Usage
You need to specify a minimum speedup for a region to be estimated as recommended for offloading in a custom TOML configuration file with a
min_required_speed_up
parameter. By default, the minimum speedup is set to 1.
  1. Create a custom configuration file with
    min_required_speed_up
    set to 2.
  2. Run Survey Analysis.
  3. Run Trip Counts and FLOP analyses of the Characterization stage.
  4. Model your application performance on a target device with a minimum speedup set to 2.
