CS161 Goal Introduction to Computer Architecture Familiarity with processor components (pipeline, caches, registers, etc. ) Provide foundation for further comp arch courses CS162 – Computer Architecture CS203 – Advanced Computer Architecture 4

Topics Covered Prerequisite: CS/EE 120A Background Quantifying Performance, Technology Trends, … Instruction Set Architecture CPU Design Single cycle, Multi cycle Processor Pipelining 5-stage pipeline Memory hierarchy Memory, Cache, Virtual Memory Reliability RAID 5

Why learn Comp Arch? Computer Architecture is the glue that binds software and hardware Inter-disciplinary in nature Devices, Circuits, OS, Runtime, PL, Compilers Advancement of computer architecture is vital to all other areas of computing IoT, Embedded Mobile Data centers, HPC 6

What is Computer Architecture? Hardware organization of computers how to build computers Layered view of computer systems Role of the computer architect: To make design trade-offs across the hw/sw interface to meet functional, performance and cost requirements 7
