SMP or AMP
Concurrent execution of separate task sets.

AMP Key facts
AMP: Asymmetric Multiprocessing
Heterogeneous System Different core purposes (CPU + DSP) Different core types (Application + Low Power) Same core architecture (Dual/Quad – Core CPUs) Multiple chips of same/different type
Each core has its designated task set=> More than one operating system
Cores do NOT share code and data

SMP Key facts
SMP: Symmetric Multiprocessing
Homogeneous System All cores of the same architecture
All cores share a common task set
One operating system manages all cores
The operating system assigns tasks dynamically to cores
Cores share code, data and peripherals (UMA: Uniform Memory Access)

Static – SMP vs. Dynamic – SMP
SMP: Symmetric Multiprocessing
Homogeneous System All cores of the same architecture
One operating system manages all cores
Common code, data memories
BUTStatic - SMP
Static Task to Core assignment
Tasks use non-shared/private peripherals and/or memories
Dynamic - SMP
Dynamic Task to Core assignment
Tasks use only shared peripherals and memories
