Overview
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 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.

i.MX27 Multimedia Applications Processor
The i.MX Family
Freescale’s i.MX family of applications
processors delivers power to the people who
demand it: designers and users alike who want
exceptional performance and long battery life
from their mobile devices. Design engineers
capitalize on the amazing performance i.MX
processors achieve at lower clock speeds
and the high degree of integration to quickly
deliver innovative mobile devices to market.
Consumers love the lifelike video and 3-D
graphics reproduction, quick response and long
play time for hours of work and entertainment
use. Freescale gives design engineers the
power of choice with various i.MX processors,
from the i.MXS for price sensitive applications,
and i.MXL, i.MX1 and i.MX21S for mid-range
devices, to i.MX21, i.MX27, i.MX31L and
i.MX31 for high-performance mobile
multimedia devices.
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.
