Challenges of Implementing Artificial Intelligence in Embedded Systems

The field of AI has seen notable advancements in recent years, with applications ranging from virtual assistants to autonomous vehicles. Furthermore, advances in LLMs (such as ChatGPT) have enabled the creation of all kinds of content, including emails, stories, artwork, and even music. However, as AI technologies become more prevalent in embedded designs, a new set of challenges has emerged, threatening to slow progress in this area. 

One of the most pressing issues facing AI-embedded designs is the high energy consumption associated with these systems. The demand for processing power in AI applications often leads to increased energy usage, which can drain batteries quickly and limit the overall efficiency of the device. For devices connected to mains power, this high energy usage is quickly reflected in high electric bills (in my case, a room heated to 55 degrees Celsius and a very painful bill).

Additionally, the limited battery life of embedded AI devices poses a significant hurdle in their widespread adoption. Users expect seamless functionality from their devices without the constant need for recharging, making it crucial for AI designs to find a balance between performance and energy efficiency. In such applications, heat dissipation further adds to these challenges, as the continuous operation of AI systems can generate significant amounts of heat, potentially leading to overheating and performance degradation.

Furthermore, the size constraints inherent in embedded designs present a unique set of obstacles for AI technologies. The need to fit complex AI algorithms and processing units into compact devices calls for creative solutions to optimise space utilisation without compromising performance. While existing solutions have attempted to address these challenges by prioritising energy efficiency over raw processing power, this approach often results in a trade-off that limits the full potential of AI applications.
