| CPU AND TINGZ | GLHF :) |
| What do the following do in a CPU? | By - Sam - Wright |
| Program Counter | Tells You which instruction you are on in a program, also holds address of next instruction. |
| Accumulator | Used to store data and results of any calculations from the ALU. |
| Arithmetic Logic Unit | Used to process any maths or logic. Loads data from registers. |
| Controll Unit | Gilds the flow of data for the program counter. Also tells the CPU and RAM if its reading or writing data. |
| Memory Data Register | Holds temporary data which is being sent to or from RAM. |
| Data Bus | Sends data to the CPU and from the RAM. |
| Controll Bus | Sends information to the RAM, telling it whether it needs to read or write. |
| Memory Adress Register | Holds the address of where data is being loaded or stored. Also holds the address to be sent to the RAM. |
| Current Instruction Register | Holds the current instruction that has been used by RAM. |
| Harvard Architecture | Allows two different memory locations, one for data and another for instructions. This allows both data and instructions to be received at the sane time. |
| Von Neumann Architecture | Only has RAM which holds both data and instructions. Can only send one at a time. |
| Clock Speed | Tells you how many tasks a CPU can execute per second. |
| Core | Receives instructions and performs tasks. More cores allows for more tasks to be executed. E.g two cores means twice as fast. |
| Adress Bus | Sends information about where data needs to go. It gives the address to the memory location. |
