Can anyone gimme an idea of implementing sum of squares of arithmetic on FPGA.. a verilog or VHDL codin wud be really useful

with regards,
 

Here is a Verilog module that continuously counts, squares the count value, and accumulates the squares.

Code: 
module top (clk, sum);
  input             clk;
  reg        [15:0] count = 0;
  output reg [31:0] sum = 0;

  always @ (posedge clk) begin
    count <= count + 1;
    sum <= sum + count * count;
  end
endmodule

  end
endmodule

i agree with this code.. but how is it advantageous over the mathematical formula for the sum of squares,

n*(n+1)*(2n+1)/6;

is it becoz it requires more multiplication and a division every time???

and moreover, when wll ur module end?

The original question was very simple, so I gave a minimal example. He didn't say what values he wanted to square, so I used a counter. He didn't say when it should stop, so it doesn't stop.

I'm guessing he is starting to learn Verilog, and needed a simple "hello world" example to build upon.
