- architecture rtl of comb_mltplr is
- begin -- rtl
- -- purpose: Multiply the multiplicand with the multiplicator.
- -- type : combinational
- -- inputs : dvdnd_i, dvsor_i
- -- outputs: product_o
- p_mltply: process (mltplctr_i, mltplcnd_i)
- variable v_product : unsigned(DWIDTH*2-1 downto 0);
- begin -- process p_divide
- v_product := conv_unsigned(unsigned(mltplctr_i)
- * unsigned(mltplcnd_i),DWIDTH*2);
- product_o <= std_logic_vector(v_product);
- end process p_mltply;
- end rtl;
