ALU design & test

[Kooscii]

result : out STD_LOGIC_VECTOR (31 downto 0);
eq : out STD_LOGIC;
lt : out STD_LOGIC;
op1 : in STD_LOGIC_VECTOR (31 downto 0);
op2 : in STD_LOGIC_VECTOR (31 downto 0);
funct : in STD_LOGIC_VECTOR (2 downto 0));

• Asynchronous
• eq is HIGH when op1 == op2, otherwise LOW.
• lt is HIGH when op1 < op2, otherwise LOW.
• funct:
  • 0: do result = op1 + op2
  • 1: do result = op1 - op2
  • 2: do result = op1 & op2
  • 3: do result = op1 | op2
  • 4: do result = !(op1 | op2)
  • 5: do result = op1 << op2
  • 6: do result = op1 >> op2

Progress

• [x] Functional simulation passed.
• [x] Timing simulation passed.
