FPGA-Based Multi-core Reconfigurable System for SAR Imaging

摘要

With the development of the very large scale integration circuit (VLSI), multi-core processors have been developing fast and provide a novel approach to meet the requirements of modern complex computing. Real-time SAR imaging is always a hard problem to deal with since the huge amount of data and complex processing. Therefore, we design a schedulable and scalable multi-core parallel architecture based on FPGA and map the fundamental Chirp Scaling algorithm to the system. The design of the master control core makes the system highly extensible and the dedicated computing cores are designed to accelerate the process. In addition, the system can meet the real-time requirements, and it performs well in the resource utilization and the FPGA chip takes up a small space as well.
