1.1.1 Structure and Function of the Processor Flashcards
What is the definition for Opcode (Operation Code) ?
Opcode is an instruction for the CPU to process and run.
What is the definition for Operand?
Data for the CPU to run an instruction for the CPU to process
What is the definition for address bus,and which direction does it go?
Transmits the address of data to be loaded from the CPU to memory.
Address Bus goes in 1 direction only: CPU to Memory
What is the definition for data bus and which direction does it go?
The data bus transmits data between different components.
Data Bus goes in both directions
What is the definition of control bus,and which direction does it go?
Transmits command , timing and status information between components.
Control bus goes in both directions.
What is the definition for an Input Device?
Any hardware giving information to the computer.
What is the definition for an Output device?
Any hardware giving information to the user.
What is the definition for the Control Unit?
Decodes instructions.Sends control signals to co-ordinate the movement of data through the processor.
What is the definition for Cache Memory?
Memory in the CPU used to store frequently stored instructions.
What is the preocess for Multiprocessing?
Each core can complete a different task at the same time.
several problems can be completed currently.
Most programs can therefore run faster.
What is Harvard Architecture?
Data and Instructions are stored and fetched separately.
Harvard Architecture can process instructions and data at the same time.
