PARALLEL PROCESSING AND PARALLEL PROCESSING

APPLICATIONS IN IMAGE PARAMETER

ABSTRACT

The science growth brings many problems with large volume of calculation, however, during a

certain time. The examples are 3D image processing problems, oil exploration, forecasting,

multiple-target follow-up system requiring fast computation speed, etc (sequential processing such

as von Neumann does not meet requirements). To solve these problems, it is researched to speed

up by two methods or a combination of two methods that are (1) technology improvement to

increase computer-processing speed, requiring more time, more expenses but brings speed limited

and (2) division of the problems into smaller tasks to run parallel on multiple processors

(functional decomposition problem). The most important principle of parallel processing is

simultaneity, or processing multiple tasks simultaneously. The paper generally studies about

parallel processing system and application of parallel processing problem in image parameters for

very good results and faster program

Keywords: parallel processing system; calculation; process multiple tasks simultaneously;

parallel processing image parameters, and increase processing speed.

INTRODUCTION*

Sequential computing with a processor carries

out only a computation in one time. However,

parallel processing can perform multiple

operations simultaneously. So it involves

many parameters, both hardware and

software. Figure 1 shows a comparison

between parallel programming and

conventional programming.

Developing control mechanisms of parallel

processing requires following components:

A-algorithm for parallel processing

(Algorithm); L - Language, O-Object Code;

M - Machine code

MULTI-CPUPARALLEL PROCESSING

SYSTEM

Multi-CPU system can be characterized by

two attributes: an independent processing

system including multiple CPUs and which

CPUs can contact and cooperate at various

degrees in performing assigned tasks.

Communication between CPUs performs by

notifying each other or sharing common

memory.
