Hi.
I am doing a project - Calculator using FPGA board.. however, i am facing problems writing the Verilog code for addition of numbers.. the input is in ascii code, which i need to convert into binary first, then carry out the addition, and finally reconvert it back to the ascii code.. so if someone knows how to write this code or has even some little idea about how to go through with this, please help me out..Link Copied

First I would suggest you create look up table that converts ascii to binary and back again. The addition of binary numbers will be straight forward.

Actually, I'm a novice at Verilog, so i don't really know about look up tables.. i tried googling too, but i didn't get anything worthwhile.. could you help me out with that too please??
Thanks :)- Mark as New

I'm more of a VHDL guy but it would be something like this.
always @(posedge clk) begin case (ascii_value) h'30: binary_value = h'0; h'31: binary_value = h'1; ... ... ... endcase end- Mark as New

By nature, all digital logic quantities are binary. Decimals can be e.g. presented as binary coded decimal (BCD) numbers or 1 out of 10 decoded signal. You should specify the function of intended logic more exactly.
