Schedule

Below is a preview of our week-by-week plan for the entire quarter. There may be slight adjustments and rearrangements as we go. The schedule for the final project is set and will not change.

In the readings below, K&R refers to Kernighan and Ritchie's classic text The C Programming Language (accessible via Stanford's subscription to Safari Books Online). Nick Parlante's EssentialC is another great C reference. Please do the recommended readings before lecture for best effect!

Week 1
Lecture Mon 3/30	Welcome and intro to RISC-V ( slides, code ) After a quick recap of course logistics, we dive right into the RISC-V ISA and the Mango Pi MQ-Pro SBC we'll be using this quarter. Introduce instructions for arithmetic and logical operations. Readings: For background, review our guides on electricity, binary/hexadecimal numbers, and the unix command line. Bookmark this collection of unix video tutorials that were prepared for CS107 students. These videos cover basic concepts, common utilities, development tools, and productivity features. An interactive tour of Mango Pi board The Ripes RISC-V simulator demoed in lecture. Our one-page guide to RISC-V. A "for fun" diversion: Steven Wolfram's blog post Untangling the Tale of Ada Lovelace traces the work of Charles Babbage and Lady Ada Lovelace to develop the concept of a general-purpose computer.
Lab/assign	Lab 0: Orientation ( writeup ) Please do the Lab 0 prelab preparation before coming to lab.	Assignment 0: Git oriented ( writeup )
Lecture Fri 4/3	RISC-V assembly and machine code ( slides, code ) More RISC-V assembly: control flow using branch/jump, load and store instructions, instruction encoding and decoding. Tools to build and execute an assembly program. GPIO peripheral control via memory-mapped I/O. Readings: Here is a link to the Ripes simulator demoed in lecture. If you have a printout of the one-page guide to RISC-V, bring it along! From D1-H User Manual: Ch9.7 GPIO Course guides on Meet your GPIO pins and Programming your GPIO pins Enjoy Danny Cohen's article Holy Wars and a Plea for Peace on the history of little-endian vs. big-endian.
Week 2
Lecture Mon 4/6	From Assembly to C ( slides, code ) Moving up from assembly to C. Implementation of C expressions and control structures. Readings: Brush up on C basics (syntax, data types, operators, control structures) via your favorite C reference; sections 1-2 of Nick Parlante's EssentialC; or chapters 1, 2, and 3 of K&R. Skip content on I/O and standard libraries (we are bare metal!) Read Dennis Ritchie's account of the history of C Try out the Compiler Explorer demoed in lecture Read our guides on make and gcc
Lab/assign	Lab 1: Getting to know your Mango Pi ( writeup ) Please do the Lab 1 prelab preparation before coming to lab.	Assignment 1: Larson Scanner ( writeup )
Lecture Fri 4/10	C Pointers and Arrays ( ) Memory, addresses, and pointers. Address arithmetic, layout of arrays and structures. Typecast and `volatile`. Readings: Review EssentialC chapters 3 and 6 (postpone heap and memory management for later) or K&R 5.1-5.4. C `volatile` can be subtle and tricky. See GeeksForGeeks advice on correct use and John Regehr's blog on what NOT to do with volatile
