The Libmetal AMP Demonstration Application describes how to open and access devices, namely shared memory and interrupts.

Xilinx ® Vitis and PetaLinux tools include a libmetal demo to demonstrate how to use the libmetal library to build simple interprocessor communication between APU (Application Processing Unit) and RPU (Real-Time Processor) on a Zynq UltraScale+ MPSoC platform.

The example uses the following resources for the inter-processor communication:

DDR (Double Data Rate)

IPI (Inter Processor Interrupts) for notification.

Triple Timer Counter for measurement of latency and throughput demonstrations.

The next section describes how to build the libmetal example with Xilinx® Vitis and PetaLinux tools.

The Libmetal AMP Demonstration includes:

Shared memory.

Shared memory with atomics.

IPI with shared memory.

IPI latency measurement.

Shared memory latency measurement.

Shared memory throughput measurement.
