Hello! I have to design a RPN calculator that can perform +, -, AND, OR and brackets using VHDL. I used Dijkstra's Shunting Yard Algorithm to transform the introduced expression into a postfix expression (this works fine). However, the calculation part isn't working. I saved the postfixed...
Thank you for your answers! I tried to code the RPN calculator that you suggested in your first reply. This is what I got so far:
library ieee;
use ieee.std_logic_1164.all;
use ieee.std_logic_unsigned.all;
entity calculator2 is
port(x: in std_logic_vector(4 downto 0);
operation: in...
Thank you for your answer! I tried to write the code for the calculator using the stacks that you suggested. This is how I codified the operations: A+B: 00000, A-B: 00001, A AND B: 00010, A OR B: 00011, (: 00100, ): 00101, =: 11111 and this is what I have written so far:
library IEEE;

Hello, I have to project a specialized calculator on a Basys3 board using VHDL. The calculator should be able to group numbers using brackets, perform additions and substractions, AND and OR operations. For example, an expression could be: 4 + 5 AND 6 +(7 OR 1) - (4 AND 10)
The input numbers...
