A 75.6Gb/S 22-Bit Floating-Point Reconfigurable DSP Accelerator Embedding 2048×256-Point Complex FFT and 26K-Point 1-D Signal Processing
77 GHz band millimeter-wave radar is a highly popular research topic with broad application prospects in areas such as autonomous driving. However, as shown in Fig. 1, with the advancement of radar technology, the performance requirements for dedicated DSP accelerators [1–4] have also risen, presenting the following new challenges:1) Diversified computational tasks based on dynamically changing data flows, necessitating efficient execution of different workloads, 2) Demands for increased resolution and range for detection, requiring large-scale processing elements (PEs) with real-time low latency, 3) Desire for better data accuracy and multi-channel inputs, leading to high data throughput.
