| The CPU | The ALU is a digital circuit used to peform arithmetic and logic operations. The Cache is used to store frequently used data, shorten data access times and improve application performance. The control unit controls and monitors the hardware attached to the system and does commands. |
| The VN Architecture Buses | |
| Fetch - Decode - Execute Cycle | The first step the CPU carries out is to fetch some data and intrustions from the main memory. The CPU uses the address bus. The next step is for the CPU to decode the instructions it has just fetched. Then, the instruction is carried out and executed. |
| Worked Example of Fetch Decode Execute | |
| Registers | In a computer, a register is one of a small set of data holding places that are part of a computer processor . A register may hold instructions , a storage address, or any kind of data (such as a bit sequence or individual characters). Some instructions specify registers as part of the instruction. |
| Registers 2 | A register must be large enough to hold an instruction - for example, in a 32-bit instruction computer, a register must be 32 bits in length. Depending on the processor design and language rules, registers may be numbered or have arbitrary names. |
| Overclocking Cores | Overclocking your cores is a good way to unleash your CPU's full optential. However, you must make sure your computer is able to deal with this. |
| Embedded Computers | An embedded computer is a single chip that contains all of the elements that are essential for any computer i.e. RAM, ROM, CPU, Input,Output, Clock. Telephones, televisions, camera, washing machines, microwave cookers, dishwashers and cars all have embedded computers. |
