Briefly define the following terms : i. Micro-operation ii. Micro-instruction iii. Micro-program iv. Micro-code v. Control memory

i. Micro-operation:

• Definition: A set of actions that the processor needs to perform to complete the main phases of the instruction cycle (fetch, decode, and execute).
• Example: Fetching data, decoding instructions, executing operations.

ii. Micro-instruction:

• Definition: Individual control words within a micro-routine, containing control signals for managing the sequence of information.
• Example: Specific commands that tell the processor how to perform a particular task within an instruction.

iii. Micro-program:

• Definition: Micro-code specific to a processor implementation, often created through micro-programming.
• Example: Low-level instructions tailored for a particular processor architecture.

iv. Micro-code:

• Definition: Hardware-level instructions and data structures that help implement higher-level machine code instructions. It separates machine instructions from the underlying electronics.
• Example: Binary-coded instructions that guide the processor in executing machine code.

v. Control memory:

• Definition: A type of Random Access Memory (RAM) with addressable storage registers used for temporary storage of data.
• Example: Storing control signals and instructions that guide the CPU’s operation.
