Microcode
Microcode is a low-level set of instructions embedded in a computer's central processing unit (CPU) that translates higher-level machine code into specific hardware operations. It acts as an invisible intermediary, enabling efficient execution, bug fixes, and performance tweaks without redesigning the chip itself. In today's tech landscape, microcode is crucial for maintaining compatibility and security in processors amid rapid software evolution.
Did you know?
Microcode updates played a pivotal role in patching the Meltdown and Spectre vulnerabilities discovered in 2018, which exploited speculative execution in CPUs and threatened data security on over 90% of the world's devices, prompting rapid industry-wide responses from chip manufacturers like Intel and AMD.
