Immunity-aware programming

When writing firmware for an embedded system, immunity-aware programming refers to programming techniques which improve the tolerance of transient errors in the program counter or other modules of a program that would otherwise lead to failure. Transient errors are typically caused by single event upsets, insufficient power, or by strong electromagnetic signals transmitted by some other ""source"" device.Immunity-aware programming is an example of defensive programming and EMC-aware programming. Although most of these techniques apply to the software in the ""victim"" device to make it more reliable, a few of these techniques apply to software in the ""source"" device to make it emit less unwanted noise.
