Characteristics of Processors  Funtions  Is the central processing unit, performing all the processing, calculation and control systems.  The basic components of the CPU  Control unit (CU: control unit) Control operation of the system according to the translated program available  Arithmetic & Logic Unit (ALU: Arimethic Logic Unit) Perform arithmetic and logic  Set of registers (Registers) Used to store information temporarily for CPU activity. Include the address register, data registers, instruction register and the flags register.

Operatings  For the CPU, so the information processing in the CPU is completely automated by the program is available in memory.  CPU execution through three steps:  F (Fetch).  D (Decode).  E (Execute). Time CPU execute

 Done, then proceed with the next CPU reads the next command.  Here are the steps that the CPU must be done sequentially. Operatings

The specifications of CPU  Cache  FSB – Front Side Bus  DIP, PGA, LGA  Hyperthreading  Multicore  Throttling  Microcode  Overclocking  Speed  System Bus

 Cache  Cache is a very fast chip memory that is used to hold data and instructions that are most likely to be requested next by the CPU  L1 cache: the cache located on the CPU (L1 data cache, L1 instructions cache)  L2 cache: located on the motherboard.  L3 cache: new cache, only in the modern generation CPU The specifications of CPU

 FSB – Front Side Bus  Front Side Bus (FSB) is the bus that carries data between the CPU and the Northbrigde. The specifications of CPU

 DIP, PGA, LGA The specifications of CPU

The specifications of CPU

 Hyperthreading  This term refers to Intel’s Hyper-Threading Technology (HTT).  The operating system can schedule two processes at the same time, as in the case of symmetric multiprocessing (SMP), where two or more processors use the same system resources. The specifications of CPU

 Multicore  A processor that exhibits a multicore architecture has two completely separate processors in the same package.  Throttling  is the process of controlling how much CPU time is spent on an application.

 Microcode  is the set of instructions set that make up the various microprograms that the processor executes while carrying out its various duties.  Overclocking  Overclocking your CPU offers increased performance.  The speed  The speed of the processor is generally described in clock frequency (MHz or GHz).  System Bus (32- and 64-Bit)  The set of data lines between the CPU and the primary memory of the system can be 32 or 64 bits wide.
