# Profiler utility app

profilerUtilityApp is an on-device application that provides the following services:

| Service | Description |
| --- | --- |
| Benchmark | NSP benchmarking is a feature in the ProfilerUtilityApp for studying the performance of common image processing APIs on DSP |
| Clocks | This service is used to set the Q6 core clock and bus clocks of desired Q6 processor. |

## Benchmark service

Various standard benchmarking algorithms can be run on the NSP to benchmark processor performance.
Options can be set for each algorithm, such as defining the height and width of the images on which the benchmarking algorithm’s calculations will occur.
You can get a list of the supported algorithms and parameters using the following command:

profilerUtilityApp --dsp –benchmark –help

## Clock service

The clocks feature enables setting, limiting, and removing the Q6 clocks of a Q6 processor. The clock value may not be set to the exact value; rather it is set to the nearest supported clock value.

| Clock functionality | Description | Sample command |
| --- | --- | --- |
| Set | Sets the Q6 clock to a desired frequency for the a particular Q6 processor. | `profilerUtilityApp --dsp --clocks set --coreClock 200 --q6 nsp` |
| Limit | Limits the maximum clock frequency of the Q6 processor at which it can work for the performance requirement or safety reason. | `profilerUtilityApp --dsp --clocks limit --coreClock 1000` |
| Remove | Resets all the clock settings to the default values. | `profilerUtilityApp --dsp --clocks remove` |

**Examples**

- Set close

> 
> 
> profilerUtilityApp --dsp --clocks set --cengClock 700
>         Copy to clipboard
- Remove clock

> 
> profilerUtilityApp --dsp --clocks remove
