Computer Systems

Used to identify a memory location to be read from or written to.

Part of the processor where calculations and decisions are made.

Transfers in both directions.

Includes timing/control logic and an instruction decoder. It sends signals to other parts of the computer to direct the fetch and execution of machine instructions.

Separate functions include initiating a read or a write to/from memory

Used to transfer data to and from the CPU.

The memory address of the next instruction is placed on the address bus, read line is activated on the control bus, the instruction is transferred to the processor on the data bus, and instruction is decoded and executed.

A function of the control bus which transfers data from the main memory to the processor

Temporary storage areas within the processor

Transfers data in one direction only.

A function of the control bus which transfers data from the process or to main memory

A function of the control bus which provides the internal timer to synchronize events between system components.

Frequency at which a CPU executes instructions, measured in GHz.

More than one processors on the same chip, which gives them the capability of executing separate instructions at the same time

More bits can be transferred in one clock cycle

A small amount of SRAM that sits between the processor and RAM in order to speed up data transfer by requiring less fetch-executes
