I'm not very good with VHDL so i was hoping someone could help me design
a controller for a pico processor.
I have the empty architecture code as:
entity pico_cntrl is
Port ( clk : in std_logic; rst : in std_logic; go : in std_logic;
ir : in std_logic_vector(3 downto 0);
ld_in : out std_logic; ld_out : out std_logic;
sel : out std_logic; ld_ir : out std_logic;
ld_a : out std_logic; ld_b : out std_logic;
ld_ccr : out std_logic; ld_tmp : out std_logic);
architecture Behavioral of pico_cntrl is
The instruction set I am trying to impliment are ADD, SUB, AND, OR,
CMPL, IN A, OUT A, MOV, STOP. Thanks very much!
