How Automotive IoT is Shaping Wireless Networks When I bought my car, it was a big deal that it could use bluetooth and sync to my phone for calls and music. The sales guy went on and on about it. I mostly listened to the radio on scan, so this was not a key feature for me, but I’ve come to love the hands-free calling. Last year, my friend bought a newer model of the car, and the bluetooth communication has expanded to maps, Pandora, and other apps. However, they are all still accessed via a Read Article

Impediments to the Implementation of Machine Learning Algorithms in Autonomous Vehicles Machine learning is considered to be the next big step for self-driving cars. You may not know, however, that machine learning cars first hit the road decades ago. One notable example is ALVINN, which stands for Autonomous Land Vehicle in a Neural Network. As its name suggests, ALVINN used a neural network to watch a human driver and learn how to drive itself. The project was a great example of the potential of self-driving cars. It also clearly Read Article

What is Vehicle to Everything Communication Technology and How Will 5G Enable It? Editorial credit: ermess / Shutterstock.com Since cars first started crowding the roads, engineers have been dreaming of how to make traffic move a bit faster. Mechanical engineers made individual cars speedier and more fuel efficient. Civil engineers studied traffic patterns and planned roads accordingly. Now it’s time for electrical and software engineers to get involved with vehicle to everything (V2X) technology. V2X will reduce traffic jams Read Article

Over-The-Air Connectivity Allows Automotive Firmware Updates, but Creates Security Challenges Thanks to the accelerating pace vehicle systems are being computerized, updating and securing control firmware is a new responsibility for automotive manufacturers. Over-the-air connectivity means crucial patches, especially those closing security holes, can be silently pushed to thousands of cars without user intervention. That said, it’s important to realize that an over-the-air solution presents a double-edged sword: if not implemented Read Article

Multiple Sensor Fusion for Unmanned Autonomous Vehicles: Pros and Cons Think back to when you were a child, how did you think the future would look? Spaceships, flying cars, internet connected eating utensils? We have many of the things I hoped we would, but somehow cars have lagged behind. I was expecting to see flying cars zooming through the sky and driverless cars whizzing through the streets. I don’t have a solution for flying cars, but there is something that’s making unmanned autonomous vehicles a reality Read Article

Growing ADAS Market Will Require Efficient Software and MPU Expertise Transportation has a major effect on people and societies, and cars changed life around the world forever. We are now on the brink of another major transportation breakthrough, self-driving cars. While we are still years away from fully autonomous vehicles, advanced driver assistance systems (ADAS) are becoming more common in the automotive industry. The ADAS market is headed for major growth, and smart software developers can grow with them Read Article

Why You Should Use the Best Static Analysis Tool For Developing Autonomous Vehicle Software Designers often focus on benchmarking their compiler, only to have their programs slowed down by safety considerations later. Using a compiler that has integrated safety features, especially static analysis tools, can get your program into ISO 26262 compliance quickly. Using a safety tool with great static analysis can save you time in debugging, keep you from cutting features, and allow you to get the most out of your compiler. Have you ever Read Article

Standalone release of TASKING Safety Checker available TASKING Safety Checker assists embedded software developers with safety-related analysis of application code and providing evidence for Freedom From Interference, for example for certification of automotive software applications conform the ISO 26262 functional safety standard or similar interpretations of IEC 61508 in other industries. The standalone version of TASKING Safety Checker can be used to check embedded code independent from the tool Read Article

Configuring TASKING Safety Checker for Third Party C Compilers TASKING Safety Checker can be used in various industries where IEC 61508 related regulations are in place, like ISO 26262 in automotive. It fully supports the ISO-C standard, but it needs a simple configuration to be used in context with compiler specific C extensions. This blog provides sources for such configurations. In addition to the TASKING C compilers, the new Safety Checker can be configured to work with embedded C compilers from other Read Article

Who is calling whom? The Making of Information Age: Enfield Telephone Exchange1 Safety Checker by TASKING is a Safety integrity level (SIL) aware static analyzer with the ability to check for interference in the memory space domain and the special function register domain which is helpful to prove "freedom from Interference" as described in the ISO 26262 functional safety standard. The success of a good static analysis stands or falls to whether the tool is able to Read Article

ISO 26262 - Best ideas come in the Shower TASKING wants employees to be creative, you get your best ideas when you’re under the shower, so build a couple of showers at the TASKING office. This wonderful idea arose under the shower, so I quickly wiped myself dry and went to the office to tell my boss about it. Unfortunately he was not excited at all. Read how this relates to my experience when developing our Safety Checker, initially targeted for ISO 26262 related applications. Still Read Article

Freedom from Interference - How to beat the MPU Mixed criticality in embedded software development is the concept of allowing software at different levels of criticality to interact and coexist in the same Electronic Control Unit (ECU). Certification of such systems is rather complex, because you have to prove that software elements with a lower safety level cannot interfere with elements with a higher safety level. You have to ensure what ISO 26262 calls ‘Freedom from Interference’. Read how Read Article

Enjoying CERT C secure coding analysis with embedded compilers through Safety Checker The standalone version of TASKING Safety Checker can be used in various industries where IEC 61508 related regulations are in place, like ISO 26262 in automotive. In addition to its safety aware analysis it supports CERT C coding analysis independent from the tool chain that is in use. Altium always has been at the forefront of incorporating support for new standards in its embedded TASKING C compilers. It was one of the first to fully integrate Read Article

The Three Programming Essentials You Need to Know for AURIX™ Multi-Core TriCore™ With great architecture comes increased complexity, and if you're a developer about to embark on an AURIX™-based project then you’ll need to know these three programming essentials to get your development job done right the first time.

Follow the Data In Order to Assure Freedom from Interference The functional safety standard for road vehicles, ISO 26262, does not prohibit software with different Safety Integration Level (SIL) to interact and coexist in the same Electronic Control Unit (ECU), for as long as software elements of a lower safety level cannot interfere with elements at a higher safety level. This can be accomplished using software partitioning. The software is split up into parts of different Safety Integration Levels. Next Read Article

Corruption of Memory Content Safety standard ISO 26262 specifies that freedom from interference between software elements shall be ensured. The current safety mechanisms to address memory interferences have severe restrictions. Read on if you want to understand the weaknesses in today’s solutions to prevent corruption of memory content and illegal access to memory allocated to other software components. Freedom from Interference You are right if you consider taking enough Read Article
