This function selects from input streams based on tags.
In this primitive, each tag decides the source of the output. It is assumed that input element has a corresponding channel-selection tag. The output data in data_ostrms only contains the input data .
Parameters:
| _TIn | the type of input data |
| _WTagStrm | the width of tag, pow(2, _WTagStrm) is the number of input streams. |
| data_istrms | the input streams |
| e_data_istrms | the end flag of input streams |
| tag_istrm | the tag stream, streams and data_istrm and tag_istrm are synchronous. |
| e_tag_istrm | the end signal stream, true if data_istrms and tag_istrm are ended. |
| data_ostrm | the output stream. |
| e_data_ostrm | the end signals of data_ostrm. |
| alg | algorithm selector |
