用matlab产生mif文件和hex文件

用matlab产生mif文件和hex文件

(Altera的EDA软件，如maxplus，quartus等用到的初始化rom，ram等的文件格式)
使用方法：
example:
      a=uint8(rand(16,16)*256);
      miffile('randnum.mif',a,8,256);
hex文件生成见11楼

程序：
function miffile(filename,var,width,depth)
%    function miffile(filename,var,width,depth)
%    It creates a 'mif' file called filename,which be written with var.
%    The 'mif' file is a kind of file formats which is uesed in Altera's
%    EDA tool,like maxplus II ,quartus II,to initialize the memory
%    models,just like cam,rom,ram.
%    Using this function,you can easily produce the 'mif' file written
%    with all kinds of your data.
%    If the size of 'var' is shorter than 'depth',0 will be written for the
%    lefts.If the size of 'var' is greater than 'depth',than only 'depth' former
%    data of 'var' will be written;
%    the radix of address and data is hex
%    filename --the name of the file to be created,eg,"a.mif",string;
%    var ----the data to be writed to the file, can be 3D or less ,int or other fittable;
%    width --the word size of the data,width>=1,int;
%    depth --the number of the data to be writed,int;
%
%    because matlab read the matrix is colum first,if you want to write
%    the 'var' data in row first mode, just set var to var';
%
%    example:
%       a=uint8(rand(16,16)*256);
%       miffile('randnum.mif',a,8,256);
