    Reverting from a std_logic_vector(0 to n) to std_logic_vector(n downto 0)

    Hello everybody:wink:, i want to ask if anybody knows how to invert the bits order from a std_logic -vector from a 0 to n to -> n downto 0 For example i am having the signal s : std_logic_vector(0 to 3) := "1010" and i want it to be 0101 3 downto 0? Is there some kind of function?? Thanks for...

    Floating point in VHDL and FPGA

    Hello everybody, Does anyone know how to implement signed floating point operations like addition or multiplication in vhdl that would be synthesizable for FPGAs? And if there aren't any libraries available any hints how to represent in vhdl(for FPGA) this floating numbers? Code samples would...
