The Right Stuff: A Past and Future History of Automotive Connectivity

By Amir Bar-Niv, VP of Marketing, Automotive Business Unit, Marvell

and Mark Davis, Senior Director, Solutions Marketing, Marvell

In the blog, Back to the Future – Automotive network run at speed of 10Gbps, we discussed the benefits and advantages of zonal architecture and why OEMs are adopting it for their next-generation vehicles. One of the biggest advantages of zonal architecture is its ability to reduce the complexity, cost and weight of the cable harness. In another blog, Ethernet Camera Bridge for Software-Defined Vehicles, we discussed the software-defined vehicle, and how using Ethernet from end-to-end helps to make that vehicle a reality.

While in the near future most devices in the car will be connected through zonal switches, cameras are the exception. They will continue to connect to processors over point-to-point protocol (P2PP) links using proprietary networking protocols such as low-voltage differential signaling (LVDS), Maxim’s GMSL or TI’s FPD-Link.

The Race Against Automotive Hackers Is Accelerating

By Hari Parmar, Senior Principal Automotive System Architect, Marvell

“In your garage or driveway sits a machine with more lines of code than a modern passenger jet. Today’s cars and trucks, with an internet link, can report the weather, pay for gas, find a parking spot, route around traffic jams and tune in to radio stations from around the world. Soon they’ll speak to one another, alert you to sales as you pass your favorite stores, and one day they’ll even drive themselves.

While consumers may love the features, hackers may love them even more.”

The New York Times, March 18, 2021

Hacking used to be an arcane worry, the concern of a few technical specialists. But with recent cyberattacks on pipelines, hospitals and retail systems, digital attacks have suddenly been thrust into public consciousness, leading many to wonder: are cars at risk, too?

Not if Marvell can help it. As a leading supplier of automotive silicon, the company has been intensely focused on identifying and securing potential vulnerabilities before they can remotely compromise a vehicle, its driver or passengers.

Unfortunately, hacking cars isn’t just theoretical – in 2015, researchers on a laptop commandeered a Jeep Cherokee 10 miles away, shutting off power, blasting the radio, turning on the AC and making the windshield wipers go berserk. And today, seven years later, millions more cars – including most new vehicles – are connected to the cloud.

Designing energy efficient chips

By Rebecca O'Neill, Global Head of ESG at Marvell

Today is Energy Efficiency Day. Energy, specifically the electricity consumption required to power our chips, is something that is top of mind here at Marvell. Our goal is to reduce power consumption of products with each generation for set capabilities.

Our products play an essential role in powering data infrastructure spanning cloud and enterprise data centers, 5G carrier infrastructure, automotive vehicles, and industrial and enterprise networking. When we design our products, we focus on innovative features that deliver new capabilities while also improving performance, capacity and security to ultimately improve energy efficiency during product use.

These innovations help make the world’s data infrastructure more efficient and, by extension, reduce our collective impact on climate change. The use of our products by our customers contributes to Marvell’s Scope 3 greenhouse gas emissions, which is our biggest category of emissions.

Marvell Brightlane Technology and OMNIVISION Partnership on Display at AutoSens Brussels

By Katie Maller, Senior Manager, Public Relations, Marvell

Building on our leadership in Ethernet camera bridge technology, Marvell is excited to work with OMNIVISION and to have been a part of their automotive demonstrations at the recent AutoSens Brussels event. OMNIVISION, a leading global developer of semiconductor solutions, partnered with Marvell to demonstrate its OX03F10 (image sensor) and OAX4000 (image signal processor) with our industry first multi-gigabit Ethernet camera bridge, the Marvell® Brightlane™ 88QB5224.

The combined solutions allow camera video that would otherwise be transported via point-to-point protocol to be encapsulated over Ethernet, thereby integrating cameras into the Ethernet-based in-vehicle network. The solutions work with both interior and exterior cameras and are ideal for SVS and other applications in which numerous cameras are utilized and the output of those cameras is used by multiple subsystems or zones.

“Ethernet is the foundation of the software-defined vehicle. By using the Ethernet camera bridge from our Brightlane automotive portfolio to connect cameras to the zonal Ethernet switch, the cameras are integrated into the end-to-end, in-vehicle network,” said Amir Bar-Niv, vice president of marketing for Marvell’s automotive business unit. “Standard Ethernet features such as security, switching, and synchronization are now available to the camera system, and a simple software update is all that’s required when porting the system from one automobile model to another. Shorter runs to the zonal switches reduce the cable cost and weight, as well.”

The demonstrations in the OMNIVISION booth were well received at AutoSens Brussels, an annual event that brings together leading engineers and technical experts from across the ADAS and autonomous vehicle supply chain.

Ethernet Camera Bridge for Software-Defined Vehicles

By Amir Bar-Niv, VP of Marketing, Automotive Business Unit, Marvell

Automotive Transformation

Smart Car and Data Center-on-wheels are just some of the terms being used to define the exciting new waves of technology transforming the automotive industry and promising safer, greener self-driving cars and enhanced user experiences. Underpinning it all is a megatrend towards Software-defined Vehicles (SDV). SDV is not just a new automotive technology platform. It also enables a new business model for automotive OEMs. With a software-centric architecture, car makers will have an innovation platform to generate unprecedented streams of revenue from aftermarket services and new applications. For owners, the capability to receive over-the-air software updates for vehicles already on the road – as easily as smartphones are updated – means an automobile whose utility will no longer decline over time and driving experiences that can be continuously improved over time.

This blog is the first in a series of blogs that will discuss the basic components of a system that will enable the future of SDV.

Road to SDV is Paved with Ethernet

A key technology to enable SDVs is a computing platform that is supported by an Ethernet-based In-Vehicle network (IVN). An Ethernet-based IVN provides the ability to reshape the traffic between every system in the car to help meet the requirements of new downloaded applications. To gain the full potential of Ethernet-based IVNs, the nodes within the car will need to “talk” Ethernet. This includes devices such as car sensors and cameras. In this blog, we discuss the characteristics and main components that will drive the creation of this advanced Ethernet-based IVN, which will enable this new era of SDV. 

But first let’s talk about the promises of this new business model. For example, people might ask, “how many new applications can possibly be created for cars and who will use them?” This is probably the same question that was asked when Apple created the original AppStore, which started with dozens of new apps, and now of course, the rest is history. We can definitely learn from this model. Plus, this is not going to be just an OEM play. Once SDV cars are on the road, we should expect the emergence of new companies that will develop for the OEMs a whole new world of car applications that will be aligned with other megatrends like Smart City, Mobility as a Service (MaaS), Ride-hailing and many others.
