Is that a general question or is it targeted to a specific architecture
? (like x86 or arm or ... even SoC)
The notion of process/tasks is something that is alien to a CPU/core. It
runs the next instruction or process some interruptions (by stacking the
current state and performing a change of PC).
The process/task concept is an illusion created by the scheduling code
of the OS.
