used to determine the type of instruction and what hardware to use to execute it.

the address of where the operation is performed.

a programming language where mnemonics are used to represent instructions

the address of where the operation is performed.

used to determine the type of instruction and what hardware to use to execute it.

a programming language where mnemonics are used to represent instructions

What occurs during the fetch phase?

The address from the PC is copied to the MAR,

Instruction held at that address is copied to the MDR by the data bus, simultaneously the contents of the PC is increased by 1,

The value of the MDR is copied to the CIR

The contents of the CIR is split into operand and opcode.

The opcode is executed on the data.

What occurs during the decode phase?

The contents of the CIR is split into operand and opcode.

The address from the PC is copied to the MAR,

Instruction held at that address is copied to the MDR by the data bus, simultaneously the contents of the PC is increased by 1,

The value of the MDR is copied to the CIR

The opcode is executed on the data.

What occurs during the execute phase?

The opcode is executed on the data.

The address from the PC is copied to the MAR,

Instruction held at that address is copied to the MDR by the data bus, simultaneously the contents of the PC is increased by 1,

The value of the MDR is copied to the CIR

The contents of the CIR is split into operand and opcode.

What is the clock speed?

The number of clock cycles completed per second.

the CPU’s onboard memory which can be accessed a lot faster than main memory

The process of completing the fetch, decode and execute of three separate files simultaneously

It is used to synchronise instructions.

What is cache memory?

the CPU’s onboard memory which can be accessed a lot faster than main memory

The number of clock cycles completed per second.
