This week in CS107e

Week 1
Lecture Mon 3/30	Welcome and intro to RISC-V ( slides, code ) After a quick recap of course logistics, we dive right in to RISC-V and the Mango Pi MQ-Pro SBC we will be using this quarter. 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 ) RISC-V ISA and assembly language. Arithmetic and logical operations, load and store instructions. Control flow using branch/jump. 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 Enjoy Danny Cohen's article Holy Wars and a Plea for Peace on the history of little-endian vs. big-endian.
