frequency of the sine wave is 1 khz .
Max Amplitude of the sine wave is 4.97 V in IEEE 754 floating point format
Similarly other values values of the wave which is converted in to 16 bit binary .
Want some ideas to create an alogarithm at first to use this values to find phase difference of the sine wave .
The LUT created till know to read the values :
Memory Created :
module ram_memory_2(clk,add,data);
input [5:0]add;
input clk;
output reg [15:0]data;
always @ (*)

case(add)

You can search this table to find positions and subtraction of two addresses give you phase difference. Next time you can use some linear approximation for more precise results.
