AI Technical Summary
Existing FPGA target detection post-processing suffers from bottlenecks such as large DFL decoding latency, fixed confidence filtering thresholds that cannot adapt to dynamic load changes in the NMS module, and the need for data to pass through off-chip memory between modules.
An adaptive FPGA post-processing accelerator system was designed, which integrates a DFL pipeline decoding module, a confidence filtering module, a dual-mode NMS module, and a dynamic congestion control module to achieve low-latency on-chip pipelined processing. The confidence threshold is adjusted through closed-loop feedback to adapt to the dynamic load changes of the NMS module.
It significantly reduces data migration latency and storage bandwidth usage, avoids processing unit congestion, ensures continuous and efficient pipeline operation, and achieves low-latency target detection post-processing.
