The Autonomous Vehicle Computing Consortium (AVCC), a global collaboration of automotive and technology industry leaders in automated and assisted driving compute solutions, has released two key technical reports, developed to provide the basis for a common autonomous vehicle language, conceptual system architecture, as well as use cases for automated and assisted driving compute systems.
Paul Hughes, chair of AVCC technical committee and lead system architect and distinguished engineer at Arm, says: “The path to a truly autonomous future is paved with foundational technology and computing challenges requiring industry collaboration.
“The new technology reports from the AVCC are a result of key industry players working together to establish a common language and frame of reference for critical autonomous applications, taking us a step closer to a safe, truly autonomous future.”
TR-001 Conceptual Architecture for Automated and Assisted Driving Systems
This reference document offers the AVCC conceptual system architecture for automated and assisted driving compute systems. It is designed to align with the SAE International 1-5 levels of driving automation.
This is the base framework for future AVCCs recommendations:
- creates a common language and functional block diagram;
- breaks down the overall driving compute system into several modular sub-systems and their information exchange; and
- highlights signalling and component interactions.
Topics go beyond the functional block diagram to cover underlying compute elements, example workloads and the related AVSC industry standards. This includes compute functions, data marshalling, connectivity (internal and external), module interoperability, availability, and power metrics.
Volker Hampel, chair of the system architecture working group and group head IC solutions base development at Continental, says: “This paper essentially is a guide to understand the AV compute system architecture, its information flow, and our terminology.
“The functional block diagram is a great tool to foster better communication and expedite innovation.”
TR-002 Functional Guide to Image Signal Processing
This paper provides established industry practices and use cases for Image Signal Processing (ISP) to help expedite industry growth of automated and assisted driving vehicles.
Contents are limited to the ISP domain, which starts at the output of the imaging sensors to the output of the pre-processing blocks.
This implementation agnostic reference document, and:
- provides performance and functional portability recommendations and address interoperability requirements of the image formats and image functions; and
- defines how imaging functions pre-process camera data before it is further processed by detection and sensor fusion algorithms.
Topics include the conceptual ISP architecture highlighting operation, image format, KPIs, precision, throughput, as well as real-time imaging.
Jonas Hammarstrom, chair of the AVCC imaging working group and director pre-development vision of Veoneer, says: “This document highlights the tools we have to process images and data which should help facilitate industry growth.
“The workflows, operation recommendations and benchmarks offer a great guide to understanding the various enhancement modules and options within ISP systems.”
