Operator SplitParallel

Operator Library: Base

The operator splits the input link of parallelism degree N into N output links of parallelism degree 1. The amount of output links N has to be specified on operator instantiation. The number of links has to be equal to the number of parallel pixels of the input link and cannot be changed after operator instantiation. If the input parallelism changes, a new instantiation of the operator is required. The opposite of this operator is 'MergeParallel'.

The following figure illustrates an example for input parallelism four.

1

The range of the input bit width is [1, 64]. For signed inputs, the range is [2, 64]. For unsigned color inputs, the range is [3, 63] and for signed color, the range is [6, 63].

Parameters

None

Examples of Use

The use of operator SplitParallel is shown in the following examples:

  • 'Hardware Test'

    An example for hardware self test of DMA, RAM, GPIOs, Trigger and LEDs.

  • 'Downsampling 3x3'

    Examples - Downsampling by factor 3x3 without the use of operator SampleDn.

  • 'Line Mirror'

    Examples - Shows how to vertically mirror an image. Note the mirroring of the parallel words and the pixel.

  • 'Tap Geometry Sorting'

    Examples - Scaling A Line Scan Image
