Hello!
1.sorry for my poor english
2.i have the following diagram to implement in verilog: http://elf.cs.pub.ro/ac/wiki/_media/teme/tema2/tema_2_top_module_instance.png I want to make an synchronous sequential circuit that processes grayscale images. a)make a blur filter b)make 90 degree rotation c)horizontal flip I have searched and found algorithm that i will use. I do not know how to access image module from process module?
My code look like this: module process( input clk, input [1:0] op, input [7:0] in_pix, output [5:0] in_row, in_col, output [5:0] out_row, out_col, output out_we, output [7:0] out_pix, output done );
always @(posedge clk) begin if(op==0)begin //here i will implement blur algorithm end else if(op==1)begin //here i will implement fliping algorithm end else begin //here i will implement rotation algorithm //I do not know how to access elements of image module!?? //I want to extract elements from the matrix so i can rotate the matrix and //create new rotated matrix?? end end endmodule
module image( input clk, input[5:0] row, input[5:0] col, input we, input[7:0] in, output[7:0] out );
reg[7:0] data[63:0][63:0]; assign out = data[row][col]; always @(posedge clk) begin if(we) data[row][col]
