Change subject: codec: add osmo_hr_sid_classify() ...................................................................... Patch Set 2: (2 comments) File src/codec/hr_sid_class.c: https://gerrit.osmocom.org/c/libosmocore/+/37558/comment/9781f8e8_314e66a0 PS2, Line 35: for (; byte; byte >>= 1) { This is absolutely fine for not so hot code paths, but if this is to be done for each byte of each RTP frame, I would recommend using a look-up table here. It can contain bit count for all 4-bit values, so then you could do: ``` return table[byte >> 4] + table[byte & 0x0f]. ``` https://gerrit.osmocom.org/c/libosmocore/+/37558/comment/91be866d_6ca1e1ec PS2, Line 144: class1_ones = sid_field_ones - class2_ones; I am wondering if, in theory, `class2_ones` can be greater than `sid_field_ones`? We'll end up with a huge number in this case. -- To view, visit https://gerrit.osmocom.org/c/libosmocore/+/37558?usp=email To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: libosmocore Gerrit-Branch: master Gerrit-Change-Id: I5f4eb65379646125b966cf182775b6e9348900bd Gerrit-Change-Number: 37558 Gerrit-PatchSet: 2 Gerrit-Owner: falconia <[email protected]> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: laforge <[email protected]> Gerrit-CC: fixeria <[email protected]> Gerrit-Attention: falconia <[email protected]> Gerrit-Comment-Date: Mon, 29 Jul 2024 07:58:30 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Gerrit-MessageType: comment
