Rotate 1D Array (G Dataflow)
Rotates the elements of an array a specified number of places and direction.
array
n
The number of places and the direction to rotate array.
If n is positive, the indices of elements move right, and if n is negative, the indices of elements move left. For example, if n is 1, all elements in array move right one index place, so the first element becomes the second element and the last element becomes the first. If n is -1, all elements move left one index place, so the second element becomes the first element and the first element becomes the last. The node coerces n to a 32-bit integer if you wire another representation to it.
rotated array
For example, if n is 1, the input array[0] becomes rotated array[1], input array[1] becomes rotated array[2], and so on, and input array[m-1] becomes rotated array[0], where m is the number of elements in the array. If n is -2, input array[0] becomes rotated array[m-2], input array[1] becomes rotated array[m-1], and so on, and input array[m-1] becomes rotated array[m-3], where m is the number of elements in the array.
Data Type Changes on FPGA
When you add this node to a document targeted to an FPGA, this output has a default data type that uses fewer hardware resources at compile time.
Where This Node Can Run:
Desktop OS: Windows
FPGA: All devices (only within an optimized FPGA VI)
Web Server: Supported in VIs that run in a web application
