There can be multiple partitions in an AI Engine array. Each partition contains independent graphs.
The xclbin file generated by the v++ packager includes the metadata for all partitions.
For information about the v++ building flow, see
Compiling AI Engine Graph for Independent Partitions.
A handle to a graph in a partition can be retrieved from the device after
loading the xclbin. You can use this handle to
control the graph by prefixing the graph name with the partition name in the xrt::graph(device,uuid,"pr0_gr") API. Following is
example code used to control the pr0 and pr1 partitions:
// Open xclbin
auto device = xrt::device(0); //device index=0
auto uuid = device.load_xclbin(xclbinFilename);
//Create handle for graph "gr" in partition "pr0"
auto ghdl1=xrt::graph(device,uuid,"pr0_gr");
ghdl1.run(iterations);
//Create handle for graph "gr" in partition "pr1"
auto ghdl2=xrt::graph(device,uuid,"pr1_gr");
ghdl2.run(iterations);
ghdl1.wait();
ghdl2.wait();To reload AI Engine partitions on hardware refer to Runtime Control and Reload of AI Engine Partitions.
