Radiation Tolerant, Low Power Sierra GPU Single Board Computer

High performance data processing capabilities are essential to spacecraft autonomous operations, image processing, data fusion, or AI/ML applications. The Sierra GPU SBC integrates a 75G Flop GPU SoC with a radiation tolerant FPGA on a single extended 3U VPX board. The GPU SoC provides four x86 CPUs, GPU cores, and peripheral I/O such as PCIe and Ethernet. The GPU/FPGA pair, coupled with FMC+ I/O capability, provides a very flexible high performance Heterogeneous Compute Platform (HPC) for computational intensive applications, all in a low SWaP package.Ìý
