Digital Reversed Order (G Dataflow)

    Last Modified: January 9, 2017

    Modifies the input array according to the digital-reversed order of the index.


    input array

    The real input array this node modifies. The length of input array must be an integer power of radix.

    This input accepts the following data types:
    • 1D array of double-precision, floating-point numbers
    • 1D array of complex double-precision, floating-point numbers
    • 1D array of 32-bit signed integers


    Base of the exponent. radix must be greater than or equal to 2.

    Default: 2


    error in

    Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

    Default: No error


    reversed array

    The input array with modified elements.


    reversed indices

    Corresponding index of the input array for each element in the output array.


    error out

    Error information. The node produces this output according to standard error behavior.

    Algorithm for Calculating reversed array

    When the index of a sequence has the radix-base digits (, this node modifies the sequence X into the digital-reversed sequence Y according to the following equation:

    Y ( a 0 a 1 a n ) = X ( a n a n 1 a 0 )

    For examples of radix-base digits, 2-base is binary and 16-base is hexadecimal.

    The following illustration shows the 2-base reversed order (bit-reversed order) of 8 elements.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported
