PMU Profiling Utlity Example

The example demonstrates several PMU profiling facilities offered by neuralSPOT: * Measuring time using the Tick Timer * Basic PMU Counter Collection * Full PMU (performance management unit) collection (CortexM55-based platforms)

The example uses one neuralSPOT's MFCC feature extractor as an example algorithm to be profiled.

Results

The SWO output can be divided into 3 sections: 1. Time measured for a single run 2. PMU counters (single run showing 4 PMU event counters) 3. Full PMU counters collected via repeated runs
