The document discusses the fetch-execute cycle of a CPU. It explains that the CPU has four main parts that affect performance: clock speed, cache size, number of cores, and amount of RAM. It notes that the unit of measurement for clock speed is Hertz and that a CPU running at 1 gigahertz can process 1 billion instructions per second. Finally, it outlines the objectives of understanding the fetch-execute cycle, bit patterns used for instructions, and how to write own CPU instructions.
