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
