**What This Document Is**
These are lecture notes from Computer Systems Architecture I (CSE 560M) at Washington University in St. Louis, specifically covering Lecture 05. The material delves into the complexities of pipelined processors, building upon foundational concepts to explore how program structure impacts performance. It’s a core component of understanding how computer hardware executes instructions efficiently. The notes also introduce the critical topic of exception handling within a pipelined architecture.
**Why This Document Matters**
This resource is invaluable for students enrolled in advanced computer architecture courses. It’s best utilized *during* and *immediately after* the corresponding lecture to reinforce understanding and fill in any gaps in note-taking. It’s also a strong foundation for tackling homework assignments and preparing for exams related to pipelining and fault tolerance. Anyone seeking a deeper understanding of how processors manage interruptions and maintain data integrity will find this material beneficial.
**Common Limitations or Challenges**
These notes are a record of a specific lecture and are designed to *supplement*, not replace, textbook readings or independent study. They do not offer a complete, self-contained introduction to computer systems architecture. The notes assume a pre-existing understanding of basic computer organization and assembly language concepts. Furthermore, while the notes outline key challenges, they do not provide detailed, step-by-step solutions to resolving them.
**What This Document Provides**
* A refresher on the core principles of pipelining and its performance benefits.
* An overview of the challenges introduced by exceptions (interrupts, faults) in a pipelined environment.
* Discussion of the considerations for handling exceptions precisely to maintain system stability.
* Exploration of how different functional units within a processor (integer, floating-point) impact pipeline efficiency.
* Identification of potential hazards (structural, RAW, WAW) that can arise in a pipelined architecture.
* An introduction to the complexities of handling multicycle operations within a pipeline.
