SLAAM Board

· The SLAAM board is designed for the exploitation of real-time numeric data thanks to a set of 2 FPGAs Xilinx Virtex 4 interconnected. Its capacity to integrate powerful signal processing algorithms associated with several types of high speed busses. Thanks to the embarked PowerPc processors, the mixed developments C / VHDL facilitates the implementation of real-time solutions much more powerful than on workstation.

· Its wide range of high speed IO authorizes it to work in diverse modes: real time, distant replay or memory replay.

· Its modularity intends it for the most diverse applications: she can, indeed, be used Standalone thanks to its Compact flash and ATX power supply or in complex systems (rack mounted) where several SLAAM cards may be orchestrated by the same computer via a Compact PCI bus.
