Weekly Schedule

First Half

Week	Topics	Reading
Week 1 1/30	Friday Introduction Syllabus Digital circuits Mini-Lab: just to get the idea!	Skip Chapter 1.
Week 2 2/6	Monday Boolean Algebra Truth tables Venn diagrams examples of schematics from Nasa logic gates and gate (7408) or gate (7432) not gate (7404) Wednesday Boolean functions canonical forms: the minterm canonical form Friday Exercises on the duality of Boolean Logic Translating Schematics into a boolean function. Verifying truth tables in Python Mystery Circuit: Lab #1 Homework #1	Start your reading with Chapter 2 on Boolean Algebra. Binary numbers Boolean algebra and Logic Gates Basic theorems Truth tables Boolean functions Canonical forms George Boole
Week 3 2/13	Monday Maxterm Canonical Form Nand/Nor circuits Wednesday Rules of simplification and lazy evaluation by compilers... Karnaugh Maps The Decoder Exercises on Karnaugh maps, nands, and majority voters Don't Care conditions in Karnaugh Maps Friday Lab #2 Homework #2 and Solutions	Reading Karnaugh Maps Decoders
Week 4 2/20	Monday (Image from Eniac image Clemson U.) Comments on transistors and gates Equivalent of a Decoder in Java or Python? Karnaugh maps for 3, 4, and 5 variables. Don't care conditions with Karnaugh maps Wednesday Exercises Decoders with an enable input. (moving toward microprocessor architecture) Friday Decoders and Multiplexers in Computers IBM PC Schematics (circa 1984): spot the decoders! RAM Lab #3 Homework #3
Week 5 2/27	Monday Something to study for a while... Answer of the day: It's a sequential circuit: it behaves differently depending on initial conditions! It's a machine with 2 states: it has a state diagram! We cannot use a truth table to represent its behavior It has memory: it can store a bit Why does it work? Because the two gates that form this circuit can be eith blocking or passing, and when they are passing, the state, whichever it is, is stable. End of the lecture was with timing diagrams, and showing that Q and Q' can be in either one of the possible cases: 01 or 10, and we show that on the timing diagram. Wednesday Friday

PSpice 9

• Pspice 9, Student version. An nice alternative to drawing schematics by hand.
• This is a Windows version. (I have tried to make it work under wine/Mac OS X but haven't been able to make it load the libraries correctly)
• Make sure you select the schematics option when installing the software.
• Select Tools/Schematics when starting the editor
• The schematics editor is located in C:\Program Files\OrCAD_Demo\PSpice\PDesign.exe upon installation.

Motorola 68HC11 Documentation

• Good source of info on the 6811.
• 6811 FAQs.
• The official Motorola | 68HC11A8 Data Sheet. Fairly cryptic...
• A Motorola 6811 Manual. It is a nicely written refresher on many concepts of assembly language applied to the 6811.
  • Check Section 3.2 on addressing modes (inherent, direct, extended, indexed, relative).
  • Get a refresher for the different instruction types (arithmetic, shifts, control, etc) in Section 3.4.
  • The condition code register is covered in Section 3.5.
• M68HC11 Technical Reference, Motorola
  • Section 6.5 shows the instructions in logical groups.
• M68HC11 Pocket Reference.
  • Very useful, on Page 15, a list of all the opcodes supported by the 6811, in numerical (hex) order.
• 68HC11A8 Technical Reference: a hardware and engineering description. of the 6811, its ports, and how it operates.
  • See Section 10 for a cycle-by-cycle description of the execution of each instruction.
  • See Appendix A, Figure A-14 for the timing diagram of a typical (multiplexed expansion) memory access.
