WebCS107 Guide to x86-64. Guide to x86-64. A CS107 joint staff effort (Erik, Julie, Nate) x86-64 (also known as just x64 and/or AMD64) is the 64-bit version of the x86/IA32 instruction set. Below is our overview of its features that are relevant to CS107. There is more extensive coverage on these topics in Chapter 3 of the B&O textbook. The importance of CMP applies mostly in conditional code execution (Jump - See : assembly_conditions).
