I am familiar with the FPGA n also with the MATLAB but didn't have any idea about how to convert the coding. After searching for the respective topic i came to know that there is a simulink HDL coder in MATLAB which can do this task. The problem is that i don't have much information about Simulink HDL Coder. So please if anyone can tell me from where to start and can suggest any literature regarding this will be of great help to me. > > > Thanks in Advance > Regards > Hamid Hello hamid, I would like to know how you went about your design using MATLAB HDL coder.

Dear friends, I have a Matlab code to process a pure analog signal 'u'. Now I want to implement it in Simulink and I want to use it in 'Embedded Matlab fun block' so i need to transform 'Matlab code' to 'Embedded Matlab fun code' to perform the task. The Matlab code is as follows: %%%%%%%%%%%%%%%%%%%%% u_abs = abs(u); major_th = 1.5e-1; minor_th = 1.8e-2; major_peak_value = []; minor_peak_value = []; pos = 1; pos_max = 1; while ~isempty(pos) [m pos_max(end+1)] = max( u_abs( pos : pos + 10) ); pos_max(end) = pos_max(end) + pos - 1; if m > major_th major_peak_value(end+1) = m; else minor_peak_value(end+1) = m; end % exit the peak pos = find(u_abs(pos:end) < minor_th, 1 , 'first') + pos-1; % Find the beginning of the next peak pos = find(u_abs(pos:end) > minor_th, 1 , 'first') + pos-1; end pos_max(2) = []; plot(u); hold on; plot(pos_max,u(pos_max),'ro'); %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% I think i don't need this plot command as I will see the result in the scope directly. Any suggestion will be very useful. Thanking you!

Hello, I have had the dubious distinction of inheriting tons of matlab code from a former student (and he is gone, of course) and am trying to figure out what it is doing. There is a particular code segment that has me stumped and I was wondering if someone can help me figure out what it actually does: So, I have an array P that holds the joint PDF for 2 random variables. So, the statement is: a = 1 - cumsum(P,1)./repmat(sum(P,1),[number_of_hist_bins 1]); number_of_hist_bins is the number of bins of the joint histogram in any given dimension. So, the 1-cumsum(P, 1) is somehow maybe the reliability/survival function. So if P is a joint PDF then summing along the dimensions would give the marginal PDFs and cumulative summing would give the CDF and 1-CDF is the survival function from what I could find on wikipedia. However, I have no idea what the division by repmat(sum(P,1), [number_of_hist_bins 1]) is doing... I have a feeling that this is some sort of marginalisation but I cannot convince myself. sum(P, 1) is the marginal PDF, so there is a normalisation of the CDF with the PDF going on but I cannot fathom to what end... I was wondering if anyone here has seen this sort of thing before and maybe it some standard definition that I might have missed. I would be really grateful if someone can help me figure it out...

I don't have the answer to your question, but I'm curious what sort of block codes you'd like to MAP-decode. It's practical for small Hamming codes. A few years back near-MAP decoding of Hamming constituent codes in a turbo code configuration was popular for awhile, so you could try searching for those implementations.
