The following graph control API shows how to run the graph infinitely.
#include "project.h"
simpleGraph mygraph;
int main(void) {
mygraph.init(); // load the graph
mygraph.run(); // start the graph and return to main
......
return 0;
}The API declares a graph object mygraph
using a pre-defined graph class called simpleGraph.
Then, in the main application, this graph object
initializes and
runs.
The
init() method loads the graph to the AI Engine array at prespecified AI Engine tiles. This includes loading the ELF binaries
for each AI Engine, configuring the stream
switches for routing, and configuring the DMAs for I/O. It leaves the processors in a
disabled state.
The run() method starts the graph
execution by enabling the processors. This graph runs forever because the number of
iterations to be run is not provided to the run()
method.
graph::run() without an argument runs
the AI Engine kernels for a
previously specified number of iterations (which is infinity by default if the graph is
run without any arguments). If the graph is run with a finite number of iterations, for
example, mygraph.run(3);mygraph.run() the second run
call also runs for three iterations. Use graph::run(-1) to run the graph infinitely regardless of the previous run
iteration setting.
