  1. There are a fixed number of registers in the CPU
    • Registers hold data
    • Data move from Memory to Registers
    • Results move from Registers back to Memory
  2. There is an 1-cache in the CPU that holds recently fetched instructions.
    • If you execute a loop that fits in the cache, the CPU goes to memory for those instructions only once, then executes them out of its cache.
