ECE2030 Syllabus • Grading policy

– 3 Homework assignment: 5% each– 1 Programming assignment: 10%– 3 in-class exams: 15% each – 1 final exam: 30%– [100,90]=A; (90,80]=B; (80,70]=C,(70,55]=D,

(55,0]=F– Will scale…

• All homework: turn-in in the first 5 minutes “in class” of the due day

• All exams: closed books, closed notes, no calculator

• Honor code • Use T-Square (http://tsquare.gatech.edu)

for your homework and exam grades

Objective: Digital Design Principle• Number systems• Boolean algebra• Switch and CMOS design • Combinational logic

– Logic gates– Building blocks: de/mux, de/encoder, shifters,

adder/subtractor, multiplier– Logic minimization– Mixed logic

• Sequential logic– Latches, Flip-flops– Counters– State machines: Mealy/Moore machines

55

Objective: Digital Design Principle

• Memory and Programmable Devices– Register, RAM, ROM, PLA, PAL

• Architectural concept– Instruction set architecture (ISA)– Stored-Program Computer and Sequential

Control (von Neumann architecture)– Datapath– Branches

• Processor and Software Convention– MIPS ISA– Procedural calls: Stack
