The correct answer is A) A layer of low-level instructions, stored in special memory within the CPU, that translates complex machine instructions into a sequence of simpler hardware-level operations
A
Correct Answer
A layer of low-level instructions, stored in special memory within the CPU, that translates complex machine instructions into a sequence of simpler hardware-level operations
Explanation
Microcode acts as an interpreter layer between the ISA-visible instructions and the underlying hardware control signals, allowing complex instructions to be implemented as sequences of simpler micro-operations, and enabling some bug fixes via microcode updates.
