Cobra PXIe High Speed Recorder


Cobra PXIe High Speed Recorder

The Cobra PXIe High Speed Recorder from Conduant is a unique solution for high speed data recording and playback. The system is designed around PXI Express system architecture, providing a modular and flexible solution that can be customised to suit many different requirements.

The main recording engine combines a PXIe board with high speed RAM and a high performance Xilinx FPGA. This Xilinx FPGA board manages the data movement to and from storage devices, and also provides fibre optic channels for high speed data input or output. The Cobra board can be used alone or in conjunction with additional Cobra units to reach datastreaming performance of over 17 GB/s.

A typical system configuration includes an Intel processor based controller, one or more Cobra boards and SSD based storage boards.
