How to use matlab to generate sine wave coe file
Editor to share with you how to use matlab to generate sine wave coe files, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!
Use matlab to generate sine wave coe file
When we use ROM in xilinx ISE, we often use .coe file, and coe file is the initialization file of xilinx ROM.
Examples of Coe files:
MEMORY_INITIALIZATION_RADIX=10; stands for base 10, 2 for base 2, 8 for base 8, and 16 for base 16.
MEMORY_INITIALIZATION_VECTOR=
2500
2663

Sin0=sin (2*pi*f*t) * 3.25-3.25
Fid = fopen ('E:\ ise_project\ audio\ coe\ sim_rom0.coe','w');% file storage path
Fprintf (fid,'MEMORY_INITIALIZATION_RADIX=%d;\ nJournal width)
Fprintf (fid,'MEMORY_INITIALIZATION_VECTOR=\ n')
For (k=1:N-1)
Fprintf (fid,'%d,\ nPhonology sin0 (k))
End
Fprintf (fid,'%d;\ nseparate Chinese 0 (N));% each data is separated by a comma or space or newline character, and the last data is followed by a semicolon
Plot (trecoery sin0 and Zhonghua')
Results:
Use da output oscilloscope to display the results on FPGA:
