Write VHDL code for a RAM that has 16 locations each 32 bits wide. There will be a chipselect (CS) input that activates the chip. Another input to the circuit is an R/W which determines if the operation is a read or a write to the chip. The address input to the chip is a vector. The input and output would also be a vector(s) that should send and receive the data, depending on the address input to the chip.

Hello your question lacks some parts attached is the complete question and the solution is written in the explanation

Explanation:

VHDL CODE::::::

VHDL Code for RAM Design:

library IEEE;

use IEEE.STD_LOGIC_1164.ALL;

use IEEE.STD_LOGIC_ARITH.ALL;

use IEEE.STD_LOGIC_UNSIGNED.ALL;

entity RAM_32Bits is

port (

Clk: in std_logic;

CS: in std_logic;

RW: in std_logic;

Address: in std_logic_vector(3 downto 0);

Data_In: in std_logic_vector(31downto 0);

Data_Out: out std_logic_vector(31downto 0);

)

end entity RAM_32Bits;

architecture RAM_32 of RAM_32Bits is

// Declare Memory Array

type RAM is array (3 downto 0) of std_logic_vector(31 downto 0);

signal mem_array: ram;

// Signal Declaration

signal read_addr: std_logic_vector (3 downto 0);

begin

process (Clk)

begin

if (Clk’event and Clk=’1’) then

if (CS=’1’ and RW=’1’) then

ram(conv_integer(Address)) <= Data_In;

endif;

if (CS=’1’ and RW=’0’) then

read_addr <= Address;

endif;

else

read_addr <= read_addr;

endif;

endprocess

Data_Out <= ram[conv_integer(read_addr)];

end architecture RAM_32;
