====== Foundational Concepts ======

This lecture covers //three// major topics: The Big Picture (how this course fits in CSE), the Software-Hardware Interface (the Source-to-Execution Journey), and Performance (barriers and innovations).



===== Outline =====

  * The view from 40,00 feet
  * A journey through abstractions

  * The software part and the O/S
  * The hardware part and the architecture

  * Performance terms
  * Performance drivers



===== Big Ideas =====

  * Building Blocks
  * The ISA

  * The role of system software (compiler and O/S)
  * The von Neumann Architecture
  * The Fetch-Execute Cycle

  * Latency versus Throughput and Speedup
  * Size, Heat, and Speed
  * Buffering, Caching, and Pipelining
  * Moore's Law
