MT DePermute (G Dataflow)

Last Modified: January 9, 2017

Rearranges or depermutes the permuted data.


data in

The input data to depermute so that the generated data is the same as the MT Permute.


permutation array

An array with elements that define the location of the output data samples of the MT Permute. You can use this array to track the locations of elements in the original data input to MT Permute.


error in

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

Default: no error



A Boolean that determines how this node handles buffered data.

TRUE Clears the buffered data, checks the input parameters on a first call, and reflects any change in the input parameter values during subsequent iterations.
FALSE Adds the buffered data to the beginning of data from next iteration, in continuous operations.

Default: TRUE


data out

The depermuted data returned by this node.


error out

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

Theoretical Example of the Depermutation Operation

The following is a theoretical example of the depermutation operation.

If the data in array is 9,21,13,7,17, and the permutation array is 3,2,4,0,1, the data out array would be 7,13,17,9,2, as illustrated in the following figure.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported
