Space-Based Computing Platform Based on SoC FPGA

The satellite communication network has the advantage of wide coverage and is one of the important development directions of fifth generation network. The traditional satellite data processing method is to transmit data to the ground data center for processing. There are problems such as large bandwidth pressure for the satellite link and poor real-time performance. Facing the increasing demand for on-board computing in satellite networks, building a flexible space-based edge system is an effective means to solve this problem. In this paper, SoC FPGA (System on Chip Field Programmable Gate Array) is proposed as a computing resource of the space-based edge network, and a unified service interface is provided for users. To maximize FPGA resource utilization, we studied the elastic scaling mechanism of FPGA resources. Finally, the computational performance and power consumption efficiency of the SoC FPGA computing platform are verified by experiments.
