<p class="MsoNormal">Hello All,<o:p></o:p></p>
<p class="MsoNormal"> We have executed profiling test of two versions of algorithm for decoding compressed bitmap of EPDAN.<o:p></o:p></p>
<p class="MsoNormal">From the results , we see that performance is better in Tree based decoding (Version2 as given below )<o:p></o:p></p>
<p class="MsoNormal">Version 1: Bitmap based decoding as present in current master branch ( Function name osmo_t4_decode )<o:p></o:p></p>
<p class="MsoNormal">Version 2: Tree based decoding ( Function name decompress_crbb , as proposed in patch “<a href="http://lists.osmocom.org/pipermail/osmocom-net-gprs/2016-March/000525.html"><span style="color:windowtext;text-decoration:none">Decompress
the CRBB bitmap using tree based approach”</span></a> )<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">A sample bitmap taken from a real mobile log is used for the test.<o:p></o:p></p>
<p class="MsoNormal"><o:p></o:p></p>
<p class="MsoNormal">Host execution: Time taken to decode (micro seconds)<o:p></o:p></p>
<p class="MsoNormal">Version 1: (Bitmap based decoding) : MIN -17 MAX -19 AVERAGE -17.9
<o:p></o:p></p>
<p class="MsoNormal">Version 2 (tree based decoding): MIN -4 MAX -13 AVERAGE - 5.2
