A core is a single, independent instruction execution pipeline within a CPU. It contains an ALU, registers and an instruction decoder, which makes it roughly equivalent to a whole CPU.

Modern processors pack from 4 to more than 128 cores onto one die, each with private L1 and L2 caches and a shared L3.

Multi-core scaling requires careful synchronization through mutex primitives to avoid data races.

ARM big.LITTLE pairs high-performance Cortex-A cores with efficient ones for power-aware scheduling.
