struct QnnDspGraph_OptimizationOption_t
#include <QnnDspGraph.h>

Struct describing the set of optimization types and the values associated with each optimization type.

Below is the Map between QnnDspGraph_OptimizationType_t and allowable values:

#

OptimizationType option

Allowable values

1

QNN_DSP_GRAPH_OPTIMIZATION_TYPE_SCHEDULE_THRESHOLD

Reserved

2

QNN_DSP_GRAPH_OPTIMIZATION_TYPE_FINALIZE_RETRIES

Reserved

3

QNN_DSP_GRAPH_OPTIMIZATION_TYPE_FINALIZE_OPTIMIZATION_FLAG

Defines the optimization strategy used by the HTP backend

1 = Faster preparation time, less optimal graph

2 = More optimal graph but may take longer to prepare

QnnDspGraph_OptimizationType_t type
float floatValue
struct QnnDspGraph_CustomConfig_t
#include <QnnDspGraph.h>

Structure describing the set of configurations supported by graph. Objects of this type are to be referenced through QnnGraph_CustomConfig_t.

The struct has two fields - option and a union of corresponding config values Based on the option corresponding item in the union can be used to specify config.

Below is the Map between QnnDspGraph_ConfigOption_t and config value
