2025 Dynamic Quantization and Pruning for Efficient CNN-Based Road Sign Recognition on FPGA
abstract
In this paper, we present an optimized implementation of Convolutional Neural Network (CNN) for road sign recognition on an FPGA platform, utilizing dynamic quantization and pruning techniques. Traditional CNN models are computationally intensive and require significant memory, which poses challenges for deployment on resource-limited hardware such as FPGA. To address these challenges, a hybrid approach was proposed combining dynamic quantization with pruning, allowing layer-specific precision adjustment while removing unnecessary network connections. This method significantly reduces the computational complexity and memory usage while maintaining high accuracy in road sign recognition tasks. The quantized and pruned model is implemented on the Tang Primer 25K FPGA, demonstrating efficient hardware utilization and real-time performance. Experimental results show that the proposed approach substantially reduces power consumption and resource utilization, with minimal impact on accuracy, making it highly suitable for embedded systems and edge computing applications.

2025 Interactive Pattern Repetition Game Design Utilizing Real-Time Hardware Pseudo-Random Number Generator
abstract
This paper presents the design and implementation of a hardware-based memory game developed on an FPGA platform to promote cognitive stimulation among older adults. The game features a 3×3 LED and switch matrix that displays pseudo-random light patterns that users must recall and replicate. To enhance randomness, a seed is extracted from ambient electromagnetic noise using an Analog-to-Digital (ADC) and fed into a multi-Linear Feedback Shift Register (LFSR) pseudo-random number generator (PRNG). The PRNG employs XOR-combined LFSRs initialized with non-overlapping seed transformations to ensure statistical independence. A finite state machine (FSM) governs the game logic, translating 9-bit PRNG outputs into spatial LED patterns and evaluating user input for correctness. Statistical analyses of PRNG outputs, using normality tests and Central Limit Theorem-based smoothing, verify the Gaussian conformity and entropy quality of generated sequences. The fully integrated system includes custom PCBs for ADC input, a mechanical button interface, and an LED display, housed in a 3D-printed enclosure. Results from both simulation and hardware validation confirm the system's effectiveness in generating high-quality randomness and delivering a simple, tactile, and accessible cognitive exercise platform.

abstract
The adoption of IoT enabled devices have led to higher risks of EMI issues, especially in their power management. Particularly, rectifiers for IoT devices are especially concerning. To mitigate this, one approach is to use wide-bandgap semiconductor devices for power management, which reduces the devices' susceptibility and emission of conducted EMI. One such example are GaN semiconductors. However, for low voltage, low frequency systems, the literature concerning GaN performance with regards to conducted EMI have been sparse. This is particularly important for industries such as the medical field which might require low voltage power circuits with components more adept to handling EMI. In this paper, an evaluation will be carried out to compare transistors' performance in the design of a low voltage, low frequency rectifier of 12 Vac at 50 Hz.
