Harris and David Money Harris, Digital Design and Computer Architecture: ARM Edition 2015 by Elsevier Inc. Exercise SolutionsCHAPTER 1Exercise (a) Biologists study cells at many levels. The cells are built from organellessuch as the mitochondria, ribosomes, and chloroplasts. Organelles are built ofmacromolecules such as proteins, lipids, nucleic acids, and biochemical macromolecules are built simpler molecules such as carbonchains and amino acids. When studying at one of these levels of abstraction, bi-ologists are usually interested in the levels above and below: what the structuresat that level are used to build, and how the structures themselves are built.

It can receive inputs from LVCMOS and LVTTL gates be-cause their output logic levels are compa tible with this gate’s input levels. How-ever, it cannot drive LVCMOS or LVTTL gates because the 1.2 VOL exceeds the VIL of LVCMOS and LVTTL. Exercise 1.83 (a) XOR gate; (b) VIL = 1.25; VIH = 2; VOL = 0; VOH = 3 Exercise 1.85 BC Y 00 01 10 11 A 0 0 ...
