Introduction of a processor

 Before discussing about i3 processor, let a small
  introduction of processor.

 A processor is the logic circuitry that responds to and
  processes the basic instructions that drive a computer.

 The term processor has generally replaced the term
  central processing unit (CPU). The processor in a personal
  computer or embedded in small devices is often called a
  microprocessor.



                                                               3
Brief introduction about i3 processor

 The only question I have is if there's any advantage to
  using a Core i3 over a Core2Duo.

 The Core i3 is a 3.2 GHz dual core chip, and it's quite a big
  improvement over the Core2Duo. It's a good 700 MHz
  faster, much faster bus with significantly faster RAM.

 The first Core i3 processors were launched on January 7,
  2010.




                                                                  4
the single core




        5
Multi-core CPU chip




The cores fit on a single processor socket .Also called CMP
(Chip Multi-Processor


Task level and Tread level parallelism.
                                                              6

Its also provide help to run 32bit O.S. on 64 bit
                                                    13

Smart Cache is a level 2 or level 3 cache method for multiple
execution cores invented by Intel.

It shares the cache among cores


It decrease the cache miss rate.


It provide peak transfer rate of 96GB/sec .



                                                                15
16
Improve the performance.

It aim to locate data as close as possible to reduce memory
latency time.

It also include Memory disambiguation.




                                                              17
18
Malicious buffer overflow attacks pose a significant security
threat to businesses.

These attacks cost businesses precious productivity time, which
can equal significant financial loss.

It allows the processor to classify where application code can execut
and where it cannot in the memory.

When a malicious worm attempts to insert code in the buffer,
the processor disables code execution.
                                                                  19

  • 3. Introduction of a processor  Before discussing about i3 processor, let a small introduction of processor.  A processor is the logic circuitry that responds to and processes the basic instructions that drive a computer.  The term processor has generally replaced the term central processing unit (CPU). The processor in a personal computer or embedded in small devices is often called a microprocessor. 3
  • 4. Brief introduction about i3 processor  The only question I have is if there's any advantage to using a Core i3 over a Core2Duo.  The Core i3 is a 3.2 GHz dual core chip, and it's quite a big improvement over the Core2Duo. It's a good 700 MHz faster, much faster bus with significantly faster RAM.  The first Core i3 processors were launched on January 7, 2010. 4

  • 19. Malicious buffer overflow attacks pose a significant security threat to businesses. These attacks cost businesses precious productivity time, which can equal significant financial loss. It allows the processor to classify where application code can execut and where it cannot in the memory. When a malicious worm attempts to insert code in the buffer, the processor disables code execution. 19
