Unused ports grayed out.
The indexing x(n-1), ..., x(n-7) refers to the case of parallel loading and should be
ignored here. This indexing is retained in this figure for consistency with other
figures in this chapter.
To increase the DSP block performance, include the pipeline and output registers.
