This is going to be a fascinating talk. The overheads of AUTOSAR aren’t apparent until someone - or something - takes a close look. Only then can the impact of a specific configuration be seen. The insights from this can potentially lead to huge savings in RAM and CPU time, and make the difference between a system fitting into the hardware or not.

Automotive world Adaptive AUTOSAR relies (in 2017) on the C++14 language standard. The choice of the language standard version was a selection between “not too old” and “not too new.” …but now “not too new” it doesn't make sense anymore, because with the release of the C++23 the currently still used C++14 version is “too old” and is not matching/using the latest hardware performance (without considering the bugs of C++14 fixed in the C++17) As somebody says 😉: “… this is simply a very good example of how old school car industry is simply having too slow clock cycle compared to SW industry.  They fear steady and continuous increments and are stuck to older solutions” How much we still have to wait (at list for C++17 integration in Adaptive AUTOSAR), the release of C++25 or C++28 ☺️

For years, software development in mainstream computing thrived on Moore’s law without major changes. However, as clock speeds plateaued, chipmakers shifted to hyperthreading and multi-core designs for better performance. This trend now affects the automotive industry, with modern microcontrollers and SoCs embracing multi-core architectures. To capitalize on these advancements, automotive software, including AUTOSAR architectures, must evolve to adapt to these changes.

WHY AUTOSAR FAILS 🚨 Offensive headline? Well, many #automotive software projects struggle for the same reason: an unfortunate #AUTOSAR configuration. A very inefficient system and system #overloads are the results. Peter Gliwa will present common pitfalls as well as solutions at the 15th AUTOSAR Open Conference in Tokyo next week on 12th June. What are your experiences with AUTOSAR performance? Let us know and add a comment below ⬇ #T1 #timinganalysis

#Automotive #Classic #AUTOSAR #Memorystack: Description of new module "Memory Access" in classic AUTOSAR: ----------------------------------------------------------------------------------------- The Memory Access #MemAcc Module was introduced in AUTOSAR Release 21.11 and it provides access to different memory technology devices such as flash, EEPROM, RAM. The Memory Access module and Memory drivers are located in the same layer of the AUTOSAR architecture as Fls and Eep Driver but split these modules into a hardware independent part (MemAcc) and a hardware dependent part (Mem). One of the important use-cases to use the #MemAcc module, is the Software Update which requires coordination of the memory access between the normal AUTOSAR stack and the other part of the Software Update #OTA. The #MemAcc module has interfaces towards the Flash EEPROM Emulation #Fee, the EEPROM Abstraction #Ea, Bulk Nv Data Manager #BndM, Memory Drivers e.g. #Fls, and #OTA software update.

Our friends over at LHP Engineering Solutions have an incredible blog post on "What Does the Foreseeable Future of an AUTOSAR Engineer Look Like?." To address this question, understanding the history and the business case for AUTomotive Open System ARchitecture or AUTOSAR is important. This blog post will address this question while also showing the parallel to another large shift that occurred previously in embedded software development. Check it out now: https://hubs.li/Q02v4_sg0 Let us know what you think!

This is a really great talk. If you're limited in time, whizz to 8:00 minutes and see examples of CPU overheads in three completely different ECUs. The AUTOSAR RTE really can gobble up a lot of the CPU cake 🍰 Interrupt suspend/copy/resume being done 340,000 times per second is just crazy. And $170m in extra silicon costs for a faster CPU just to run all these interrupt suspend/resume locks is beyond crazy.
