Update 19 June 2022: exercises PDF based on 2022 notes posted.
Update 17 June 2022: Numerous updates.
Update 14 August 2020: Table 3.3 corrected.
Update 31 October 2019: Figure 4.6 corrected; the instruction should be addi with
-42 not subi with 42. Why? It is
unnecessary to have both instructions since the value is encoded in an immediate instruction so it can easily be
negated. It is a waste of instruction coding to have both a subtract and add immediate
