-- This file contains the definition of KCPSM3 as one complete module with sections -- created using generate loops. This 'flat' approach has been adopted to decrease -- the time taken to load the module into simulators and the synthesis process. -- -- The module defines the implementation of the logic using Xilinx primitives. -- These ensure predictable synthesis results and maximise the density of the implementation. -- The Unisim Library is used to define Xilinx primitives. It is also used during -- simulation. The source can be viewed at %XILINX %\vhdl\src\unisims\unisim_VCOMP.vhd -- ----------------------------------------------------------------------------------- - -- -- Library declarations -- -- Standard IEEE libraries -- library IEEE; use IEEE.STD_LOGIC_1164.ALL; use IEEE.STD_LOGIC_ARITH.ALL; use IEEE.STD_LOGIC_UNSIGNED.ALL; library unisim; use unisim.vcomponents.all; -- ----------------------------------------------------------------------------------- - -- -- Main Entity for KCPSM3 -- entity kcpsm3 is Port ( address : out std_logic_vector(9 downto 0); instruction : in std_logic_vector(17 downto 0); port_id : out std_logic_vector(7 downto 0); write_strobe : out std_logic; out_port : out std_logic_vector(7 downto 0);
