Structurally describe the above design in with 2x1 MUX as a component. Describeentity and architecture of 2x1 MUX

To describe the above design using a 2x1 MUX as a component, we need to understand the entity and architecture of a 2x1 MUX.

Entity of 2x1 MUX: The entity of a 2x1 MUX includes two input signals (A and B), one select signal (S), and one output signal (Y). The entity declaration can be written as follows:

entity mux_2x1 is port ( A, B : in std_logic; S : in std_logic; Y : out std_logic ); end entity mux_2x1;

Architecture of 2x1 MUX: The architecture of a 2x1 MUX describes how the inputs are selected and mapped to the output based on the select signal. In this case, we can use a conditional statement (if-else) to implement the functionality of the 2x1 MUX. The architecture can be written as follows:

architecture behavioral of mux_2x1 is begin process (A, B, S) begin if S = '0' then Y <= A; else Y <= B; end if; end process; end architecture behavioral;

In this architecture, if the select signal (S) is '0', the output (Y) will be equal to input A. Otherwise, if the select signal is '1', the output will be equal to input B.

By using this 2x1 MUX component, we can describe the above design by connecting the appropriate inputs and outputs to the inputs and outputs of the 2x1 MUX.
