| MISRA C | ||||||||||
| MISRA C is a formal set of guidelines for programming in
the C language. These guidelines, published by the Motor
Industry Software Reliability Association (MISRA), identify
aspects of the C language that should be avoided due to
their ambiguity and susceptibility to common
programming mistakes. Each guideline is documented with
background reasoning, examples, and justification. By following this well-researched set of rules and documented set of safe programming practices, the risk of writing bad or error-prone code can be significantly reduced. As a result, a better, safer system can be developed and the time lost finding bugs can be reduced. |

The cost of flexibility The C language is probably the most widely-used highlevel language in embedded systems today. This is largely due to its incredible flexibility: C is available for a huge range of systems and can implement virtually any type of software application. This flexibility comes at a cost however. Ambiguities in the C language, along with certain syntaxes, consistently trip up even the best programmers and result in bugs. For software developers, this means a large amount of unexpected time spent finding bugs. For managers, this often means the single largest risk to their project. Achieving productivity While MISRA C is a set of guidelines for a software developer, it is not a specification for a compiler. Therefore, developers can painstakingly enforce these rules themselves through inspection. But to realize true productivity, these manual steps must be automated and consistently enforced. The MULTI Integrated Development Environment offers this exact capability. |

| Extensive coverage Green Hills Software supports MISRA C in standard release of all 32- and 64-bit products, including MULTI for ARM, V800, PowerPC, MIPS, x86, StarCore, and others. Green Hills is also uniquely qualified to support the largest number of MISRA C rules for embedded development through its Optimizing Compilers and Advanced Run-time Error Detection. Green Hills supports MISRA-C:1998 as well as the latest MISRA specification: MISRA-C:2004. |

graphical environment for embedded target development. MULTI features
With MULTI, developers can select exactly which MISRA C rule to enforce. The selection can be done graphically or from the command line. At compile time, violations of MISRA C rules are reported. Violations that can only be detected at run-time are automatically detected and reported by Green Hills advanced run-time error detection. |

| Across industries | ||||||||||
| MISRA C has been developed to address the critical need for reliable systems in the automotive industry. It achieves this by formally identifying good programming practices and types of C code susceptible to error. Implementing these guidelines has a direct effect on the reliability of a final system. Regardless of the industry or application, the ability to consistently detect and reduce errors will significantly reduce time spent debugging. |
