Introduction of processor

• Integrated circuit
• Controls all of the system components
• Execute computer programs
• Processor is also called brain of the computer
• Operation and Instruction in processor

4
Use of heat sink and fan in processor

• Silver metal strips on the side of the processor
• Draw heat away from the processor
• Prevent processor from overheating and melting

5
Registers and its type
Local memory location where data is temporarily
stored. Overall number of registers can vary
depending upon the types of processor. The main
registers- 1) Accumulator register Stores the
result of arithmetic and logical operations 2)
Status register Holds system status
indicator 3) Instruction register Contains the
current instruction being processed
6
4) Ordinal counter Contains the address of the
next instruction to process 5) Buffer
register Temporarily stores data from the memory
7
Functional Units
Processor is made up of group of interrelated
units. Types of units- 1) Control unit Controls
the flow of data. Gets its instruction in the
form of code. Translate the code. 2) Arithmetic
and logical unit Handles all the mathematical
calculations. Performs logical comparisons. Takes
command from control unit. Performs them and
store in the memory.

Cache Memory

• Reduces waiting times for information stored in
  the RAM.
• Have greatly increased cost.
• Temporarily store the primary data to be
  processed.
• Types of Cache memory-
• Level one cache memory
• Level two cache memory
• Level three cache memory

Technology Improvements
1) Parallel Processing Simultaneous use of more
than one processor. Makes program run faster. 2)
Multi Processing Simultaneous use of more than
one processor or computer. Computers are joined
by high speed channel to share the workload. 3)
Hyper Threading Placing of two logic processor
with a physical processor. Multitasking system.
10
Factors affecting the performance of processor

• Clock Speed
• Speed of internal bus, address bus, data bus
• Amount of RAM
• Cache memory
• Multi Processing

11
Conclusion
Thus, it is one of the most important and amazing
parts of the PC, and also the most amazing
devices in the world of technology. All work
that we do on our computer is performed directly
or indirectly by the processor.
