Introduction
Modern processors are complex devices that can have bugs. Furthermore, instead of executing x86 instructions directly, modern x86 processors contain internal code that implements support for the x86 instruction set. The internal code is called microcode. Microcode can be updated to fix or mitigate CPU bugs.
