Debian Security Advisory intel-microcode


Debian Security Advisory intel-microcode, updates CPU microcode for some types of Intel CPUs.

Microcode is a computer hardware technique that interposes a layer of organisation between the CPU hardware and the programmer-visible instruction set architecture of the computer.

As such, the microcode is a layer of hardware-level instructions that implement higher-level machine code instructions or internal state machine sequencing in many digital processing elements.
