An alternative to this description is a process that contains a FOR LOOP with the XOR operation. - the second has a more behavioural view, it count the numbers of ones. Both result in the same logic (witjh my synthesis tool) Regards, Egbert Molenkamp ENTITY parity1 IS GENERIC (nbits: positive:= 3); PORT (d: IN bit_vector(nbits-1 DOWNTO 0); odd: OUT bit; even: OUT bit); END parity1; ARCHITECTURE xor_chain OF parity1 IS SIGNAL chain: bit_vector (nbits DOWNTO 0); BEGIN chain(nbits).
