2. 22 3. Introduction of a processor Before discussing about i3 processor, let a smallintroduction of processor. A processor is the logic circuitry that responds to andprocesses the basic instructions that drive a computer. The term processor has generally replaced the termcentral processing unit (CPU). The processor in a personalcomputer or embedded in small devices is often called amicroprocessor. 3 4. Brief introduction about i3 processor The only question I have is if theres any advantage tousing a Core i3 over a Core2Duo. The Core i3 is a 3.2 GHz dual core chip, and its quite a bigimprovement over the Core2Duo. Its a good 700 MHzfaster, much faster bus with significantly faster RAM. The first Core i3 processors were launched on January 7,2010.4 5. the single core5 6. Multi-core CPU chipThe cores fit on a single processor socket .Also called CMP(Chip Multi-ProcessorTask level and Tread level parallelism.6 7. 7 8.

Smart Cache is a level 2 or level 3 cache method for multipleexecution cores invented by Intel.It shares the cache among coresIt decrease the cache miss rate.It provide peak transfer rate of 96GB/sec .15 16. 16 17. Improve the performance.It aim to locate data as close as possible to reduce memorylatency time.It also include Memory disambiguation.17 18. 18 19. Malicious buffer overflow attacks pose a significant securitythreat to businesses.These attacks cost businesses precious productivity time, whichcan equal significant financial loss.It allows the processor to classify where application code can executand where it cannot in the memory.When a malicious worm attempts to insert code in the buffer,the processor disables code execution.19 20.
