Sorry, it was my fault. I've only looked generic implementation, without
pay attention that is the operator * is also defined for complex.
Have a good day

Is it a bug or a feature?

Hi,
now I need to install also the UHD module of gnuradio(before I've used only
RTL). Is possible to install this module without reinstall the entire
gnuradio?
I've tried the easiest apprach, mkdir/cmake/make.. in gnuradio/gr-uhd, but
it doesn't work.
Thanks,
marco

require only the previous output,I think what the implementaion would be
not difficult: thanks to the expansion of recurrence expression, is
"sufficient" something like a parallel sum prefix.

Hi,
I've a question about thread management..I like the fact that scheduler can
launch blocks in different threads, but I'd like to execute some blocks
inside the same thread(CUDA require to perform all operations from a single
thread)..for the moment I'm using GR_SCHEDULED=STS,but it blocks at all
Thank you for your replies!! I really appreciate them.
If you want to give a look about my porting,here is possible to see

For the bug, wouldn't be sufficient to substiture the above code
// Find the magnitude squared of the correlation
std::vector corr_mag(noutput_items);
volk_32fc_magnitude_squared_32f(&corr_mag[0], corr, noutput_items);
with:
std::vector corr_mag(noutput_items+1);
volk_32
_mag[i+1])
i++;
is not possible that the variable i will go outside the array corr_mag?I
know that is necessary a strange pattern in order to have the last item
greater than the previous..

Hi,
for my thesis I'm making "porting" of gnuradio blocks over CUDA..
For the moment,I've bring basick blocks,FIR filter,FFT,an FM receiver(not
so good due to latency) and I'm working with ofdm..I still need to
implement IIR filter
Which other blocks do you think that could be nice(useful,get

Tahnk you very much for your reply.
I've tried different time with templates,but I was not able to obtain a
result(cmake and make finish errors,but I suppose that swig crash,because
python scripts are not able to access to any block written in C,also blocks
without template)..
At the end I've solv
Looking inside gnuradio,I've found blocks like divide_XX where relative
files have an extension .t (like divide_XX_impl.cc.t )..in this way,is
possible to manage different types for the same block.
How is posssible to create blocks like them? is necessary to use particular
parameters in gr_modtools
Marcus, thank you very much for your deep answer.
Your proposal about the usage of
your_block::detail()->input(0)->buffer()->link seem very interesting, so I
shoulld evaluate if use this mechanism or only some memory allocation

Looking better about implementation of blocks like fft,fir,etc a question
rise in my brain.
Why in blocks with selectable input/output data type there are C++ multiple

with _cc,_ff,etc), instead of use template(and eventual

In order to create blocks using the standard way(cmake/make/install) with
Cuda,I've modified the CMakeList in /lib as shown before. My block is
created using gr_modtool and the language is c++.
The fact is that "make test" works well,while in GnuRadio interface give me

Hi all,
I'd like to establish a bidirectional communication between two attached
blocks, without asking the user to write code like msg_connect(). One way
could be: the upstream block generate an id like
ID=typeBlock+pseudorandomNumber
and send it to the next block using a tag.

I'm playing with CUDA and GNURadio. For the moment I've used separatly nvcc
in order to compile device code: I've tried different tutorials which

result.
Can someone explain me how to modify Cmake's file of a basic GNU
