Freescale i.MX27 Processor Architecture Overview

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

The i.MX27 multimedia applications processor is architected with Freescale’s Smart Speed™ technology, an intelligent integrative approach that uses hardware accelerators to offload the CPU and a crossbar switch to bring parallelism to the system. The result is a processor that performs like a much higher MHz device, but conserves power for long, long battery life.

The i.MX family supports a range of platforms such as those based on the Microsoft® Windows® CE and Linux® operating systems as well as a number of leading RTOSs.
