The system can be expanded by adding a LogicTile Express board to the tile site on the motherboard. This adds a large FPGA for prototyping custom logic blocks alongside the ARM processor. The exported AXI interface from the platform has dedicated routing, directly linking the Test Chip and FPGA. This ensures sufficent bandwidth is available for the user AXI subsystem. To enable early access to hardware the TestChip has not been fully optimized for performance and power.
A microcontroller-based configuration mechanism provides an easy, USB-based plug-and-play method for programming software, firmware and FPGA images into the system flash memory from an attached PC.
