In embedded systems, where limited hardware resources are the norm, optimizing AI algorithms is an essential step for successfully deploying artificial intelligence. Deploying full-scale AI models designed for powerful servers is impractical on devices with limited computational resources, such as wearable health monitors or industrial control units operating in real-time environments. Therefore, engineers employ advanced techniques to reduce model requirements while maintaining their effectiveness:
Optimizing AI algorithms in embedded systems is an intelligent compromise between result quality and hardware limitations.
As embedded artificial intelligence grows in complexity, traditional general-purpose processors like CPUs and GPUs are becoming insufficient. These limitations have driven the development of dedicated hardware optimized for AI operations, which has become a crucial element of modern embedded system architecture. These specialized units enable efficient AI task execution while reducing power consumption and increasing performance.
The use of dedicated hardware for AI not only enhances performance but also unlocks the potential for more advanced applications. These technologies enable real-time processing for tasks such as vision systems, autonomous vehicles, and IoT, where fast and reliable data handling is essential.

What is Field-Programmable Gate Array (FPGA) and why is it used in hardware?
Edge AI, or artificial intelligence operating locally on devices, is becoming a cornerstone of modern embedded systems. Unlike traditional cloud-based models, where data is sent to central servers for analysis, Edge AI enables information to be processed directly on the device. This approach eliminates data transmission latency, significantly reduces costs associated with data transfer, and enhances security and privacy by keeping data at its source.
This technology is driven by optimized AI models, such as those employing quantization and pruning, which adapt neural networks to the limited resources of hardware. Additionally, advancements in specialized chips, like Neural Processing Units and Digital Signal Processors, allow for complex AI computations to be performed in real-time with minimal energy consumption. This makes Edge AI invaluable in numerous fields, from advanced driver-assistance systems (ADAS) to industrial applications where reliability and speed are critical.
Edge AI shifts the computational burden from the cloud to the ‘edge,’ enabling faster, secure data processing—for example, in agricultural drones monitoring crop health or smart home devices managing energy usage.
It’s estimated that between 50% and 60% of all organizations worldwide use AI technology. In light of this knowledge, it is no surprise that AI can swiftly generate a project skeleton that incorporates all the critical components of a system. Want to use FreeRTOS? AI will create a structure with ready-to-use tasks, semaphores, and the necessary configuration steps. Need to quickly initialize GPIO for an STM32 or ESP32? AI-powered tools will select the appropriate pin modes, assign pull-ups or pull-downs, and generate the initialization code. Working on an IoT system? AI will configure Wi-Fi or Bluetooth and integrate protocols such as MQTT, WebSocket, or HTTP, producing ready-to-use communication functions.
This approach is not just a time-saver but also a way to minimize the risk of errors in the fundamental configuration. For instance, AI can tailor the code to a specific microcontroller by leveraging chip databases like STM32CubeMX or ESP-IDF. There’s no need to verify which timer is available on a given chip manually—AI will automatically apply the correct settings. Moreover, templates generated by AI include clear comments and basic documentation, making team collaboration much more efficient.
In practice, this means it’s possible to immediately focus on more advanced tasks, such as algorithm optimization, integrating additional sensors, or implementing ML functions on edge devices.

Solving Challenges in Embedded System Design: Practical Guide
In embedded systems, integrating data from various sources requires not only advanced logic but also meticulous attention to detail. Data can come from sensors, communication modules (Wi-Fi, BLE, ZigBee), hardware interfaces (UART, I2C, SPI), or even the cloud and other devices in an IoT network. The challenge lies in their diversity: differences in formats, delays, update frequencies, or protocols often demand significant effort during implementation. This is where AI reshapes the playing field.
Instead of manually writing code to harmonize data, AI can automate the entire process, normalizing also sensor data on the fly and synchronizing it into a unified model. Imagine an IoT device that collects temperature readings via I2C, analyzes humidity through UART, and simultaneously retrieves weather forecasts from the cloud. Using machine learning algorithms, these data streams can be not only integrated but also processed contextually—for instance, by filling in missing values or eliminating noise. AI can dynamically adjust the integration approach based on changing conditions, such as transmission interruptions or shifting device priorities.
Embedded systems often operate in environments where noise and measurement errors pose significant challenges to precision and reliability. Traditional filtering methods, such as Kalman filters or FFT transformations, while proven, have limitations in scenarios with high variability in parameters. This is where AI steps in to make a difference.
Modern machine learning algorithms, such as neural networks or regression models, can learn noise patterns and deviations based on historical data. Moreover, these models are capable of functioning in real time, dynamically compensating for errors as they occur. In practice, this means reducing the impact of disturbances caused by vibrations, temperature changes, or electromagnetic interference—without the need for manual system calibration. For example, in autonomous vehicles, AI-driven algorithms can filter noise from radar data caused by rain or fog, enhancing object detection and ensuring safety.
From an engineer’s perspective, AI is not only about delivering more precise data but also about saving time and resources. Instead of designing sophisticated analog circuits to minimize noise, machine learning-based software can be deployed, continuously optimizing itself. In domains such as IoT, automotive, or robotics, where the demand for precision is constantly growing, AI provides a competitive edge. For instance, in autonomous vehicles, algorithms can filter out noise in LIDAR or radar signals, improving environmental interpretation and enhancing safety.
Minimizing Latency:
AI in embedded systems often operates in critical applications such as autonomous vehicles or medical devices. Delays can lead to incorrect decisions or reduced performance. Solutions include: implementing algorithms based on temporal distributions (e.g., precise task scheduling in RTOS), leveraging hardware accelerators for fast real-time data processing, and minimizing cloud communication through local data processing (“edge computing”).
Compatibility and Interoperability:
Embedded systems frequently need to interact with other ecosystem components (sensors, resource-constrained devices, cloud). Challenges include: ensuring compliance with communication protocols (MQTT, OPC-UA, Modbus), optimizing data transfer between devices and the cloud to minimize latency, and integrating various hardware standards, such as ARM, RISC-V, or DSP architectures.
Data Security:
AI in embedded systems often processes sensitive data. IT specialists must ensure: securing AI models against attacks, particularly adversarial attacks, encrypting data in real-time (e.g., using AES), and implementing authentication and authorization mechanisms, especially in systems with remote access.
Energy Efficiency:
Embedded AI devices, particularly models with high computational demands, impacts energy consumption. Engineers must optimize performance by employing: real-time task scheduling algorithms (RTOS) that minimize processor activity, dedicated hardware optimized for AI, such as TPUs or NPUs, and “edge AI” models that leverage low power, such as TinyML, enabling computations on battery-powered devices.
Model Updates:
Embedded devices often have a long operational lifespan, while AI evolves rapidly. The most important challenges include: regular updates to AI models without disrupting device operations (OTA – Over The Air updates) and real-time monitoring and evaluation of model quality to detect performance degradation.
