Now you might wonder if these kinds of bugs can be fixed after the fact. Well, sometimes they can, sometimes they can't. CPUs are not purely hard-coded beasts, they rely on microcode for part of their operation. Traditionally microcode is a set of internal instructions that the CPU ran to execute external instructions. That's mostly not the case anymore, and modern microcode ships not only with implementations of complex instructions but also a significant amount of configuration. 16/31
