Hello GNU Radio Community and friends of UHD, UHD 4.1.0.5 has been released! Apart from some minor enhancements and bugfixes (see below for the complete changelog), UHD 4.1.0.5 adds support for the NI Ettus USRP X410 Rev G, which uses a different CPLD on the motherboard than previous revisions. P

True, but with Pybind11, we at least get direct python->C++ bindings which *can* allow for in-place modification of appropriately typed numpy arrays. For other languages, the C layer should be pretty much a zero-overhead redirection (or so I hope), just like it's theoretically useful right now.

If nothing else I think there is a lot of value in adding c++ wrappers to volk. I don't have a strong opinion on an underlying base of c or c++, but would like for it to be easier to use in c++. A common approach with other c libraries like zeromq is to make a header only c++ wrapper. This would ta

I like the idea. It will make it difficult to use volk with other language's FFI though. --Albin On Tue, Dec 21, 2021, 12:27 Marcus Müller wrote: > Hi Johannes, > > I, for one, like it :) Especially since I honestly find void > volk_32fc_x2_s32fc_multiply_conjugate_add_32fc to be a teeny tiny b

Hi Johannes, First of all thanks for the quick response and time with my problem. I've made a text file with all specifications of my OFDM example that can be found in the attachments of this mail. Thanks again with your help and anything more just let me know. Best regards, Pedro Viegas

Hi Johannes, I, for one, like it :) Especially since I honestly find void volk_32fc_x2_s32fc_multiply_conjugate_add_32fc to be a teeny tiny bit clunky and would rather call a type-safe, overloaded function in a volk namespace called multiply_conjugate_add. Re: RFC: can we have something like

VOLK C++ core

2021-12-21 Thread Johannes Demel
Hi everyone, today I'd like to propose an idea for the future of VOLK. Currently, VOLK is a C library with a C++ interface and tooling that is written in C++. I propose to make VOLK a C++ library. Similar to e.g. UHD, we can add a C interface if the need arises. This email serves as a reque
