QorIQ<sup>®</sup> T2080

点击播放视频

采用28 nm工艺的QorIQ T2080和T2081通信处理器是配备8个虚拟内核的中端平台，它们融合了T系列旗舰产品T4240的架构创新，如1.8 GHz双线程e6500内核，并具备更低的功耗和价格。

T2080处理器是继恩智浦成功推出P3041和P2041中端系列四核器件后的又一力作，主要用作控制平面或集成的控制和数据平面处理器。它是出色的升级产品，将内核处理能力、缓存大小、SerDes带宽和以太网连接性能提高了两倍以上，同时功耗处于相近的水平。它还为P4080用户提供了一个非常有价值工程设计机遇，因为T2080在提供同等性能的同时，价格和功耗更低。

T2081是T2080的小尺寸版本，与四核的T1042引脚兼容。这就使T1042用户能够在处理需求增加的时候轻松升级产品性能。同时，用户还可以在两种不同性能水平的产品中使用相同的电路板。
