In an AI-driven autonomous vehicle system, how do GPUs, CPUs, and DPUs interact during real-time object detection to optimize performance?

The interaction between GPUs, CPUs, and DPUs in an AI-driven autonomous vehicle system is crucial for optimizing performance, particularly during real-time object detection. In this architecture, the GPU is specifically designed to handle parallel processing tasks, making it ideal for executing object detection algorithms. These algorithms often require intensive computations on large datasets, such as camera images, which the GPU can manage efficiently due to its architecture.

The CPU, on the other hand, is responsible for executing the decision-making logic necessary for autonomous navigation. This includes interpreting data processed by the GPU and making decisions about the vehicle's actions based on that data. For instance, the CPU may need to determine how to respond to detected objects, such as stopping to avoid an obstacle or changing lanes.

The DPU plays a critical role in offloading specific tasks from the CPU, particularly those related to data transfer and security. This includes managing the flow of data between the sensors (like cameras) and the processing units, which allows the CPU to focus on higher-level decision-making tasks rather than getting bogged down with data management. Additionally, the DPU can enhance security protocols for the vehicle's data transmissions, ensuring that information is processed safely without compromising real-time performance.
