A High-SpeedLow-Power Multiplier Using an Advanced Spurious Power Suppression Technique


Abstract”
This study provides the experience of applying an advanced version of our former Spurious Power Suppression Technique (SPST) on multipliers for high-speed and low-power purposes. To filter out the useless switching power, there are two approaches, i.e. using registers and using AND gates, to assert the data signals of multipliers after the data transition. The simulation results show that the SPST implementation wit ....etc

Abstract:

This project provides the experience of applying an advanced version of Spurious Power Suppression Technique (SPST) on multipliers for high speed and low power purposes. When a portion of data does not affect the final computing results, the data controlling circuits of SPST latch this portion to avoid useless data transition occurring inside the arithmetic units, so that the useless spurious signals of arithmetic units are filter out. Modified Booth Algorithm is used in this project for mul ....etc

An image defined in the real world is considered to be a function of two real variables say x,y.
Before going to processing an image, it is converted into a digital form. Digitization includes sampling of image and quantization of sampled values.
After converting the image into bit information, processing is performed.
This processing technique may be,
Image enhancement
Image reconstruction
Image compression
Image enhancement refers to accentuation, or sharpening, of image features such as boundaries.
Image restoration is con ....etc

INTRODUCTION
 Speech coding is defined as a digital representation of the speech signal .
 Speech compression is achieved by representing each sample of digitized data by lesser number of bits.
 In compression technique the 13 to 16 bits data is represented by an equivalent of 4 or 8 bits.
 In decompression technique the compressed data is converted back to original data.

This seminarsr provides the experience of applying an advanced version of our former spurious power suppression technique (SPST) on multipliers for high-speed and low-power purposes. To filter out the useless switching power, there are two approaches, i.e., using registers and using AND gates, to assert the data signals of multipliers after the data transition. The SPST has been applied on both the modified Booth decoder and the compression tree of multipliers to enlarge the power reduction. The simulation results show that the SPST implementat ....etc

MPEG-2 VIDEO COMPRESSION TECHNIQUE

Abstract:
MPEG-2 is an extension of the MPEG-1 nternational standard for digital compression of audio and video signals.MPEG-1 was designed to code progressively scanned video at bit rates up to about 1.5 Mbit/s for applications such as CD-I (compact disc interactive). MPEG-2 is directed at broadcast formats at higher data rates; it provides extra algorithmic tools' for efficiently coding interlaced video supports a wide range of bit rates and provides ....etc
