Express Logic Announces ThreadX® MISRA Compliance

ThreadX RTOS compliant with MISRA C:2004 and MISRA-C:2012 ANSI C programming guidelines

San Diego, CA - Express Logic, Inc., the worldwide leader in royalty-free real-time operating systems (RTOSes), today announced that its popular ThreadX® RTOS is compliant with all required and mandatory rules of MISRA C:2004 and MISRA-C:2012.

MISRA C, a set of programming guidelines developed by the Motor Industry Software Reliability Association (MISRA), promotes safety, reliability, ease of maintenance, and portability for safety-critical systems coded using the ANSI C programming language. Although the original MISRA-C guidelines targeted automotive applications, MISRA-C is now widely recognized as a leading guideline for C programming in the development of a broad range of safety-critical applications in aerospace, telecom, medical, defense, railway, and other sectors.

MISRA: Essential Guidelines for Safety-Critical Product Development

Software failure and, more important, direct programming errors have cost companies millions of dollars in lost sales, damages, and litigation and, in some cases, have resulted in human fatalities. Consequently, manufacturers have implemented increasingly rigorous practices, guidelines, and certification standards to decrease risk, increase and measure product reliability, and improve product quality.

“MISRA-C is one of the most crucial guidelines for prevention of errors that manufacturers can implement,” said William E. Lamie, CEO of Express Logic, Inc. “Through its compliance with MISRA-C, Express Logic’s ThreadX plays an essential role in safety-critical product development.”

Express Logic verified ThreadX MISRA-C compliance for both the 2004 and 2012 standards using IAR Embedded Workbench C-STAT analysis tool. Lamie added, “The seamless integration of C-STAT, a powerful analysis tool, made our MISRA-C complicance analysis much easier.”

“We are proud that Express Logic has chosen to work with IAR Embedded Workbench and C-STAT to verify MISRA C compliance for ThreadX,” commented Anders Holmberg, Product Manager Analysis Tools, IAR Systems. “C-STAT ensures code quality and shows compliance with industry standards. Thanks to its complete integration in the development tools, companies find it easy to work with, gain code quality checks in the daily work of each developer, and are able to take full control of their development through efficient, adaptable workflows that deliver dependable products.”
