You can use the & operator to concatenate std_logic and std_logic_vector. For example, the following assignment makes a 7- bit result, where the top two bits are '1', the bottom bit is 0, and the remaining 4 are from the vector value. y <= "11" & value (3 downto 0) & '0'; Complete the architecture below to divide the 8-bit unsigned input by 2, truncating (ignoring) any fraction. The output should also be 8 bits. Do not use the VHDL division or shift operators instead, think about what happens when you divide a binary number by 2, and figure out how do that by manipulating bits. If it helps, think about what happens when you divide a decimal number by 10. 1 library IEEE; 2 use IEEE.std_logic_1164.all; 3 entity div2 is port( 4 5 6 7 8 9 10 11 architecture synth of div2 is 12 begin 13 result <= x"00"; at least this works for 0 and 1….. 14 end; 15 16 operand in std_logic_vector (7 downto 0); result out std_logic_vector(7 downto 0) ); end div2; Rollback to previous You can use the & operator to concatenate std_logic and std_logic_vector.
