As machine learning (ML) algorithms, particularly neural networks (NN), expand in popularity and capacity, the quest for more efficient computation methods gains momentum. Memristor crossbar technology emerges as a promising alternative to traditional computing units, aiming to address traditional computing challenges. However, conventional matrix-vector multiplication (MVM) methods on these platforms are often plagued by device imperfections and drift. In this work, we introduce an innovative lightweight calculation approach leveraging bit-transformation for MVM, significantly enhancing operation precision and, consequently, the performance of ML algorithms on memristor crossbar platforms. We provide details of the core algorithm and its extensions, furnish digital validation, and simulate its efficacy using an autoencoder (AE) neural network with an extended VTEAM model. Our tests demonstrate an average reconstruction precision improvement of approximately 53.5%. This work’s applicability extends beyond NNs, offering a foundational method for conducting more precise analog MVM operations.

Transformers have emerged at the forefront in the training and inference of diverse machine learning tasks, encompassing video processing, image generation and classification, and natural language processing (NLP). Despite their increasing prevalence, a comprehensive framework to efficiently implement them has been lacking. This study introduces a transformer-based framework which accelerates image processing of UNETR (U-shaped neural network transformer) model for video segmentation task using the cityscapes dataset. Given the large size of images in the dataset we incorporate hyperattention and mixed precision in our design. Our model is trained on Google A1OO GPU accelerator and profiled. Finally, our design is implemented on FPGA to take advantage of the reconfigurable and high-throughput characteristics of system-on-chips (SoC) for image processing. Our results indicate improvements compared to existing research in this domain.

Mobile robots are now widely used in numerous real-world applications that have complex navigation requirements, especially in environments used by humans. This requires highly accurate navigation that can be performed in realtime. In this paper, a method for generating a smooth motion of nonholonomic mobile robots is proposed. It enables robots to move optimally toward the desired goal and allows fast path replanning when encountering unknown or dynamic obstacles. The method generates smooth, collision-free trajectories based on clothoids, ensuring high computational efficiency and suitability for realtime path planning. By applying a smoothing algorithm, the proposed method improves the robot's efficiency in terms of travel time and trajectory length from start to goal, as demonstrated by a comparison with model predictive control.

This paper presents a hybrid pipeline SAR ADC with a loop-unrolled structure to reduce the crossbar’s ADC power while maintaining high speed. The 1
st
stage memristive SAR ADC can fully utilize the TIA originally in the crossbar and avoid the extra MDAC in pipeline ADC. Further, memristive weight calibration and a new resistive alternated binary search are implemented on the 1
st
stage to maintain the TIA gain and ADC’s accuracy. Both stage’s ADC are loop-unroll to eliminate the delay brought by SAR logic for high speed. Through multiple simulations, the design is demonstrated to be robust to the frequency and mismatch variations with the highest sampling frequency reaching 300MHz and SNDR up to 65.1dB in 9MHz input. The power consumption is designed to be as low as 6.7mW, which helps the ADC to achieve a 15.2fJ/conv FoM. Not limited to the crossbar, the presented ADC also shows promising potential for applications in various fields (biomedical, IoT etc.) for general purposes.
