CS250 Midterm Review Guide

Topics

• Binary Arithmatic
• ASCII, you don't have to memorize the table
• Memory and Bandwidth, not in much detail this time
• How circuits work (so if you had an example, you could figure out what it does!)
• Power (Units: watts, amps, volts, ohms) P = IV (power = current times voltage), V = IR (voltage = current times resistance)
• Parts of a Computer, don't have to memorize socket numbers.
• Gates and Logic
• Clocks and Memory, in principle
• Assembly Programming:
• Registers, know the x86 registers
• Common instructions like mov, push, pop, add, sub, call, jmp (and conditional variants), cmp, ret, mul, div
• Function calling conventions, know how these work and the first couple registers for x86-64 on Linux and where the return value ends up
• Stack frames (%rbp vs. %rsp)
• Triggering Interrupts
• Arrays and data items, like lab 4
• Not integrating C and assembly
• printf, will be used for "what does this print?" questions
• Not malloc
