Arria 10 GX Low Profile PCIe Board with QSFP and DDR4 on BittWare Spider Platform

The A10SA4 from BittWare is a low-profile PCIe x8 card based on the Intel Arria 10 GX FPGA. Specifically designed to support large FPGA loads, the board offers an FPGA with up to 1150K logic elements, optional 10/40GbE high-speed networking, and up to 16GBytes DDR4 SDRAM – all of which make it ideal for high performance computing applications.

OpenCL support enables a high-level software-like development flow, which greatly simplifies FPGA development.

Spider Platform for Thermal Performance
The A10SA4 is designed with BittWare’s Spider platform, which is a low-profile PCIe platform optimised for thermal performance. The Spider platform combines a low-profile PCIe form-factor for high density, the ability to run larger loads, and a robust passive heatsink option designed for servers.
