Prasad Kaup Prasad.Kaup at radisys.comHello All,
We have executed profiling test of two versions of algorithm for decoding compressed bitmap of EPDAN.
>From the results , we see that performance is better in Tree based decoding (Version2 as given below )
Version 1: Bitmap based decoding as present in current master branch ( Function name osmo_t4_decode )
Version 2: Tree based decoding ( Function name decompress_crbb , as proposed in patch "Decompress the CRBB bitmap using tree based approach"<http://lists.osmocom.org/pipermail/osmocom-net-gprs/2016-March/000525.html> )
A sample bitmap taken from a real mobile log is used for the test.
Host execution: Time taken to decode (micro seconds)
Version 1: (Bitmap based decoding) : MIN -17 MAX -19 AVERAGE -17.9
Version 2 (tree based decoding): MIN -4 MAX -13 AVERAGE - 5.2
Target execution: Time taken to decode (micro seconds)
Version 1: (Bitmap based decoding) : MIN -277 MAX -583 AVERAGE - 353
Version 2 (tree based decoding): MIN -67 MAX -86 AVERAGE - 69.8
Regards
Prasad
