MATLAB 产生任意波形数据存储到FPGA的ROM

参考代码如下：

close all;

% % 正弦波=============================================================
amp = 100e3; %幅值
depth = 400e3; %深度（采样点个数）
x = 0:1:depth; % 1个周期，400e3个点
y = amp*sin(2*pi*x/400e3) + amp; 
y = int32(y);
plot(x,y,'-o');
fid = fopen('sin.coe','w');
fprintf(fid,'memory_initialization_radix=10;\n');
fprintf(fid,'memory_initialization_vector =\n');
fprintf(fid, '%d,\n', y);
fclose(fid);

% 锯齿波=============================================================
amp = 100e3; %幅值
depth = 400e3; %深度（采样点个数）
x = 0:1:depth; % 1个周期，400e3个点
y = x/2; 
y = int32(y);
plot(x,y,'-o');
fid = fopen('sawtooth.coe','w');
fprintf(fid,'memory_initialization_radix=10;\n');
fprintf(fid,'memory_initialization_vector =\n');
fprintf(fid, '%d,\n', y);
fclose(fid);

% 三角波=============================================================
amp = 100e3; %幅值
depth = 400e3; %深度（采样点个数）
x = 0:1:depth; 
y=depth/4*sawtooth(2*pi*x/depth,0.5) + amp;  % 0.5 是最大值的位置
y = uint32(y);
% y = round(y * (2 ^ (width - 1) - 1) + 2 ^ (width - 1) - 1);%量化
plot(x,y);
fid = fopen('triangular.coe','w');
fprintf(fid,'memory_initialization_radix=10;\n');
fprintf(fid,'memory_initialization_vector =\n');
fprintf(fid, '%d,\n', y);
fclose(fid);

% 方波=============================================================
amp = 100e3;    %幅值
depth = 400e3;  %深度（采样点个数）
x = 0:1:depth; 
y=2*amp*square(2*pi*x/depth,50); %50 为占空比
y = uint32(y);
plot(x,y,'-o');
figure;
fid = fopen('square.coe','w');
fprintf(fid,'memory_initialization_radix=10;\n');
fprintf(fid,'memory_initialization_vector =\n');
fprintf(fid, '%d,\n', y);
fclose(fid);

FPGA中添加ROM


设置好数据深度和宽度，然后选择导入的数据
