== Introduction ==
This application note describes how to build the software components required to set up asymmetric multi-processing (AMP for short) configuration required to run Linux OS on the first Cortex-A9 core (also denoted as core #0) and FreeRTOS on the second Cortex-A9 core (also denoted as core #1) of the Zynq SOC.
Asymmetric Multiprocessing (AMP) allows a multiprocessor/multicore system to run multiple Operating Systems (OS) that are independent of each other. In other words, each CPU has its own private memory space, which contains the OS and the applications that are to run on that CPU. In addition, there can be some shared memory space that is used for multiprocessor communication. This is contrasted with Symmetric Multiprocessing (SMP), in which one OS runs on multiple CPUs using a public shared memory space. Thanks to AMP, developers can use open-source Linux and FreeRTOS operating systems and the RPMsg Inter Processor Communication (IPC) framework between the Zynq's two high-performance ARM® Cortex™-A9 processors to quickly implement applications that need to deliver deterministic, real-time responsiveness for markets such as automotive, industrial and others with similar requirements.
