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 EE147 – GPU Programming CS/EE 217 – GPU Architecture

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

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

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
