Compare and Swap Pair of words or doublewords in memory reads a pair of 32-bit words or 64-bit doublewords from memory, and compares them against the values held in the first pair of registers. If the comparison is equal, the values in the second pair of registers are written to memory.

Lots of variation in atomic instructions, consistency models arm: Relaxed Consistency Model, RISC E.g., atomic compare and swap: CAS (mem, old, new).In computer science, compare-and-swap (CAS) is an atomic instruction used in multithreading to achieve synchronization. It compares the contents of a memory
MX7D: atomic compare and swap instructions don’t work with cache MX or NXP BSP feature so maybe in the ARM community this will be
Atomic Operations in Hardware Today we’ll look at instruction support for synchronization. Common primitive: compare-and-swap (old, new, addr).
