Why Bespoke GPUs designed specifically for automotive use are particularly important.How vehicle manufacturers develop highly interconnected software and operating systems to control many complex vehicle systems in a vehicle.How to drive data can be used without failover to the automotive GPU safely. Less than one in four people consider power and performance as their primary concern when purchasing a modern car, compared to one-third of them for vehicle comfort and user experience. This fact quickly caught the attention of automakers – the new battlefield in the automotive specialty has slipped from under the bonnet to the cockpit.
Many manufacturers have been in business for centuries, not for centuries. During that time, he became a specialist in hardware, drive trains to chassis, and BHP to RPM. But in modern and futuristic vehicles, hardware is not enough without a beautiful, efficient user front end.
Silicon – new desire to run a new machine computing has become the basis in all aspects of the operation of vehicles. There is a lot of talk about Advanced Driver Assistance Systems (ADAS) and Autonomous Driving (AD), but everything from engine management and emissions control to climate and human-machine interface (HMI) is powered by general-purpose graphics processing units ( GPGPUs).
With greater reliability in GPUs, it is not enough to attempt to modify overall solutions; They often dine in the living area and relax with impractical space and heating needs. In the march toward power, inefficient power requirements that could affect the coverage of future electric vehicles (EVs) are one of their biggest problems.
Among these logistics reasons for having an automotive-focused GPU, is the issue of performance safety. If the game console or TV’s GPU crashes, no one will be harmed. However, in an autonomous space, these issues are dangerous. Industry standards such as ISO 26262 and many of ASIL’s safety standards must be incorporated and certified from the outset, such as Imagination Technologies’ PXS series automotive GPUs.
One for all and one for all at the heart of a solid GPU system is the operating system, which is lifelike for carrying data around the vehicle. The automotive industry has made considerable progress in developing globally accepted operating systems. Since 2003, the world’s largest automakers have been working on the automotive open system ARchitecture (AUTOSAR).
By standardizing large areas of the operating system, manufacturers have done a major job of allowing development to remain innovative. When feature designers do not have to go above ground, this eliminates the time it takes to get up to speed and deal with running headaches.It also provides an excellent security web for developers. Using a virtual function bus (VFP), they know that their application or function can basically connect to the rest of the system, even if it uses a unique runtime environment (RTE).
Enabling multiple RTEs using a single VFB allows a central interface point, meaning that these systems can interact with each other. Computers are required to receive and process data input and send hundreds of electronic control units (ECUs) simultaneously to a modern vehicle. Furthermore, the high data-flow utility required for processing by the GPU may not be VFB. It can simultaneously maintain HMI’s operating system (OS) and ensure that critical security functions are performed.
The best strategy is to use multicore GPUs to keep everything safe and well. With multiple cores on a computer, multiple data can be processed simultaneously to reduce delays. This allows unique methods to isolate and process the most important data.
With multiple cores and flexibility, the GPU allows multiple OSes and applications to run on loops on different cores using built-in hardware virtualization since their inception. This means that if a temporary error occurs elsewhere on the GPU, security-critical systems will continue to operate.
OSs like AUTOSAR has helped reduce the cost of upgrading software settings on a car, but storage has not yet returned. On one hand, ADAS and infotainment development are estimated at 20% integrated annual growth between 2030, meaning that it is never important to show a vibrant, rich visual environment in the cockpit.
Cherry CakeMany customers worry about inch edges to inch screens, but size alone does not matter. The growth in 4K display and high-dynamic-range (HDR) content has been significantly higher in the last four to five years. It has gone from premium televisions to mass market and mobile phones. Consumers are beginning to expect this level of loyalty in their vehicles.
With those extra pixels, the need for GPU computing will expand rapidly. It will not be a passive information display – these displays will have many precise and responsive touch-touch interfaces. Studies show that the input delay increases, as well as the accuracy of the work done on the scene.
This is not only an inconvenience that can inhibit the user experience, but it also poses a security risk when distraction and frustration due to input lag attract attention off the road. Another important security element of a cockpit display is the dial and cluster. Previously they were expensive, tough engineering machine clusters, now they are going completely digital. Current speed, gear signal, and alarm light must be provided correctly and input delay will not be tolerated.
To keep everything running smoothly and safely, there are also emerging schools of thought with personal GPS or hybrids that operate with the physical scare light behind the digital panel to operate the dials and clusters independently. Let’s solve this.
These can be strict in design and cost perspective, require more GPU, or restrict the way user interface (UI) dials are delivered. Another approach is Tile Regional Security (DRP), a technology incorporated into the BXS GPU. This may indicate that screen area are of security importance to prioritize and maintain updated information regardless of system conditions.
Full performance rendering is very important in terms of frame rate and delays to create a second pass, which is unacceptable. The DRP breaks the screen into successful tiles and then protects the screen tiles based on their contents (Figure 1). Example of an automobile driver performance divided into DRP tiles. Tiles marked as security-sensitive information are highlighted. Example of an automobile driver performance divided into DRP tiles. Tiles marked with safety-critical information are highlighted.
When asked to self-assess certain key security areas of the screen while rendering, the performance impact is minimal. Another advantage of this system is that it allows energy to be displayed on dials and clusters. Using the same data from Figure 1, the driver changed its performance for monitoring, for example, tire pressure, the DRP is still active (Figure 2). This allows the UI to be customized to facilitate the use of authentication and verification of security-sensitive information. Here, the view of the driver from Fig. 1 shows the wheel pressure on the drive when changing speed and gear indicator for better clarity.
