* cmake: Update coding style to use lowercase commandsMartin Braun2018-11-141-31/+31
| | | | | | | | | | | | | | | | | Also updates our coding style file. Ancient CMake versions required upper-case commands. Later command names became case-insensitive. Now the preferred style is lower-case. Run the following shell code (with GNU compliant sed): cmake --help-command-list | grep -v "cmake version" | while read c; do echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g' done > convert.sed \ && git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' \ '*CMakeLists.txt' | xargs -0 gsed -i -f convert.sed && rm convert.sed (Make sure the backslashes don't get mangled!)
* host: lib: convert: Add CMake flag for NEON SIMDBrent Stapleton2018-09-121-1/+5
| | | | | | | Adding CMake flag to enable/disable NEON SIMD instructions. This is an addition to the previous checks (check for NEON headers and checking the size of pointers), so behavior is unchanged unless users specify that they do not want to use NEON instructions.
* uhd: Update license headersMartin Braun2018-02-1924-22/+46
| | | | | | | All copyright is now attributed to "Ettus Research, a National Instruments company". SPDX headers were also updated to latest version 3.0.

* converters: Remove log message in register_converterMartin Braun2017-09-291-1/+1
| | | | | Similar to b431866a5, this reduces logging in static initializer blocks. Those are prone to hang during DLL initialization.
* build: Enable SSSE3 sc12 converters by build switch onlyTom Tsou2017-07-261-0/+2
| | | | | | | | | | | | | | | The existence of SSSE3 intrinsic headers is not a sufficient condition that SSSE3 support is available, which may lead to 'illegal instruction' runtime failuire on some platforms. Major OS distributions (Ubuntu, Fedora, etc.) include x86_64 intrinsic headers, though the underlying architecture may or may not support the instruction set. Assuming SSE2 availability is safe as instructions are present on all x86_64 architectures for which instrinsic headers would be present. The same cannot be said for SSSE3. Issue: #1761
* convert: Add SSE implementation for sc12Tom Tsou2017-07-257-211/+719
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implementation uses SSSE3 intructions to perform 12-bit sample pack/unpack operations to/from standard 16 and 32 bit host values. Input/output shuffle orderings for a single 128-bit SSE register with 16-bit integers shown below. 16-bit interleaved I/Q --------------------------------------- | Q3 | I3 | Q2 | I2 | Q1 | I1 | Q0 | I0 | Input --------------------------------------- | 127 0 | 12-bit packed I/Q byteswapped ----------------------- | I0 | Q0 | I1 | 0 |-----------------------| | I1 | Q1 | I2 | Q2 | Output |-----------------------| | Q2 | I3 | Q3 | |-----------------------| | Unused | 3 ----------------------- 31 0 Fixes: #1740, #966 Related: #1739
* convert: Add sc12-sc16 convertersTom Tsou2017-07-182-24/+117
| | | | | | | | | | | | | | | | | Create missing sc12-sc16 and sc16-sc12 type converters. To avoid replicating the full sc12 converter class object, overload the converter calls with C++11 std::enable_if metafunctions. When used with std::is_floating and std::is_integral templates, this allow a single template interface with compile time function selection and static type checking. Note the below std::enable_if interface is confusing, but quite effective in this case. typename enable_if<is_floating_point<type>::value>::type* = NULL Fixes: #966 Related: #967, #1721

| | | | | | | | | | | | | | | | | | | | | | | | | | The sc16-sc16 wire to host type converter is effectively an I/Q swap or 16-bit byteswap for little and big endian cases respectively. This implmentation is a subset of fc32 and fc64 converters without the floating point portion and scaling. The resulting byte ordering is as follows: ----------------- | A | B | C | D | Wire ----------------- 0 1 2 3 ----------------- | C | D | A | B | Litte-endian ----------------- 0 1 2 3 ----------------- | B | A | D | C | Big-endian ----------------- 0 1 2 3 Signed-off-by: Tom Tsou <tom.tsou@ettus.com>

* convert: Limit sc12 converter buffer overwriteTom Tsou2015-01-141-12/+74
| | | | | | | | | | | | | | | | | | | | | This patch addresses issue #648 "B200: TX with SC12 format and MIMO". The observed MIMO header corruption was caused by overwriting the end of the packed 12-bit sample output buffer. The overwrite was due to the converter call always writing out 4 complex samples even if less than 4 samples were available. The extra samples would corrupt data with zero padding. Avoid the overwrite condition by only writing the minimum number of 32-bit lines necessary rather than the entire 12 byte struct.

* convert: Fix sc12 unpack shiftingTom Tsou2015-01-121-8/+8
| | | | | | | | | | | | Resolve issue #666 "B200: Rx signal distortion when using SC12". During 12-bit unpacking, OTW samples are shifted into the high order bits of the 16-bit intermediate values. The remaining 4-bits are not zeroed and contain bits from adjacent samples. Consequently, signal distortion becomes noticable with spurs and other random signal garbage when operating at low signal levels. Signed-off-by: Tom Tsou <tom@tsou.cc>
