"Multi-Way/Multi-Bit Demultiplexor An m-way n-bit demultiplexor (figure 1.11)
channels a single n-bit input into one of m possible n-bit outputs. The selection is
specified by a set of k control bits, where k ¼ log2 m.
The specific computer platform that we will build requires two variations of this
chip: A 4-way 1-bit demultiplexor and an 8-way 1-bit multiplexor, as follows."
"and an 8-way 1-bit multiplexor" should be demultiplexor.
