Embedded platforms have become an integral part of our daily lives, revolutionizing our technological interaction. These platforms, equipped with deep learning algorithms, have opened a world of possibilities, enabling smart devices, autonomous systems, and intelligent applications. Therefore, the deployment of deep learning algorithms on embedded platforms is crucial. It involves the process of optimizing and adapting deep learning models to run efficiently on resource-constrained embedded systems such as microcontrollers, FPGAs, and CPUs. This deployment process often requires model compression, quantization, and other techniques to reduce the model size and computational requirements without sacrificing performance.

The global market for embedded systems has experienced rapid expansion, expected to reach USD 170.04 billion in 2023. As per the precedence research survey, it is expected to continue its upward trajectory, with estimates projecting it to reach approximately USD 258.6 billion by 2032. The forecasted Compound Annual Growth Rate (CAGR) during the period from 2023 to 2032 is around 4.77%. Several key insights emerge from the market analysis. In 2022, North America emerged as the dominant region, accounting for 51% of the total revenue share, while Asia Pacific held a considerable share of 24%. In terms of hardware platforms, the ASIC segment had a substantial market share of 31.5%, and the microprocessor segment captured 22.3% of the revenue share in 2022.

Embedded platforms have limited memory, processing power, and energy resources compared to traditional computing systems. Therefore, deploying deep learning algorithms on these platforms necessitates careful consideration of hardware constraints and trade-offs between accuracy and resource utilization.

The deployment includes converting the trained deep learning model into a format compatible with the target embedded platform. This involves converting the model to a framework-specific format or optimizing it for specific hardware accelerators or libraries.

Additionally, deploying deep learning algorithms on embedded platforms often involves leveraging hardware acceleration techniques such as GPU acceleration, specialized neural network accelerators, or custom hardware designs like FPGAs or ASICs. These hardware accelerators can significantly enhance deep learning algorithms’ inference speed and energy efficiency on embedded platforms.

Deep learning algorithms must meet the timing requirements of specific applications, ensuring prompt and efficient execution of the inference process. Balancing real-time demands with the limited resources of embedded platforms requires careful optimization and fine-tuning.

If the deployed model doesn’t meet the desired performance or resource constraints, an iterative refinement process may be necessary. This could involve further model optimization, hardware tuning, or algorithmic changes to improve the performance or efficiency of the deployed deep learning algorithm.

Throughout the deployment process, it is important to consider factors such as real-time requirements, latency constraints, and the specific needs of the application to ensure that the deployed deep learning algorithm functions effectively on the embedded platform.

Frameworks and Tools for Deploying Deep Learning Algorithms

Several frameworks and tools have emerged to facilitate the deployment of deep learning algorithms on embedded platforms. TensorFlow Lite, PyTorch Mobile, Caffe2, OpenVINO, and ARM CMSIS-NN library are among the popular choices, providing optimized libraries and runtime environments for efficient execution on embedded devices.
