Edge AI increasingly requires models that learn and adapt on-device under a tight energy budget. Mainstream deep learning models, while powerful, are often overparameterized, energy-hungry and dependent on cloud connectivity. Brain-Like Neural Networks (BLNNs), such as the Bayesian Confidence Propagation Neural Network (BCPNN), propose a neuromorphic alternative by mimicking cortical architecture and biologicallyconstrained learning. They offer sparse architectures with local learning rules and unsupervised/semi-supervised learning, making them well-suited for low-power edge intelligence. However, existing BCPNN implementations rely on GPUs or datacenter FPGAs. This work presents the first embedded FPGA accelerator for BCPNN on a Zynq UltraScale+ SoC (ZCU104) using High-Level Synthesis. We implement both online learning and inference-only kernels with configurable precision (FP32, FP16, and mixed FP16/FXP16). Evaluated on MNIST, Pneumonia, and Breast Cancer datasets, our accelerator delivers up to 17.55% lower latency and 94.1% energy savings over ARM baselines. Our work brings practical, brain-like online learning and scalable inference to edge devices.
