FreeRTOS-Kernel conforms to [MISRA C:2012](https://www.misra.org.uk/misra-c)
|

guidelines, with the deviations listed below. Compliance is checked with
|

Coverity static analysis. Since the FreeRTOS kernel is designed for
|
||||
small-embedded devices, it needs to have a very small memory footprint and
|
||||
has to be efficient. To achieve that and to increase the performance, it
|
||||
deviates from some MISRA rules. The specific deviations, suppressed inline,
|

are listed below.
