Witryna3 lut 2015 · I also did some conversions between the incompatible types in VHDL. The third file I created is a test bench that I simulated to check the implementation. So, the 1-digit BCD adder is: library ieee; use ieee.std_logic_1164.all; use ieee.numeric_std.all; entity bcd_adder is port( a,b : in unsigned(3 downto 0); -- input numbers. Witryna26 sty 2012 · Shift functions (logical, arithmetic): These are generic functions that allow you to shift or rotate a vector in many ways. The functions are: sll (shift left logical), srl (shift right logical). A logical shift inserts zeros. Arithmetric shifts (sra/sla) insert the left most or right most bit, but work in the same way as logical shift.
