Individual skill
multicore
Developing for multicore systems in Zephyr RTOS. Covers Symmetric Multiprocessing (SMP), Asymmetric Multiprocessing (AMP) with OpenAMP/RPMsg, inter-processor communication (IPC) patterns, and Linkable Extensions (LLEXT). Trigger when designing for SoCs with multiple homogeneous or heterogeneous cores.

# Zephyr Multicore Development
Leverage multiple CPU cores to increase performance, isolate critical tasks, and integrate heterogeneous systems.
## Core Workflows
### 1. SMP Configuration
Run the Zephyr kernel and your threads across multiple identical cores.
- **Reference**: **[smp_configuration.md](references/smp_configuration.md)**
- **Key Tools**: `CONFIG_SMP`, `k_spinlock`, Thread Affinity.
### 2. OpenAMP & RPMsg
Communicate between heterogeneous cores (e.g., A-series and M-series) using standard protocols.
- **Reference**: **[openamp_rpmsg.md](references/openamp_rpmsg.md)**
