Interleave items from multiple streams based on a provided pattern (given as a vector).
Parameters
- IO Type
- Supported types are: complex, float, int, short, and byte
- Pattern
- Vector that represents the interleaving pattern.
- For example, the pattern
[ 0, 0, 1, 2 ]means to pass one item of data from port 0 twice, then from port 1 once, then from port 2 once, then repeat. - The number of inputs is set by max(pattern,0) + 1.
- Note, all inputs must be connected even if all are not used in the pattern. For example, the pattern
[0, 0, 1, 2, 4]would create 5 inputs. The fourth input (pattern val 3) is unused but the flowgraph will not run.
- Vector Length
- The vector length for the input stream(s).
Example Flowgraph
Example 1
An example flowgraph using the default pattern with vector length 1 streams:
An example of the settings field:
An example of the beginning of the output sequence:
The output pattern begins with: 0, 1, 10, 20, 2, 3, 11, 21, 4, 0, 12, 22, ....
Example 2
This example shows a vector length 2 example:
An example of the beginning of the output sequence:
The output pattern for the first stream begins with: 0, 1, 10, 20, 2, 3, 11, 21, 4, 0, 12, 22, ....
The output pattern for the second stream begins with: 1, 2, 11, 21, 3, 4, 12, 22, 5, 0, 13, 23, ....
