C and C++ programmers very often allocate and de-allocate memory on the heap without the proper understanding on how these low-level facilities work and what happens underneath. But these memory related problems becomes a great concern in the systems with shortage of almost all the resources including memory, like embedded real-time systems. This dynamic behavior tends to be non-deterministic and the failure is hard to contain. Similarly memory allocation failure on such systems can be fatal. Unlike a desktop application, most embedded systems do not have the opportunity to pop up a dialog and discuss options with the user. Often, resetting is the only option, which is unattractive. This technical paper attempts to discuss the strategies to achieve clean code and appropriate memory management.
Wind River rolled out the Wind River VxWorks Cert Platform, which is a combination of the VxWorks DO-178B and IEC 61508 safety critical platforms. The Wind River VxWorks Cert Platform supports C++ and real-time processes (RTP). VxWorks Cert is ideal for safety critical applications that must be certified to the stringent requirements of RTCA DO-178B and EUROCAE ED-12B (Software Considerations in Airborne Systems and Equipment Certification) and IEC 61508 and other related software standards. Wind River VxWorks Cert Platform is available now worldwide. The VxWorks DO-178B Platform and VxWorks 61508 Platform will no longer be availabe as separate, standalone platforms.
