* 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. Samples 32-bit lines 1 1 2 2 3 3 4 3 Signed-off-by: Tom Tsou <tom@tsou.cc>
* 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>

* Restoring compatibility with CMake 2.6Nicholas Corgan2014-08-141-1/+1
| | | | | * The UNSET command didn't exist back then, but using SET with no value does the same thing * CMake 2.6 doesn't like nested parantheses in IF statements, so tweak IF/ELSE statements

| * convert: fixed sc8 convert issue w/ undefined behaviourJosh Blum2012-05-081-16/+24
| | | | | | | | | | | | | | Its important to use a signed cast when converting float to int. Then assign that signed int to an unsigned type of the same width. Its undefined behaviour when converting a negative float to an unsigned int.
* | convert: added prio param to get converterJosh Blum2012-04-271-20/+23
|/ | | | We can now test generic conversion implementations against SIMD (for example)
* convert: give SIMD conversions prio over tableJosh Blum2012-04-161-2/+2
| | | | | | | | given performance benchmarks involving the converter, when the driver is also doing other things sc8 conversions will still involve tables since no SIMD implementations exist yet
* uhd: fix sc16 to sc8 conversion tableJosh Blum2012-02-291-12/+12
| | | | | | | 1) this was registered as the sc8 to sc16 converter, probably messed that up as well 2) the cast to index was wrong, now unit test passes
