Notes/Equations
- This model is used to implement transport block concatenation and code block segmentation.
- Each firing, one transport format indicator token is consumed at TFIin. This value is used to select the transport block size and transport block set size from the transport format set, as specified by DynTFSet. CRC bits are attached to each transport block.
- Each firing, the number of tokens consumed at DataIn must be equal to the CRC encoded transport block set size.
- The segmented block number and block size is the output at BlkNum and BlkSize. The data stream is output at DataOut.
