iMX27 CPU Description：

In response to the needs of design engineers tasked with pushing the performance envelope, packing in a lot of connectivity options and providing robust security in mobile device designs, Freescale presents the i.MX27 multimedia applications processor. Derived from the popular i.MX21 processor and based on the ARM926EJ-S™ core, the i.MX27 processor adds an h.264 D1 hardware codec for high-resolution video processing, an Ethernet 10/100 MAC, security, plug-and-play connectivity and more power management features. This rich feature set makes it an excellent choice for video- and voiceover- IP (V2IP) cordless and mobile phones, intelligent remote controls, point-of-sale terminals and many other wireless applications.
