8-to-1 Multiplexer

The entity mux8_1 has a data input (i_d) of type std_logic_vector(7 downto 0) representing 8 channels, a selector (i_sel) of type std_logic_vector(2 downto 0) and one output (o_q) of type std_logic.

When i_sel is "000", the output is i_d(0). For "001" it is i_d(1), etc. up to "111" for i_d(7). For any other value, the output is '0'.
