Zonal Architectures Play Key Role In Vehicle Security
By Ann Mutschler - 17 Nov, 2021 - Comments: 1

The automotive ecosystem is starting to shift toward zonal architectures, making vehicle functionality less dependent on the underlying hardware and allowing more flexibility in what gets processed where. The impact of that shift is both broad and significant. For carmakers, it could lead to hardware consolidation and more options for failovers in case something goes wrong with any system in... » read more

An FPGA-Based ECU for Remote Reconfiguration in Automotive Systems
By Technical Paper Link - 15 Nov, 2021 - Comments: 0

Abstract: "Growing interest in intelligent vehicles is leading automotive systems to include numerous electronic control units (ECUs) inside. As a result, efficient implementation and management of automotive systems is gaining importance. Flexible updating and reconfiguration of ECUs is one appropriate strategy for these goals. Software updates to the ECUs are expected to improve performance ... » read more

Shifting Vehicle System Development Left With Virtual ECUs
By Marc Serughetti - 04 Nov, 2021 - Comments: 0

Developing electrical and electronic content for vehicles has always been an engineering and manufacturing challenge. The road is an exceptionally rough environment for components: temperature and humidity change constantly while noise and vibration pummel all parts of the vehicle. The nature of high-speed travel requires safety and reliability, which must be achieved in the presence of the dif... » read more

Changes In Auto Architectures
By Ed Sperling - 04 Aug, 2021 - Comments: 0

Automotive architectures are changing from a driver-centric model to one where technology supplements and in some cases replaces the driver. Hans Adlkofer, senior vice president and head of the Automotive Systems Group at Infineon, looks at the different levels of automation in a vehicle, what’s involved in the shift from domain to zonal architectures, why a mix of processors will be required... » read more

Big Changes Ahead For Connected Vehicles
By Ann Mutschler - 03 Jun, 2021 - Comments: 0

Carmakers are reworking their electronic architectures so they can tap into a growing number of external services and internal options, similar to the way a data center taps into various services over its internal network. In the past, this has been largely confined to internal services such as on-board Internet connectivity, and external traffic routing and music. The current vision is to g... » read more

PowerPR Virtualization: A Critical Feature For Automotive GPUs
By Imagination Technologies - 26 Feb, 2020 - Comments: 0

What is GPU virtualization? Conceptually, virtualization is the capability of a device to host one or more virtual machines (VMs) that each behave like actual independent machines with their own operating system (OS), all running on the same underlying device hardware. In regard to GPUs, this means the capability to support multiple concurrently running operating systems, each capable of submit... » read more

Selecting an Approach to Build Flexible, Cost-Effective ECU Production Test Systems
By NI - 11 Nov, 2019 - Comments: 0

Electronic control units (ECUs) were invented in the 1970s. At that time, people needed to improve fuel economy due to the oil crisis, which meant finding a way to make engines run cleaner and pollute less. Engines used a mechanical device called a distributor to control spark timing and a carburetor to control the fuel mixture. This mechanical system had minimal tuning and adjustment capabilit... » read more

Where Should Auto Sensor Data Be Processed?
By Ann Mutschler - 01 Aug, 2019 - Comments: 0

Fully autonomous vehicles are coming, but not as quickly as the initial hype would suggest because there is a long list of technological issues that still need to be resolved. One of the basic problems that still needs to be solved is how to process the tremendous amount of data coming from the variety of sensors in the vehicle, including cameras, radar, LiDAR and sonar. That data is the dig... » read more

Road Not Fully Constructed
By Ed Sperling - 02 May, 2019 - Comments: 3

There is a growing consensus in the semiconductor industry that SAE Level 3 and Level 4 autonomy will be full of unexpected hazards. At a number of recent conferences in Silicon Valley, experts from all parts of the semiconductor industry have voiced concern about those middle steps between assisted driving and full autonomy. This isn't the public position taken by carmakers and Tier 1s.... » read more

How To Build An Automotive Chip
By Ann Mutschler - 07 Mar, 2019 - Comments: 0

The introduction of advanced electronics into automotive design is causing massive disruption in a supply chain that, until very recently, hummed along like a finely tuned sports car. The rapid push toward autonomous driving has changed everything. This year, Level 3 autonomy will begin hitting the streets, and behind the scenes, work is underway to design SoCs for Level 4. But how these chi... » read more
