支持虚拟化功能，适用于构建网络前端接入服务器、事务处理服务器、邮件服务器、数据库服务器、存储服务器等产品。

这个具有世界先进水平的FT-1500A系列处理器是64位通用CPU，兼容ARM V8指令集 是个什么东东，先进在哪里。这里介绍如下

ARMv8-A Architecture

The ARMv8 architecture introduces 64-bit support to the ARM architecture with a focus on power-efficient implementation while maintaining compatibility with existing 32-bit software. By adopting a clean approach ARMv8-A processors extend the performance range available while maintaining the low power consumption characteristics of the ARM processors that will power tomorrow's most innovative and efficient devices. The current ARM processors supporting the ARMv8-A architecture are the Cortex-A72, Cortex-A57 and Cortex-A53 processors.

Increased availability of larger registers for general purpose and media instructions, a greater addressing range and cryptography instructions enable new categories of applications for superphone and tablet computing, while bringing the ARM benefits of efficient design and low power consumption to applications where 64-bit computing is already established, such as servers and network infrastructure, promising to revolutionize the data center.

The ARMv8 architecture maintains compatibility with the comprehensive software ecosystem for 32-bit components. This enables a wealth of software optimized for existing ARM processors to benefit from the enhanced performance of processors based on the ARMv8 architecture, while the addition of 32-bit cryptographic instructions further enables optimization for emerging requirements.

Developing the software to make best use of the new 64-bit capabilities requires the availability of excellent tools, test platforms and key open source components. While developing the architecture and the processors based on ARMv8-A, ARM has also ensured that the essential tools for development are available to software developers today, enabling the ARM software ecosystem to continue to innovate around the Architecture for the Digital World.
