misra (The Motor Industry Software Reliability Association 汽车工业软件可靠性联会) 是位于英国的一个跨国汽车工业协会，其成员包括了大部分欧美汽车生产商。其核心使命是为汽车工业提供服务和协助，帮助厂方开发安全的、高可靠性的嵌入式软件。这个组织最出名的成果是所谓的misra C Coding Standard，这一标准中包括了127条C语言编码标准，通常认为，如果能够完全遵守这些标准，则你的C代码是易读、可靠、可移植和易于维护的。最近很多嵌入式开发者都以misra C来衡量自己的编码风格，比如著名的uC/OS-II就得意地宣称自己99％遵守misra标准。
