The Line Buffer takes two lines of data (top line and bottom line) and serializes this into a single stream. The following diagram shows this data path:
The sequencing is such that LBUF0 is being written while LBUF1 is being read. When LBUF0 has been completely written, it will try to write to LBUF1 next. If on the output side LBUF1 has not been completely read, then the data path will stall waiting for the output to finish reading LBUF1 and switch to reading LBUF0 (and visa versa)
