i.MX51(i.MX515)处理器概述

飞思卡尔新i.MX515集成了ARM Cortex-A8内核并使用65纳米处理技术制造，提供高达2100 Dhrystone MIPS，性能可从 600MHz 扩展至1GHz。i.MX515处理器包含一些先进电源管理功能，如基于硬件的专用视频加速块，能够延长电池寿命，不再需要风扇和散热片。

　　i.MX515通过将高度集成的器件和低成本印刷电路板融合在一起，飞思卡尔i.MX515解决方案实现了非常低的物料单成本。此外，由于i.MX515具有一个同时支持DDR2和移动DDR1的储存器接口，i.MX515还实现了成本效率。尽管移动DDR1是大多数功率敏感型移动互联网设备的理想选择，但DDR2更适合上网本，因为i.MX515能够以低得多的成本实现低功率。尽管i.MX515能同时支持两者，但目前市场上销售的很多竞争Cortex-A8平台仅提供移动DDR1，从而限制了设计人员最大限度地节约成本的选择。

　　i.MX51是同时提供OpenVG和OpenGL图形内核的仅有的几个处理器之一，因此实现了2D和3D图形以及Flash和SVG，增强了用户体验。 为Adobe Player创建的视频是目前互联网上领先的视频格式之一。通过与Adobe合作，飞思卡尔计划让Adobe软件运行在该处理器的专用OpenVG图形块上，以此延长电池寿命，i.MX515让上网本网络浏览体验具有像传统PC一样丰富内容和响应性。
