 Any idea how to calculate it ? 
 
 eg .. 
 start = timer_start; 
 algo(); 
 end =timer_end; 
 
 cycle = start - end; 
 
 If anyone have any code snippet. It would be great help. </description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: Cycle count on MPS3 board for cortexR52x2</title><link>https://community.arm.com/thread/168584?ContentTypeID=1</link><pubDate>Wed, 11 Nov 2020 01:34:28 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:48c330bd-91bf-4cc0-8ec7-072035e048cd</guid><dc:creator>Ronan Synnott</dc:creator><description>&lt;p&gt;Hi Mohanish,&lt;/p&gt;
&lt;p&gt;Do you have access to Arm Development Studio. This includes a PMU_AArch64 example which should show you how to do this.&lt;/p&gt;
&lt;p&gt;You can get a 30 day evaluation version of the tool if necessary.&lt;/p&gt;

&lt;p&gt;Regards&lt;/p&gt;
