Sakthivel Velumani 26b3fcca3b Remove SIMD operation for DMRS amplitude scaling 
There was concern that someone in the future might call the function
with the wrong inputs. So, based on the discussion on the MR below
https://gitlab.eurecom.fr/oai/openairinterface5g/-/merge_requests/2916#note_132506
the SIMD for multiplying DMRS vector with amplitude is removed and is
now done with plain C (no SIMD).

The execution time for the function dmrs_amp_mult() in this commit is
10x higher that the previous commit.

Sakthivel Velumani 393363e253 Refactor PUSCH RE mapping 
RE mapping time is reduced by 10x. Functions are made generic to be
later reused for PDSCH RE mapping at gNB.

Laurent THOMAS 18919576b7 rework PUCCH codec with c16_t type, rewrite large parts of functions to make readable code. Not fixed parts that are using SIMD. No change, the code is still same block by block (variable visibility narrowed, declaration can be shifted) 2024-01-04 10:21:15 +01:00

Raymond Knopp a7bc282302 First-level of support for new aarch64 machines 
Testing on Neoverse N1 (Ampere 3GHz). Tested only on a subset of phy-simulators.

- Changes:
- use SIMDE consistently
- adaptations of LDPC decoder generator for ARMv8 performance
- SIMDe modifications of Intel CRC to allow for aarch64 build.
  optimizations for 128-bit to improve performance of LDPC encode/decode
  on aarch64 (Neoverse 1)
- added BG2 files for 128-bit ldpc encoder (aarch64)
- testing on Xeon
- testing on x86
- minor changes to build/run on x86
- change in crc.h after returning to aarch64
- removed some warning in ldpc decoder generator for x86_64
- char
- Delete irrelevant constants
- Correctly declare variables
- Define stdbool for all architectures
- Remove definition of _MM_SHUFFLE and use SIMDE_MM_SHUFFLE
- Remove commented code
- Fix CMakeLists.txt
- Include SIMDE avx2 functions in tools_defs.h
