TIOVX Framework Overhead Benchmark

TIOVX Framework Overhead Benchmark

Average values are reported after performing 100 iterations on each target. Framework overhead is calculated by subtracting the execution time of a single node from the total execution time of its graph. Execution time is measured by querying each graph and node after calling vxProcessGraph.

Core Target Average Graph Performance (msec) Average Node Performance (msec) Average Overhead [Graph - Node] (msec) Maximum Overhead (msec) Minimum Overhead (msec)
