SonicBrain A10P FPGA Accelerator

Download Datasheet

SonicBrain’s A10P FPGA Accelerator is a 3/4-length PCIe x8 card based on the Intel Arria 10 GX1150 or GX660 FPGA. The Arria 10 FPGAs include high-speed transceivers, embedded Gen3 PCIe x8 and massive number of IEEE 754 compliant hard floating-point DSP blocks that deliver up to 1.5 TFLOPS. The A10P offers flexible memory configurations supporting over 32GB of memory, sophisticated clocking and timing options, and four front panel QSFP cages for 4x 40GbE or 16x 10GbE. All these features make the A10P a powerful PCI-Express computing and I/O platform for FPGA development and deployment across a wide range of applications, including High Performance Computing, AI, Machine Learning, Network Acceleration, Computer & Storage, Broadcast and Data Analytics.
