Freescale T4240 QorIQ多核处理器参考设计方案

Freescale公司的T4240 QorIQ是多核处理器,组合了12个双线程的e6500 Power Architecture处理器以及用于网络,通信/数据通信,数据中心,无线基础设备和军用的网络和外设总线接口,工作频率高达1.8GHz,支持64位ISA, 高达1.867 GT/s数据传输速率,三个64位 DDR3/3L SDRAM存储器控制器等.主要用在数据中心,WAN优化控制器,应用控制器,路由器,网关,交换机,应用和存储服务器以及通用嵌入计算系统.本文介绍了T4240 QorIQ主要特性和框图,参考设计板T4240RDB主要特性,框图和详细电路图.
The T4240 QorIQ multicore processor combines 12 dual-threaded e6500 Power Architecture® processor cores for a total of 24 threads with high-performance datapath acceleration logic and network and peripheral bus interfaces required for networking, telecom/datacom, data center,wireless infrastructure, and mil/aerospace applications. The T4160 QorIQ multicore processor combines 8 dual-threaded e6500 Power Architecture® processor cores.
This chip can be used for combined control, datapath, and application layer processing in data centers, WAN optimization controllers, application delivery controllers, routers, switches, gateways, application and storage servers, and general-purpose embedded computing systems. It delivers approximately four times the computing horsepower of the P4080, Freescale’s current flagship QorIQ multicore SoC.
Like other QorIQ SoCs, this chip’s high level of integration offers significant space, weight, and power benefits compared to multiple discrete devices.
