About the Motherboard Express µATX
The Motherboard Express µATX is the basis for a highly integrated software and hardware
development system based on the ARM SMP architecture.
The motherboard provides the following features:
•
Peripherals for multimedia or networking environments.
•
All motherboard peripherals and functions are accessed through a static memory bus to
simplify access from daughterboards.
•
High-performance PCI-Express slots for expansion cards.
•
Consistent memory maps with different CoreTile daughterboards simplify software
development and porting.
•
Automatic detection and configuration of attached CoreTile Express and LogicTile
Express daughterboards.
•
Automatic shutdown for over-temperature or power supply failure.
•
System is unable to power up if the daughterboards cannot be configured.
•
Power sequencing of system.
•
Supports drag and drop file update of configuration files.
•
Uses either a 12V power-supply unit or an external ATX power supply.
•
Supports LogicTile and CoreTile daughterboards to provide custom peripherals, or early
access to ARM core or cluster designs, or production test chips. Supports test chips with
an IO voltage range of 0.8-3.3 volts.
