how to convert mfile to vhdl code with out similink model

is mcode block useful to convert of mfile, is the mcode block support the wavread command

Answer 1

HDL Coder has supported HDL code generation from MATLAB code since R2012a. However, it does not and will never support the wavread function. The reading of any external file needs to be done by your testbench code. Supporting a complex command like wavread implies a filesystem on external storage, and high-level synthesis to perform external file IO in hardware.

HDL Coder has many image processing demos where the testbench reads an image and passes it into the hardware design. Audio processing is very simpler with this technique. I suggest you study the demos to understand this approach.

thank you very much sir for your immediate response.. my problem in hdl code generation is that while we are running Recursive Least Square (RLS) demo noise cancellation. we could not able to generate HDL (Tools->HDL Coder-> Generate HDL). We are getting errors summary --> ERROS FROM HDLSHARED:HDLSHARED:SIMULINKFRONTEND:REPORT ISSUES:FRONTENDERROS and 1.rls1/RLS FILTER/Frame-Based RLS Filter/Update/Stabilize /in Matrices are not supported in this release. 2.rls1/RLS FILTER/Frame-Based RLS Filter/Update/Stabilize /sum2 3.rls1/RLS FILTER/Frame-Based RLS Filter/Update/Stabilize /conj1 ... We couldn`t able to figure out the problem. Kindly please suggest us to rectify our errors. Thank you in advance.

The relevant part of the error message is:

rls1/RLS FILTER/Frame-Based RLS Filter/Update/Stabilize /in:
Matrices are not supported in this release.

The named signal is a matrix; it has some dimensions MxN. HDL Coder does not support matrices in general, although that is being improved. You will need to convert the data type to either N Mx1, or M 1xN, vectors.

i have matlab 2013a. To learn HDL coder, i tried same example given here i.e 'mlhdlc_sfir.m'. but i am getting error in conversion of floating point to fixed point. can you please help me with, the where problem may be. i am getting error while build like Error in Float2FixedConverter>buildDesign at 1699

Error in Float2FixedManager>buildFloatingPointCode at 102 is there installation problem or what..?

I wonder if you need a C compiler installed in 13a to build mex files. can you try "mex -setup"? Thanks.
