Worst-Case Execution Time (WCET) analysis for multicore systems
By Jay Thomas, Senior Director of Field Engineering, and Gerard Vink, Industry Specialist, TASKING This four-part article series explains how to assess Worst-Case Execution Time (WCET) in modern multicore embedded systems. In part 1, we established the conceptual foundation for understanding WCET by defining what interference and coupling are, how multicore hardware introduces hidden sources of timing variability, and the significant impact these can have on system execution.
Managing Compiler Errata
Managing Compiler Errata Although generally reliable, compilers are not without flaws. Issues typically emerge in corner cases and may not always affect the behavior of the compiled software. However, for software that must comply with functional safety standards, it is essential to demonstrate that the software is unaffected by these issues or to update the software accordingly. When software is developed by multiple parties and deployed across numerous devices, updates can be extremely costly.
Tasking: Fallgropar vid kvalificering av kompilatorbibliotek
Standarder för funktions- och cybersäkerhet betraktar kvalificering av verktyg och bibliotek som två oberoende uppgifter. Detta är oförenligt med perspektivet i standarden ISO C som ligger till grund för implementeringen av kompilatorn och dess bibliotek. Denna skillnad orsakar vissa utmaningar vid kvalificering av en kompilator med tillhörande kompileringsbibliotek.
Pitfalls When Qualifying Compiler Libraries
Article By : Gerard Vink, TASKING This article briefly outlines the ISO 26262 tool and library qualification requirements, describes the composition of a C compiler toolset including the dependencies between the components, and explains which qualification criteria apply to the various components.
Compiler Tool Qualification for Functional Safety and Cybersecurity
Article By : Gerard Vink, TASKING While safety processes are established and mature, automotive trends including digitalization, connectivity, and highly automated vehicles require the need for comprehensive cybersecurity processes. The automotive industry is characterized by three major trends: digitalization, connectivity, and highly automated vehicles. While safety processes are established and mature, each of these three trends requires the need for comprehensive cybersecurity processes.
