AI Technical Summary

Technical Problem

Existing autonomous driving systems require a large amount of image data to be transmitted to the host system for processing, resulting in high communication bandwidth requirements and increased computational load, which affects system efficiency.

Method used

The system employs integrated circuit devices to integrate image sensors, image signal processing circuits, and artificial intelligence engines. These are connected via high-bandwidth interconnects to perform local image processing and inference. After generating the inference results, only a small amount of data is transmitted to the host system.

Benefits of technology

It reduces the communication bandwidth requirements of the host system, improves processing efficiency, reduces computational load, and supports highly accurate and efficient image analysis.

Abstract

An integrated circuit device in a single integrated circuit package includes an image sensor, memory, and an inference engine configured to convert images generated by the image sensor into inference results for transmission to a host system for further analysis, and / or generate a more efficient image stream provided in the camera interface. The intelligence provided by the inference engine can reduce or eliminate the amount of image data transmitted to the host system for processing during typical scenarios. The inference results can be automatically stored in the memory, accessible by the host system as a solid-state drive (e.g., using the NVMe protocol). Optionally, the integrated circuit device may have an interface to an external SSD. For example, the integrated circuit device as an SSD and / or the external SSD can be configured as a black box data logger for an autonomous vehicle.
