MPC8544DS
Integrated media and communications processor development system
Overview
The MPC8544DS reference platform
is ideal for hardware and software
development for embedded applications.
It leverages Freescale’s highly integrated
MPC8544E processor built on Power
Architecture™ technology and
leading-edge external components.
The high level of integration in the MPC8544E
helps to lower system costs, improve
performance and simplify board design.
The MPC8544E microprocessor supports
dual-enhanced three-speed Ethernet
controllers (eTSEC), multiple PCI Express®
ports (dual x 4 and a single x 1), a 32-bit
PCI controller, 4-channel direct memory
access (DMA), dual universal asynchronous
receiver/transmitter (DUART), serial
peripherals, general purpose I/O and system
timers. The MPC8544E also integrates a
hardware encryption block that supports
different algorithms for high-performance
data that is critical for supporting secure
communications. A board support package
(BSP) is pre-installed on the MPC8544DS.
This BSP consists of a boot loader (u-boot)
and a generic Power Architecture™
technology system based on the Linux®
kernel. The u-boot binary and the Linux
kernel reside in the on-board flash memory
with a file system pre-installed on the hard
disk shipped in the MPC8544DS.
The MPC8544DS BSP generation takes
advantage of the Linux Target Image Builder
(LTIB), a suite of tools that leverages existing
open source configuration scripts and source
code packages and bundles them all into a
single BSP generation bundle. The source
code packages include boot loader and Linux
kernel sources as well as many user-space
source code packages to build a complete
BSP. The LTIB also provides compiler
packages required to build the BSP. Freescale
developers use the LTIB to create BSPs for a
multitude of Freescale development markets.
The LTIB leverages as many BSP elements as
possible for the Freescale markets supported,
while offering the flexibility necessary to
customize components that require platform
specific modifications.
Many third-party applications are available
for the MPC8544DS. They are typically
built on top of the BSP delivered by
Freescale and can installed on the hard
disk. To see demonstrations or to acquire
details of Freescale’s third-party applications
for this platform, please contact your local
Freescale sales office.
