BittWare 520N FPGA Accelerator Card

BittWare 520N FPGA Accelerator Card features an Intel Stratix 10 FPGA. The 520N FPGA Accelerator Card offers a single-precision floating-point performance of up to 10 TFLOPS and four banks of DDR4 external memory. The device provides four network ports enabling FPGA-to-FPGA scaling separate from the PCIe bus.

The BittWare 520N FPGA Accelerator Card supports an array of serial I/O protocols operating up at 10/25/40/100GbE. The device provides both traditional HDL and higher abstraction C, C++, and OpenCL-based tool flow support.
