CS107e Spring 2026

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.

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.
