With the expansion of AI-powered virtual assistants, there is a need for low-power keyword spotting systems providing a "wake-up" mechanism for subsequent computationally expensive speech recognition. One promising approach is the use of neuromorphic sensors and spiking neural networks (SNNs) implemented in neuromorphic processors for sparse event-driven sensing. However, this requires resource-efficient SNN mechanisms for temporal encoding, which need to consider that these systems process information in a streaming manner, with physical time being an intrinsic property of their operation. In this work, two candidate neurocomputational elements for temporal encoding and feature extraction in SNNs described in recent literature-the spiking time-difference encoder (TDE) and disynaptic excitatory-inhibitory (E-I) elements-are comparatively investigated in a keyword-spotting task on formants computed from spoken digits in the TIDIGITS dataset. While both encoders improve performance over direct classification of the formant features in the training data, enabling a complete binary classification with a logistic regression model, they show no clear improvements on the test set. Resource-efficient keyword spotting applications may benefit from the use of these encoders, but further work on methods for learning the time constants and weights is required to investigate their full potential.

A traction inverter converts battery energy into power that controls motor torque and speed, giving it the most influence over an EV's range, performance and driving experience. The typical system consists of safety MCU, DSP for realtime motor control processing along with hardware resolver for position sensing. The speed for traction motor is pushed to higher e.g. 10-30K rpm to reduce cost by miniaturizing motor and passive components, which necessitates the realtime control loop performance in uSec range. The paper proposed a single chip traction Inverter System using Texas Instruments (TI) AM263 MCU, which is designed for real-time and high performance for optimal system cost for traction inverter. The paper proposes innovative techniques namely optimized Field Oriented Control (FOC) control algorithm with custom math algorithms, Software based resolver and double PWM update for better control performance. The overall solution is prototyped and demoed on hardware design and measured for overall performance. The real-time performance of control loop is 3.9 usec, which is less than 1% for overall processing power for 10K rpm. The proposed single chip solution has 99% headroom for running AUTOSAR operating system and customer's applications for differentiation.

In surveillance applications, the detection of tiny, lowresolution objects remains a challenging task. Most deep learning object detection methods rely on appearance features extracted from still images and struggle to accurately detect tiny objects. In this paper, we address the problem of tiny object detection for real-time surveillance applications, by exploiting the temporal context available in video sequences recorded from static cameras. We present a spatiotemporal deep learning model based on YOLOv5 that exploits temporal context by processing sequences of frames at once. The model drastically improves the identification of tiny moving objects in the aerial surveillance and person detection domains, without degrading the detection of stationary objects. Additionally, a two-stream architecture that uses frame-difference as explicit motion information was proposed, further improving the detection of moving objects down to 4 x 4 pixels in size. Our approaches outperform previous work on the public WPAFB WAMI dataset, as well as surpassing previous work on an embedded NVIDIA Jetson Nano deployment in both accuracy and inference speed. We conclude that the addition of temporal context to deep learning object detectors is an effective approach to drastically improve the detection of tiny moving objects in static videos.
