1Overview
MPC8572DS is a high-performance computing, evaluation
and development platform supporting the MPC8572
processor built on Power Architecture technology.
MPC8572DS is optimized to support two high-bandwidth
memory ports for the processor core, as well as the three
PCI-express ports, two of which are dedicated for graphics
or other slot-bas ed cards, and the third dedicated for Linux
I/O with the ULI south-bridge.
MPC8572DS is designed for standard ATX form-factor,
allowing it to be used in a standard ATX chassis. The system
is le ad-free and RoHS-compliant.
