New ARM926EJ-S Device – i.MX27

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 vioice-over-IP (V2IP) cordless and mobile phones, intelligent remote controls, point-of-sale terminals and many other wireless applications.

Enhanced Video Capabilities: The i.MX27 has a built-in, low-power eMMA2 hardware block, which consists of an MPEG-4 and H.263/H.264 encoder/decoder for D1 resolution and image pre-processing and post-processing stages. These features provide superb image and video quality.

Devices with the i.MX27 are capable of long video playback time with exceptional video quality (high frame rates and large screen resolution support). The i.MX27 provides flexibility for software implementation for other video decoders, such as PacketVideo®, RealNetworks® and Windows Media™. Hardware code addresses the I/O bottleneck and helps to reduce power consumption, enabling greater device mobility.
