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 processor 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-on 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 FPGA and processor daughterboards to provide custom peripherals, or early access to processor designs, or production test chips. Supports test chips with an IO voltage range of 0.8-3.3 volts.
