Sorting algorithm is an important branch in the image recognition field. In this field, the bitonic sort is one of the typical merge-based parallel sorting algorithms. To meet requirements of performance and power consumption, kinds of accelerator for sorting algorithm were proposed. In this work, an energy-efficient reconfigurable sorting accelerator is designed and integrated into one RISC-V SoC to prove the efficiency. Compared with sorting results on CPU, our accelerator can help achieve 462x times.
