Computer Architecture ● “Architecture” ● The art and science of designing and constructing buildings ● A style and method of design and construction ● Design, the way components fit together ● Computer Architecture ● The overall design or structure of a computer system, including the hardware and the software required to run it, especially the internal structure of the microprocessor

CS305 Prerequisite ● Logic Design (CS210) ● Switching theory ● Number systems, computer arithmetic ● Logic circuits, combinatorial logic, K-maps ● Finite state machines in hardware ● Arithmetic unit, control unit design ● CAD, FPGA ● VHDL

CS305 Course Contents ● Computer organization, von Neumann arch. ● Instruction set design ● Measuring performance, Amdahl's law, CPI ● Datapath and control path ● Pipelining, hazards

CS305 Course Contents (continued) ● Memory hierarchy, cache design, cache performance ● Disk storage ● RAID ● Error correction codes, Hamming codes ● I/O Buses

Why Important? Q: Why do you think Computer Architecture is important (or unimportant)? Identify Computer Architecture around you

Scenario-1: Watch TV || Record

Scenario-2: SMS Gone, AC On

Scenario-4: Rural Computing

Scenario-5: Horn-Ok-Please

Why Important? Q: Why do you think Computer Architecture is important (or unimportant)? ● Computing central to information age ● Computer systems range from very small to very large, low-end to super-computers ● New computing devices, end-user devices ● How are they designed? What affects their performance?

Course Evaluation ● Homework assignment(s): 15% ● Quizzes: 15% ● Mid-sem: 25% ● End-sem: 45% ● Companion course: CS341: Computer Architecture Lab ● Assembly language programming, learning concepts through simulator (SPIM) based implementation

Students vs. Exam-Takers ● Student: – Attend all classes, arriving on/before time – Exceptions require (1) written explanation (2) prior permission – Attention in classes – Integrity in work: exams, homeworks, labs, etc. ● Exam-takers – Attendance optional ● Declare yourself as student or exam-taker ● Student --> exam-taker transision is easy and automatic ● Exam-taker --> student transition is hard

Student-Teacher Relationship ● Being a student is a pre-requisite for teacher-student relationship ● (Only) By being a student, you can: ● Ask questions in class ● Request deadline extensions ● Negotiate on exam re-evaluations ● I will do my best to hold my end of the bargain

How You Learn is Important ● Aspects of “how you learn” ● Commitment and hard-work ● Time-management ● Group learning ● Integrity: most important – Strict policy on dishonesty – Cheating OR helping cheat ==> FR grade
