### Course Description
This is a second computer organization course and focuses on computer hardware
design. In this course you will design and implement a pipelined, superscalar
processor for a simple RISC ISA using Verilog. You will learn the range of
architectural techniques used in modern CPU design including superscalar design,
out-of-order execution, and cache hierarchies.
### Frequently Asked Questions
* What happened to CIS 371 and CIS 501?
CIS 471/571 was called CIS 371/501 in previous semesters. It has been renumbered
to fit the standard university numbering scheme for cross-listed undergrad/grad
courses. There is no substantive change to the content from previous years.
* What's the difference between CIS 471 and CIS 571?
There is **no** difference in the course content (assignments, exams, etc.)
between CIS 471 and 571. If you are a graduate student, you'll need to take CIS
571.
* Do all group partners need to be in the **same** course number?
No, one member can be in CIS 471 while the other is in CIS 571.
### Prerequisites
CIS 240 and knowledge of at least one software programming language. We do not
assume you have any prior experience with Verilog.
### Course Materials
The main textbook is *Computer Organization and Design: The Hardware/Software
Interface* by Patterson and Hennessy. The 4th and 5th Editions are both
fine. The 4th Edition is available [for free on-line through the Penn
Library](http://hdl.library.upenn.edu/1017.12/876659).
*Introduction to Logic Synthesis using Verilog HDL* by Reese and Thornton is
also a nice introduction to hardware design and Verilog. It is also available
[as a free PDF via the Penn
Library](http://www.morganclaypool.com/doi/abs/10.2200/S00060ED1V01Y200610DCS006).
I like [*Digital Design: A Systems
Approach*](https://www.cambridge.org/us/academic/subjects/engineering/circuits-and-systems/digital-design-systems-approach?format=HB&isbn=9780521199506)
by Dally and Harting. I'm not aware of a free version, and it's not a required
text, but I do think it gives a nice explanation of many of the topics we'll
cover in class.
