The Marriage of AI and Safety in Automotive SoCs 
Fergus Casey, Director, R&D, ARC Processors, Synopsys 

As the automotive industry looks beyond Level 2 (Driver Assist) designs, the race is on to deliver high-performance safety-critical autonomous vehicle components powered by the latest AI technology. AI techniques can provide increased accuracy for object and pedestrian detection, but these designs must still meet the ISO 26262 standard’s most stringent level of functional safety and fault coverage. In this presentation, we analyze an autonomous driving use-case emphasizing the need for the inseparable union of AI and safety. We will discuss how Synopsys achieves this marriage without significant impact on performance, power, or area compared to non-ASIL Ready processors. From an understanding of this use-case and requirements, we present an embedded SoC solution providing the highest level of safety without compromising AI performance.

From architecture through to tape-out, we provide an overview of the design, verification, and safety methodologies required for SoC safety certification.

Vinay M K, Co-founder and Vice President, PathPartner 

Cars are more than just transportation – they provide entertainment, communication, convenience, and more. The ideal in-cabin experience is personalized to each occupant in the car to enhance aesthetics and entertainment as well as safety and automotive performance. Offering personalized experiences gives car manufacturers a way to differentiate their products from other options in the market. In this presentation, we will discuss how designers and system architects can enhance in-cabin personalization with face recognition, micro radar, iris scanning, and other sensor fusion technologies to implement, for example, driver drowsiness alerts. We will explain how driver and passenger recognition can be the key enabler for personalization targets, and how to provide this functionality with limited impact on power and area. Finally, we will explore the types of CNN networks available for recognizing actions/expressions and how recognition can provide semantic context.

Yudhan Rajoo, Sr. Technical Marketing Manager, Synopsys 

Developing new AI applications requires implementing cutting-edge technologies while meeting performance, power, area and time-to-market requirements. Edge applications require low power, while CNN engines can be especially challenging to a design’s power budget due to the density of the multiply-accumulates needed to run large neural network computations. In addition, designers can face tedious and time-consuming iterations for floor planning and routing in order to meet PPA targets. This presentation will describe how usage of specialized logic cells and memories can address specific RTL-to-GDSII implementation challenges for CNN engines while reducing time-to-tapeout with optimal PPA. We will show a case study describing how utilizing the HPC Design Kit of logic libraries and embedded memories optimized for the DesignWare EV61 Embedded Vision Processor resulted in lower power and faster design closure.

Enabling Ultra-High Performance, Low-Power 5G Modem Designs with Heterogeneous Multicore Systems 
Pieter van der Wolf, Principal Product Architect, Synopsys 

The 5G standard pushes the requirements on wireless communications equipment for greater than 1Gbps data rates as well as reducing system latency, allowing an expansion of 5G use cases to automotive and other timing-critical applications. SoC modem developers for 4G systems previously met performance requirements with heterogeneous systems, using multiple task-specific processor cores. 5G modem SoCs for user equipment (mobile devices) will need to take the heterogeneous implementation further to provide greater performance for higher data rates, larger MIMO configurations and lower latency, while maintaining similar power budgets to 4G modems. This session will go through the range of digital signal processors, controller cores and task-specific cores that will allow 5G modem SoC developers to implement the required amount of programmability/flexibility in their design, while achieving the performance and low power requirements.

Accelerating Group Theoretic Cryptography with ARC APEX Instructions 
Drake Smith, Vice President of Development, SecureRF 

This presentation will describe how a mathematically efficient cryptographic operation is significantly sped up using the ARC Processor EXtension (APEX) technology. We will give a brief overview of the underlying math operations and how they are implemented in software only. Then we will outline our approach at offloading the most compute-intensive operations onto hardware together with the design process we followed using Synopsys ARChitect, MetaWare, and Intel Quartus Prime. Attendees will see a comparison of the resulting performance metrics with APEX versus an assembly language-only implementation.

The design example will use a fast, small-footprint, and low energy digital signature algorithm that has immediate applicability for a wide range of IoT solutions and is ideally suited for applications where an ARC processor may need to securely communicate with an 8- or 16-bit device. Attendees will learn how to incorporate this and other security methods into their own ARC-based designs.
