12.3.5. Measuring Performance in the Hostless DDR-Free Design Example

The system console script allows you to measure the following types of performance:

  • Core IP Performance

    Specifying the --core_ip_performance operation mode option sets the --num_inferences option to 1 and stages the input into the input_streamer before starting the inference.

    This operation mode measures the latency of 1 inference through the IP without the time to fill the input streamer FIFO.

  • System Throughput

    Specifying the --ip_performance operation mode sets the --num_inferences option to 32 and measures the throughput of the graph. This mode only saves the last output since offloading the output after every inference could limit the performances.

    This operation mode measures the throughput of the whole system including input streamer and output streamer.
