* gr-blocks: Add scaling option to Complex to/from ishort and icharghostop142020-02-2011-88/+73
| | | | | | | | | | | | | | | The existing block combinations of complex-to-ichar/ichar-to-complex and complex-to-ishort/ishort-to-complex was not exposing a scale factor to the UI (it was hard-coded at 1.0) which prevented the blocks from being used with voltage-based inputs and outputs, for example a -127 to 127 byte input would be mapped directly to the same value as a float. The same was true in reverse and there were notes in the code about FIX clipping. Adding the scale factor provides a mechanism for the user to appropriately fix the clipping and scale the conversion correctly. Additional documentation was added to the block yml to provide guidance to users on how to appropriately select the scale factor for their use case, and the default value was set to 1.0 for backward compatibility.
* blocks: support saving of all tags on tag debugIgor Freire2020-02-182-9/+34
| | | | | | | | | | For testing, it is often useful to check all tags ever received, rather than solely the tags from the last call to the Tag Debug's work function. This patch adds this option and a public method for activating it. This is more appropriate for controlled test environments, where the vector of tags is known not to grown indefinitely. Hence, the option is not exposed as a block parameter.
* Blocks: Add DC Spike Removal and IQ Swap Native Blocksghostop142020-02-159-0/+738
| | | | | | | | | | | | This block incorporates the OOT modules in correctiq that provide 3 different techniques to remove the DC spike inherent in IQ sampling. The first technique mirrors SDR GUI receivers with an IIR filter approach, the second provides a time-limited IIR approach where after a user-configurable number of seconds locks into a basic offset correction to eliminate the effect of the filter on the signal while maintaining the correction, and the last is manual I and Q configurable offsets. The Swap IQ block is a drop-in block to help correct for inverted spectrums and just swaps I<->Q.
* gr-digital: Improve Performance of Costas Loopghostop142020-02-141-22/+0
| | | | | | | | | | | | | This update is focused on improving the throughput of the Costas loop, however some changes are more global performance enhancements as this PR has evolved. Updates include an ENABLE_NATIVE added to CMake, which is off by default but enables native compiling (including FMA support) if desired; sincos was inlined in sincos.h and sincos.cc was removed from the appropriate CMake to improve sincos speed, some constants were added to math.h, inlined functions in costas loop and nco.h, used switch instead of function pointer (much faster), and used fast complex multiply to get around all the range checking in the standard complex.h complex multiply function on all builds.

* gr-blocks: use monotonic clock for throttleClayton Smith2020-02-042-17/+17
| | | | | | To ensure that the throttle block operates normally even if the system clock changes, I've switched it to use std::chrono::steady_clock, which is a monotonic clock.

* gr-blocks: VOLKize add_const_ff implementationGrant Cox2020-01-044-30/+30
| | | | | | | | | | | | - Use volk_32fc_x2_add_32fc to volk add constants to the input vector of the block - use volk::vector in add_const_ff_impl: Rather than using float* for variable length vector addition in volk, use volk::vector<float> for easier resizing. - Use scoped_lock when modifying private data members in add_const_ff_impl.cc. Remove getter functions for the d_k_copy vector. Cast with static_cast rather than typical cast. Use vector.data() rather than &vector[0].
* Replace many `const` variables with `constexpr`Thomas Habets2020-01-042-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | constexpr is like const but (for variables) guarantees evaluation at compile time (as opposed to runtime). Likely this change will do nothing on its own (though it could, since it gives the compiler more information). But it still has benefits. It allows programmer to know that initialization is not expensive (it was done at compile time), and reduces risk of a refactoring regressing the compiletimeness. Runtime initialization can be nonobvious in larger codebases. E.g.: struct S { static int foo(); }; const int bar = S::foo(); // Called and initialized at *runtime*. int S::foo() { return 10; } With constexpr: struct S { static constexpr int foo(); }; constexpr int bar = S::foo(); // Error: used before definition. constexpr int S::foo() { return 10; } Initializing at runtime is not just startup costs, but also can save memory since it'll end up in a R/O section of a binary and therefore doesn't need to be swapped out, but can be shared (in the mmap() sense of the word).

* Fix memset clearing non-trivial type gr_complex warnings in gcc-8Anders Kalør2019-08-221-2/+3
| | | | | | | | Using memset with gr_complex is not a problem since the underlying representation of gr_complex is guaranteed to be two floats in adjacent memory locations without padding or additional memory. Fixes #2743
* clang-tidy in gnuradio-runtime: use empty() instead of size()!=0Marcus Müller2019-08-2210-14/+14

* Use emplace_back(params) instead of push_back(type(params))Marcus Müller2019-08-228-51/+50
| | | | | | | | | | | | | | | | | | | This is C++11: you can convert std::vector<complextype> vec; vec.push_back(complextype(foo, bar, baz)); by std::vector<complextype> vec; vec.emplace_back(foo, bar, baz); which saves one unnecessary copy. This mostly happened in rpc code. The automated clang-tidy check failed miserably, so most of this was done by hand.

* blocks: random_pdu mask parameter fails under python3Josh Morman2019-07-172-4/+4
| | | | | | | | | | | | | | | | The use of chr() in the grc file for the mask creates an invalid input to the random_pdu make function 1) Change the inputs to unsigned char since this is a mask 2) Remove the chr() from the grc yml I'm not entirely sure what the purpose of the chr(mask) in the make function was, but it created invalid input Instead just pass the bitmask directly fixes #2557

* blocks: Modify File Source block to work with named pipes and devices.Ron Economos2019-03-312-33/+66

* cmake: Update to modern CMake usageAndrej Rode2019-03-041-78/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This includes using target based setting of includes and link libraries. This will transitively add the includes and linking flags to dependent targets. This is still a work in progress since only the dynamic libraries have been touched and not all of include_directories directives are gone yet. cmake: remove GR_INCLUDE_SUBDIRECTORY macro Previously this macro was used to inject subdirectories in the current CMake namespace. This is generally undesired and pollutes the current context. previously GNU Radio CMake had a non-default option ENABLE_STATIC_LIBS to build both, shared libraries and static libraries. This seems to be a construction taken over from autotools and serves no purpuose in CMake and complicates the library building. cmake: remove GR_LIBTOOL and la generation support This looks like it was primarily used to support projects using autotools, but comments state that the generated .la files aren't compatible with autotools anyway. cmake: Bump required CMake version to 3.8 UseSWIG cmake uses syntax which requires at least CMake 3.8 and is non-trivial to change
