unsigned_divider.vhd

$component unsigned_divider is generic ( dividend_width : positive; divisor_width : positive ); port ( clk : in std_ulogic; --# {{}} input_ready : out std_ulogic; input_valid : in std_ulogic; dividend : in u_unsigned; divisor : in u_unsigned; --# {{}} result_ready : in std_ulogic; result_valid : out std_ulogic; quotient : out u_unsigned; remainder : out u_unsigned ); end component;$

Calculates

dividend / divisor = quotient + remainder / divisor

This is a bit serial divider. Algorithm is the same as long division from elementary school, but with number base two. Latency scales linearly with dividend_width.
