This function send element from one stream to multiple streams based on tags.

In this primitive, the tag is the index of ouput streams. The input data in data_istrms is distributed to the data_ostrm whose index is tag. Each tag is the index of output streams, and data_istrm and tag_istrm are synchronous.

Parameters:

_TIn the type of input & output data.
_WTagStrm the width of tag, pow(2, _WTagStrm) is the number of ouput streams.
data_istrm the input stream.
e_data_istrm the end signal of input stream.
tag_istrm the tag stream.
e_tag_istrm the end signal of tag stream.
data_ostrms the output stream.
e_data_ostrms the end signals of data_ostrms.
alg algorithm selector.
