After clicking henerate HDL code to run, the operation page is directly stuck and no operation can be carried out. MATLAB can only be forcibly closed. And no Verilog was produced。

If I close MATLAB directly, the following error report will appear. But if I wait for it to run, MATLAB will jam.

So when I changed the output to multiple parallel structures, and I continued to run henerate HDL code, the program, just like it did before, just stuck. Continue to close MATLAB, at this time a new error.

error:Compilation errors when generating code for: Matrix/jvzhen\Selector1 Error during MATLAB code compilation: Error Path: B:\matlab\src\cgir_hdl\emlinterface\EMLInterfaceForHDL.cpp:407 Error Location: (@Row: --> 5 @Column: --> 14) Compilation aborted by user. Internal Error: This error occurred inside a MathWorks function.

Can you share your model or reach out to tech support for further guidance on the topic?

In general this model seems to be using large matrices at the IO. You have two options.

Manual frame to sample conversion; reduce the IO usage by passing samples into the dut; use additional valid, ready signals to control the IO frames.

sry,sir.Maybe I didn't give you enough information。

This is the part of the m file I ran, and then I used the Simulink model to produce the matrix.I chose this picture.

The problem is that the program runs for a long time, around 10 hours, and 3.2genereteRTL is still reporting an error and running out of memory

clear;clc;
u = 1;
v = 2;
w = 3;
kernel = 9; 
layer = 2;
img_path = '../picture/sssna.jpeg';    
[img, m, n, lambd] = system2(img_path);    
save lambd lambd

system1

function [U, V, W, X] = system1(U,V,W,n)
for i = 1:50
    U = mod(15*U, 251);
    V = mod(14*V, 241);
    W = mod(11*W, 239);
end
for i = 1:n
    U = mod(15*U, 251);
    V = mod(14*V, 241);
    W = mod(11*W, 239);
    X(i) = mod(U+V+W, 256);
end
end

system2(img_path)

 function [img,m,n,lambd] = system2(img_path)
I = imread(img_path); 
img = I(:, :, 1); 
[m, n] = size(img); 
m = fi(m,0,32,0);
n = fi(n,0,32,0);
encrypts = hash(img, 'sha1'); 
for i = 1:20
    lambd(i) = hex2dec(encrypts(2*i-1:2*i));
end
lambd = fi(lambd,0,32,0);  
end

Arash, Would you be able to share a sample model? Thanks.

wang, I hope you got MathWorks tech support on your thread; my initial comment still applies. You can browse examples like >> mlhdlc_demo_setup('heq') to see how to convert your code to streaming fashion.
