    FPGA-based implementation of the neuron computation, weight storage, decay, and training modules (A) Neuron computation module implemented on FPGA, illustrating the datapath from TTFS-encoded spike trains to the final output score. The module consists of an adder tree for spike accumulation, a membrane potential updating unit, and an output layer that detects threshold crossings based on SNT and updates the output score accordingly. (B) Organization of 4,000 synaptic weights across 20 on-chip block RAMs (BRAMs). Each BRAM stores weights associated with a single output neuron, enabling parallel access to all corresponding synaptic weights during inference and training by fixing the neuron address. (C) Multiplier-free circuit for realizing a fixed decay coefficient D = 0.75 using a shift-and-add structure. Partial results generated by binary shifts are combined through addition to obtain the scaled output, representing a standard hardware-efficient implementation for constant multiplication in FPGA designs. (D) FPGA-based training module implementing fixed-point weight updates using an LReSuMe-based learning rule. The module includes a shift-and-add learning multiplication unit and a zero replacement unit (ZRU) to mitigate quantization-induced null updates.

    Noise modeling, training accuracy comparison, and fixed-point saturation behavior (A) Illustration of impulse noise modeling in the MNIST dataset. From left to right: original image, image corrupted with random impulse noise (random positions and random values), and image corrupted with impulse noise (random positions with pixel values replaced by either 0 or 255). (B) Training accuracy comparison among six different network configurations and quantization settings on the clean MNIST training dataset. Accuracy is reported per 100-image chunk. (C) Evolution of final output scores under different fixed-point formats during training. Results are shown for FPGA Q6.10 (left) and Q6.26 (right) implementations. The x axis denotes the uniformly sampled time step index selected from the first 180 training chunks of the hardware simulation, and the y axis represents the final output score S o j . At each sampled time step, the maximum, mean, and standard deviation of S o j across all output neurons are computed and visualized.
