This example shows you how to construct a graph with packet switching capability. In the first section, Construct Graph with Packet Switching Capability, the example graph features:
Four parallel AI Engine kernels, with all four kernels sharing the same input and output ports to the PL.
AI Engine kernels using window interfaces, which means they are agnostic about how data is communicated to the PL.
This section introduces two new templated node classes,
pktmerge<n>, to construct the graph. These classes switch the packet to the correct destination and construct the packet with the corresponding packet IDs, respectively.
Then this example:
Introduces the Packet Format and how to Prepare Data and Run AI Engine Simulator.
Introduces a system design that includes Example PL Kernels for Packet Switching. In the example PL kernels, you can see how a packet is constructed and how the packet ID generated by the AI Engine compiler is used.
Shows PS code for the system design in Example PS code for Packet Switching.
Shows how to Run Hardware Emulation and Hardware flows.
