Physical View of MPU & MCU:

Historical Background

Fairchild

  • –   Fairchild Semiconductors founded in 1957, invented the first IC in 1959.
  • –   In 1968, Robert Noyce, Gordan Moore, Andrew Grove resigned from Fairchild Semiconductors.
  • –   Found their own company Intel (Integrated Electronics).
  • –   Intel grows from 3 man start-up in 1968 to industrial giant by 1981.
  • –   It had 82,500 employees (2010) and $53.34 Billion revenue(2012).

Timeline:

  • –   1947-Invention Of Transistor
  • –   1959-Invention Of Integrated Circuit
  • –   1965-Birth Of Moore’s Law
  • –   1971-Development of First Microprocessor-4004
  • –   1971-Development of First Microcontroller-TMS1000
  • –   2011 May 2, , Intel announced its first 22 nm microprocessor, codenamed Ivy Bridge, using a technology called 3-D Tri-Gate

 

Gorden Moore’s Law

”The number of transistors on integrated circuits will double approximately every 24 months.”

 moores law

 So what changes do they do actually?

Bring in Advanced Micro-architecture technology which puts in more and more no. of transistors on a unit sized chip

 

Key Features Of MPU & MCU:

  • Smaller Size
  • Lower Cost
  • Higher Reliability
  • Lower Power Consumption-CMOS
  • Higher Versatility
  • More Powerful

 

Bridge between College and Real Life Scenario-Work Of Intel Engineer

What do these Engineers do?[1]

–   Process Engineers-develop the most efficient methods for semiconductor manufacturing using state-of-the-art equipment and materials

–   Yield Engineers– work closely with process engineers to improve product yield and to troubleshoot process flow from root causes to equipment tuning

–   Equipment Engineers–  own and lead the stability, improvement, maintenance and performance functions of extremely advanced tools

–   Design Automation and Computer Aided Design (CAD) Engineers– design, develop, maintain, and provide user support of CAD tools, assist with schematic entry and analysis in the integrated circuit design process, and create and implement computer-controlled automatic test systems. In all of these tasks, their core objectives are simple—to improve quality and reduce costs

–   Hardware and Software
Product Development- ensuring the testability and manufacturability of integrated circuits, optimizing component production, and evaluating, developing and debugging complex test methods. Working with our process technology development and product teams, these individuals help deliver the best process and design effective reliability models based on ROI, process limitations, Q&R requirements and product usage models

–   Component Design and Validation–  responsible for chip layout, circuit design, circuit checking, device evaluation, and validation. Starting with product requirements and logic diagrams, they plan design projects and help address the unique needs of our customers

–   Research and Development– Explore how customers interact with technology, what they love about it, and how to make off-the-wall ideas usable reality. Whether you’re applying new materials, emerging technologies or customer insights, your innovations will be what transforms the computing capabilities of tomorrow.

–   Threads-4 Threads 2/4Threads-8
–   Hyperthreading-Yes–   Hyperthreading-Yes/NoHyperthreading-Yes
–   Turbo Boost-No–   Turbo Boost-Yes/YesTurbo Boost-Yes
–   32 nm technology–   32/45 nm technology32-45 nm technology

 

 

Meaning Of Pratik has 64-Bit Laptop???

  • –   It means the Microprocessor has 64 data bus lines.
  • –   So if you have 32 bit Microprocessor, then it means that there are 32 data lines .

Meaning of 256 MB Memory

–   256 =2^8

–   So there are in total 8 address lines

 

Leading Companies In MPU:

 intel

INTEL

 

 

  • –   Integrated Electronics founded in 1968
  • –   Paul Otellini –CEO
  • –   Headquarter-Santa Clara ,California
  • –   Intel has also begun research in electrical transmission and generation
  • –   It has 23,000 employers
  • –    Intel has recently introduced a 3-D transistor that improves performance and energy efficiency.
  • –   Intel has begun mass producing this 3-D transistor, named the Tri-Gate transistor, with their 22 nm process, which is currently used in their 3rd generation core processors initially released on April 29, 2012
