Taking image as input

--- Quote Start ---

Try with a .mif file related to a lpm_rom megafunction.

In this file you should include the image contents, organized, i.e, by rows.

This matlab function takes a matlab vector var and creates a .mif file of depth cells and width bits each one.

function miffile(filename,var,width,depth)

fh=fopen(strcat(filename,'.mif'),'w+');

fprintf(fh,'WIDTH=%d;\r\n',width);

fprintf(fh,'DEPTH=%d;\r\n',depth);

fprintf(fh,'ADDRESS_RADIX=DEC;\r\n');

fprintf(fh,'DATA_RADIX=DEC;\r\n');

fprintf(fh,'CONTENT BEGIN\r\n');

for k=1:length(var)

fprintf(fh,strcat(num2str(k-1),':',num2str(var(k)),';\n'));

end

fprintf(fh,'END;\r\n');

fclose(fh);

Matlab stores the image as a matrix, you should resize it as a vector.

in order to read the ROM include two counters, index_column and index_row.

index_rom=index_row*(columns_per_row) + index_column

In the above matlab code what do you mean by filename in the arguments.....should i need to give image name...if so i gave the filename as avergra2.bmp (function miffile(avergra2,var,width,depth))

can you also explain what is the purpose of index_rom (the last command)
