Microcode - Wikipedia
WEBIn processor design, microcode serves as an intermediary layer situated between the central processing unit (CPU) hardware and the programmer-visible instruction set architecture of a computer, also known as its machine code.
What exactly is microcode and how does it differ from firmware?
WEBJan 8, 2018 · Processor microcode is akin to processor firmware. The kernel is able to update the processor's firmware without the need to update it via a BIOS update. A microcode update is kept in volatile memory, thus the BIOS/UEFI or kernel updates the microcode during every boot.

Demystifying Microcode Updates for Intel and AMD Processors
WEBNov 11, 2019 · When processors are manufactured, they have a baseline microcode baked into their ROM. This microcode is immutable and cannot be changed after the processor is built. Modern processors do have the ability at initialization to apply volatile updates to move the processor to a newer microcode level.
Intel microcode - Wikipedia
WEBIntel microcode is microcode that runs inside x86 processors made by Intel. Since the P6 microarchitecture introduced in the mid-1990s, the microcode programs can be patched by the operating system or BIOS firmware to work around bugs found in the CPU after release.
