7nm ARM processor for self-driving cars

07.10.2018

ARM introduced the "first standalone class processor with integrated security" - Cortex-A76AE. Designed specifically for the automotive industry, it features Split-Lock technology, a security innovation first available in automotive processors.

Statistically, the vast majority of traffic accidents are the result of driver error, so the transition to self-driving vehicles is expected to reduce crashes and fatalities. However, according to ARM, for this initially it is necessary to put security measures into the hardware. Meanwhile, existing prototypes are often based on processors that lack even the most basic security-related functionality. In addition, these processors are expensive and cannot boast of high energy efficiency.

As an alternative, ARM introduced "the first standalone class processor with integrated security" - the Cortex-A76AE. Designed specifically for the automotive industry, it features Split-Lock technology, a security innovation first available in automotive processors.

CPU clusters in SoCs can be configured either in Split mode for high performance, where two or four independent processors in a cluster can be used for different tasks and applications, or in Lock mode, where processors are locked into one or two pairs in a cluster for applications with increased security requirements. Clusters can be configured to operate in any combination of modes already on the die.

The advantages of Cortex-A76AE also include low power consumption. The processor is designed for release according to the standards of 7 nm. The manufacturer notes that the ARM Cortex-A76AE is the first processor of the new Automotive Enhanced (AE) line, followed by others.

At the same time, the ARM Safety Ready program was announced, which consolidates ARM's efforts in the field of safety, providing access to them to the company's partners. The Safety Ready program includes current and future ARM products that undergo rigorous functional safety controls, including development to ISO 26262 and IEC 61508. Safety Ready is said to be a one-stop source for software, tools, components, certifications, and standards, which will simplify and reduce the cost of functional security integration for ARM partners.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Electronic helmet for truck drivers 14.04.2024

Road safety, especially for drivers of heavy construction equipment, is a top priority for engineers and scientists. In light of this, the German Fraunhofer Institute for Structural Strength and System Reliability has introduced a new product - an electronic helmet, which is designed to protect drivers from serious injury when driving construction vehicles. A new electronic helmet developed by a team of engineers from the Fraunhofer Institute opens up new perspectives for the safety of truck and construction equipment drivers. The device is capable of monitoring the level of shaking in the car cabin and warning the driver of possible danger. The basis of the helmet's operation is a built-in piezoelectric sensor, which generates electricity during physical deformation. This mechanism allows the device to respond to intense vibrations typical of construction equipment. When the level of deformation exceeds safe values, an alarm system is activated on the helmet, ... >>

Antivitamins instead of antibiotics 13.04.2024

The problem of bacterial resistance to antibiotics is becoming increasingly serious, posing a threat to the effective treatment of infections. In light of this, researchers are looking for new ways to combat superbugs. One of the promising directions is the use of antivitamins that can have an antibacterial effect. Antivitamins, although known as the opposite of vitamins, have proven to be a promising tool in the fight against bacterial antibiotic resistance. A study conducted by scientists from the University of Göttingen in Germany confirmed their potential in creating new drugs to combat dangerous infections. With the rise of antibiotic-resistant superbugs, there is a need to find alternative treatments. Antivitamins are molecules similar to vitamins, but capable of inhibiting bacterial activity without harm to the human body. At the moment, science knows only three antivitamins: rose ... >>

Case ASUS ProArt PA602 11.03.2024

ASUS announces the release of the first case in the ProArt line - PA602. Featuring a front panel, 140mm rear fan, dual 200mm front fans, and support for a 420mm radiator, it delivers the ultimate performance.

ASUS ProArt PA602 is designed to simplify the PC building process and is ready for everyday use with automatic dust detection, built-in PWM control on the front I/O panel power lock, and a wide selection of easily accessible USB ports.

The case provides better all-round cooling and quiet operation. Its front panel has an open grille with 15,5mm vents with 45% porosity and two pre-installed 200mm front-facing fans. These fans are much quieter than standard 120mm or 140mm case fans and provide similar air volume. Durable fans with a wide speed range (300-1000 rpm) and PWM control provide powerful airflow with minimal noise.

A pre-installed 140mm fan at the rear of the case helps in heat dissipation and can automatically stop when needed. Inside the case, dual air deflectors direct airflow where it's needed.

ASUS ProArt PA602 greatly simplifies and optimizes the PC building process, providing ample space for large components. The case is compatible with motherboards up to 12" long and up to 10,9" wide. The maximum height of the CPU cooler is 190mm, and the top heatsink supports models up to 420mm in height.

The chassis supports up to eight 2,5-inch SSDs and four 3,5-inch HDD bays. In addition, there is a physical locking of the power button, which prevents accidental pressing.
