TDATA Structure - 7.2 English

The input DATA and output DATA channels share a common tdata structure format, though can have different bit widths. All parallel data paths ( Parallel Data Channel Filters ) and parallel data samples ( Super Sample Rate Filters ) are contained in the tdata bus, with each path being sign extended to an 8-bit boundary. The extra bits on the input tdata are not used by the core.

This Figure shows the tdata structure for a case with 2 parallel paths (data streams). In this case, bit growth is experienced between input and output—a path width of 11 bits on the input grows to 13 bits on the output.
