FPGA笔记-读取.dat文件

读取.dat图像文件

.dat文件是matlab生成的图像文件

	initial begin
		// Initialize Inputs
		CLK = 0;
		RST = 1;
		IMAGE_DATA = 0;
		BUFFER_WEN = 0;
		// Wait 100 ns for global reset to finish
		#10000;
                RST = 0;
		#100;
		RST = 1;
		// Add stimulus here
		$display("read image data from exp.dat file TO memery begin");
		$readmemh ("C:/Users/Administrator/Desktop/Noise_Reduce/ReadData/exp.dat",RData);
//		$readmemh ("C:/Users/Administrator/Desktop/Noise_Reduce/Noise/data.dat",RData); //读取.dat 内的16进制数据函数，.dat文件只能有空格和回车
		$display("send every pixel to TOP level HDL when every CLK negedge ");
		# 10;
//		@(negedge CLK);
//		@(negedge CLK);
			for(i=0;i<65536;i=i+1)
			begin
				 BUFFER_WEN = #1 1;
				 $display("send pixel RData[%d] to IMAGE_DATA is :  %d",i,RData[i]);
				 @(negedge CLK);
				 IMAGE_DATA = #1 RData[i];
			end
		 BUFFER_WEN = #1 0;	
	end
