Atomics
Explore the role of atomics in the C++ memory model, focusing on their types and how atomic operations ensure proper synchronization and ordering in concurrent programming. Understand memory orderings like acquire, release, and relaxed to better handle multithreading in embedded systems.

Atomics are the base of the C++ memory model. By default, the strong version of the memory model is applied to atomics. Therefore, it is important to understand the features of the strong memory model and their relation to atomics.
Atomic operations on atomics define the synchronization and ordering constraints.
Kinds of Atomic Operations
There are three different kinds of atomic operations:
- Read operation:
memory_order_acquireandmemory_order_consume - Write operation:
memory_order_release - Read-modify-write operation:
memory_order_acq_rel
