"THE NUMBER OF TRANSISTORS INCORPORATED IN A CHIP WILL APPROXIMATELY DOUBLE EVERY 24 MONTHS." —GORDON MOORE

PROCESSING EFFICIENCY – THE DRIVE FOR EFFICIENT COMPUTING

Delivered Performance = Frequency * Instructions Per Cycle

(IPC)Goal is higher performance

and lower power

efficiency: the ratio of the output of a machine, engine, device etc., to the energy supplied to it..

Higher IPC usuallyresults in wider data pathsand/or more Performance

Leakage current and the ability to move charge through the channel have an impact on power

WHAT IS 22 NM TECHNOLOGY…..?

INTEL ANNOUNCED THIS TECHNOLOGY IN MAY 2011.

COMMONLY REFERRED AS TRI-GATE.

WORLD’S FIRST 3D TRANSISTOR TECHNOLOGY.

22 NM IVY BRIDGE CHIP

TRADITIONAL PLANAR TRANSISTORS…

Microscopic view of 32nm transistor

MODIFICATIONS IN PLANAR TRANSISTORS…..

CHARACTERISTICS OF TRI-GATE TRANSISTORS…Reduction in

power dissipation

Increased pathway for

electrical signals

Drives 20% more current than

traditional planar transistors

High switching speed

High performance with reduced size

Better control over leakage current

due to 3D structure

TRI-GATE TRANSISTORS BENEFITS…

Dramatic performance gain at low operating voltage , better than Bulk, PDSOI,FDSOI37% performance increase at low voltage 50% power reduction at constant performanceImproved switching characteristics Higher drive current for a given transistorOnly 2 – 3% cost adder

Will it be the end of Processor era???

…Surely not!!!!!!

Because a new material is all set to replace semiconductors…

CONCLUSION :

THANK YOU..!
