Smart Edge Devices: Design and Applications

Topic Information

Dear Colleagues,

Edge devices are a critical part of the expanding Internet of Things (IoT) ecosystem. They play a key role in bringing computational power closer to the data source, allowing for faster decision-making, better privacy control, and reduced reliance on centralized cloud computing. Deep learning is increasingly being deployed for edge devices to enable real-time decision-making and intelligent processing directly at the source of data, converting them into smart edge devices. These devices can perform complex tasks such as image recognition, speech processing, and predictive analytics locally without relying heavily on cloud-based computing. This has led to a variety of applications across industries, including healthcare, automotive, manufacturing, and more.

The present Topic aims to publish new knowledge on smart edge devices by bringing together works on the design and applications of these systems. Topics of interest include, but are not limited to, the following:

• Design of smart edge devices:
  • Microprocessors for edge computing;
  • Sensors for data collection;
  • Protocols and modules for connectivity of edge devices;
  • Local storage architectures;
  • Power management systems;
  • Machine and deep learning models for edge computing;
  • Embedded computing architectures;
  • Custom design of accelerators for edge computing;
  • New high-performance devices for embedded deep learning.
• Applications of smart edge devices:
  • Smart healthcare;
  • Industrial automation;
  • Autonomous vehicles;
  • Smart cities;
  • Edge devices in agriculture;
  • Retail and consumer electronics;
  • Energy management;
  • Space data analysis.

To address the challenges of high computational cost and energy consumption posed by deep neural networks in embedded systems, this paper presents CaDCR, a lightweight dynamic collaborative reasoning framework. By integrating a feature discrepancy-guided skipping mechanism with a depth-sensitive early exit mechanism, the framework establishes hierarchical decision logic: dynamically selects execution paths of network blocks based on the complexity of input samples and enables early exit for simple samples through shallow confidence assessment, thereby forming an adaptive computational resource allocation strategy. CaDCR can both constantly suppress unnecessary computational cost for simple samples and satisfy hard resource constraints by forcibly terminating the inference process for all samples. Based on this framework, we design a cascaded inference system tailored for embedded system deployment to tackle practical deployment challenges. Experiments on the CIFAR-10/100, SpeechCommands datasets demonstrate that CaDCR maintains accuracy comparable to or higher than baseline models while significantly reducing computational cost by approximately 40–70% within a controllable accuracy loss margin. In deployment tests on the STM32 embedded platform, the framework’s performance matches theoretical expectations, further verifying its effectiveness in reducing energy consumption and accelerating inference speed.
