Seminar on INTEL CORE I7 PROCESSOR : 

Seminar on INTEL CORE I7 PROCESSOR BY K.DHANA SEKHAR

INTRODUCTION: 

They are the best desktop processor family on the planet. You'll multi-task applications faster and unleash incredible digital media creation. It maximize performance to match your workload. The Intel Core i7 Processor is a revolution in multi-core performance. With faster, intelligent micro architecture that applies processing por dynamically when needed most, the new Intel Core i7 processors deliver an incredible breakthrough in PC performance . INTRODUCTION

Definition: 

Intel core i7 is a family of three Intel desktop processor, the first processor released using the Intel Nehalem micro architecture and the successor to the Intel Core 2 family. All three models are quad core processors Definition

HOW IT WORKS: 

The instruction decoder has three decoder units that can decode one simple instruction per cycle per unit . The other decoder unit can decode one instruction every cycle, either simple instruction or complex instruction made up of several micro-ops . Instructions made up of more than four micro-ops are delivered from the MSROM . Up to four micro-ops can be delivered each cycle to the instruction decoder queue (IDQ). The IDQ delivers micro-op stream to the allocation/renaming stage of the pipeline. HOW IT WORKS

EXACT WORKING NATURE OF I7 PROCESSOR: 

It is an higher turbo boosting frequency which increases its voltage and frequency without violating the power. The i7 processor is idle for its power gating, as the power gating aims to cut the leakage current as well, thereby further reducing the power consumption of the idle core. EXACT WORKING NATURE OF I7 PROCESSOR

NATURE: 

The number of active cores, the estimated current consumption, and the estimated power consumption. Normally , the Core i7 processor can operate at frequencies between 1.5 GHz and 3.2 GHz (the maximum non-Turbo Boost frequency or the base frequency) in frequency steps of 133.33 MHz. With Turbo Boost enabled, the processor can increase the frequency of cores two further levels to voltage, and thermal envelope. NATURE

LAUNCH OF I7 PROCESSOR: 

Intel representatives state that Core i7 is meant to help consumers decide which processor to purchase as the ner Nehalem-based products are released in the future. The name continues the use of the Intel Core brand. Core i7, first assembled in Costa Rica , was officially launched on November 17, 2008[11 ] A nd is manufactured in Arizona , New Mexico and Oregon . LAUNCH OF I7 PROCESSOR

FEATURES OF I7 PROCESSOR: 

QUAD-CORE PROCESSING Provides four independent execution cores in one processor package. Four dedicated processing cores help operating systems and applications deliver additional performance End users can experience better multitasking and multithreaded performance across many types of applications and workloads. FEATURES OF I7 PROCESSOR

PowerPoint Presentation: 

INTEL HYPER-THREADING With Intel Hyper-Threading Technology, highly threaded applications can get more work done in parallel, completing tasks sooner. With more threads available to the operating system, multitasking becomes even easier.

PowerPoint Presentation: 

INTEL TURBO BOOST TECHNOLOGY Dynamically increases the processor’s frequency as needed by taking advantage of thermal and por headroom when operating below specified limits . Get more performance automatically, when you need it the most.

PowerPoint Presentation: 

8 MB INTEL SMART CACHE This large last-level cache enables dynamic and efficient allocation of shared cache to all four cores to match the needs of various applications for ultra-efficient data storage and manipulation

PowerPoint Presentation: 

INTEL QUICK PATH INTERCONNECT Intel’s latest system interconnected design increases bandwidth and lords latency, while achieving data transfer speeds as high as 25.6 GB/s.

PowerPoint Presentation: 

ENABLING EXECUTE DISABLE BIT FUNCTIONALITY It requires a PC with a processor with Execute Disable Bit capability and a supporting operating system. Check with your PC manufacturer on whether your system delivers Execute Disable Bit functionality.

PowerPoint Presentation: 

INTEGRATED MEMORY CONTROLLER An integrated memory controller with three channels of DDR3 1066 MHz offers memory performance up to 25.6 GB/s. Combined with the processor’s efficient perfecting algorithms, this memory controller’s lord latency and higer memory bandwidth delivers amazing performance for data-intensive applications.

PowerPoint Presentation: 

DIGITAL THERMAL SENSOR ( DTS) Provides for more efficient  processor and platform thermal control improving system acoustics. The DTS continuously measures the temperature at each processing core . The ability to continuously measure and detect variations in processor temperature enables system fans to spin only as fast as needed to cool the system.

PowerPoint Presentation: 

INTEL WIDE DYNAMIC EXECUTION Improves execution speed and efficiency, delivering more instructions per clock cycle. Each core can complete up to four full instructions simultaneously

PowerPoint Presentation: 

INTEL SMART MEMORY ACCESS Improves system performance by optimizing the use of the available data bandwidth from the memory subsystem and reducing the effective latency of memory accesses

FEW OTHER FEATURES ARE A SMARTER WAY TO WORK AND PLAY SHATTER YOUR LIMITS

DESIGN AND IMPLEMENTATION: 

Nearly all modern CPUs represent numbers in binary form; with each digit being represented by some two-valued physical quantity such as a "high" or "low" voltage related to number representation is the size and precision of numbers that a CPU can represent. DESIGN AND IMPLEMENTATION

DESIGN AND IMPLEMENTATION: 

In the case of a binary CPU, a bit refers to one significant place in the numbers a CPU deals with. The number of bits (or numeral places) a CPU uses to represent numbers is often called "word size", "bit width", "data path width", or "integer precision" when dealing with strictly integer numbers (as opposed to floating point ). This number differs between architectures, and often within different parts of the very same CPU DESIGN AND IMPLEMENTATION

PERFORMANCE OF PROCESSOR: 

The performance or speed of a processor depends on e.g. the clock rate and the Instructions per Clock (IPC), which together are the factors for the Instructions Per Second (IPS) that the CPU can perform. PERFORMANCE OF PROCESSOR

PERFORMANCE: 

Many reported IPS values have represented "peak" execution rates on artificial instruction sequences with few branches, whereas realistic workloads consist of a mix of instructions and applications, some of which take longer to execute than others. PERFORMANCE

TYPES OF PLATFORMS: 

INTEL I3 CORE PROCESSORS Two new Intel Core i3 and three new Core i5 mobile processors also unveiled at the same time . Out of these the new Core i3 processors are clocked beten2.13GHz for Core i3-330M and 2.26GHz for Core i3-350M. Both processor shave Thermal Design Poor rating of 35W. These Core i3 are mostly made for light-light notebooks but won’t offer Intel Turbo Boost Technology to increase the CPU clock speed for higher performance. TYPES OF PLATFORMS

TYPES OF PLATFORM: 

INTEL CORE I7 PROCESSOR Both pairs of low-voltage and ultra-low voltage processors will offer Intel Turbo Boost Technology to increase the performance Four other dual-core Intel Core i7 chips were reintroduced of which two are for low-voltage family (2.0GHz Core i7-620LM and 2.13GHz Core i7-640LM) and other two are for ultra-low voltage family (1.06GHz Core i7-620UM and 1.2GHz Core i7-640UM ) TYPES OF PLATFORM

TYPES OF PLATFORMS: 

Both pairs of low-voltage and ultra-low voltage processors will offer Intel Turbo Boost Technology to increase the performance . The low-voltage Intel Core i7 mobile chips have TDP rating of 25W while the ultra-low Core i7 chip shave TDP rating of 18W. TYPES OF PLATFORMS
