Computer architecture: The Fetch-Execute cycle

This cycle is called

• Execution Cycle

• The Fetch-Execute cycle

• Fetch Cycle

The first stage in The Fetch-Execute cycle is Fetch Instructions

• True

• False

The Fetch-Execute cycle mean how the instructions are executed and process data

• True

• False

The ALU performs arithmetic and logical operations on all required data. It carries out instructions and also performs the operations on various registers. If it is necessary to get more data for a specific instruction, then they are transferred from the main memory to the registers.

• Executing of instructions

• Decoding of instructions

• Storing of results

• Fetching of instructions

The results of executing instructions are placed in the main memory.

• Executing of instructions

• Decoding of instructions

• Storing of results

• Fetching of instructions

The instructions are transferred from the main memory and stored temporarily in small memories within the CPU called registers.

• Executing of instructions

• Decoding of instructions

• Storing of results

• Fetching of instructions

The control unit interprets the instruction stored in the instruction register, turning it into a signal that can be understood by the ALU.

• Executing of instructions

• Decoding of instructions

• Storing of results

• Fetching of instructions

The Second stage in The Fetch-Execute cycle is --------------

• Fetch Instructions

• Restore results

• Execution Cycle

• Decode Instructions

The Third stage in The Fetch-Execute cycle is --------------

• Fetch Instructions

• Restore results

• Execution Cycle

• Decode Instructions

The Last stage in The Fetch-Execute cycle is Restore results

• True

• False
