Abstract

Završni rad se temelji na korištenju ARM NEON naredbi kako bi se
optimirao JPEG algoritam. JPEG algoritam je algoritam koji se koristi za sažimanje
fotografija na način da naizgled ne gubimo nikakve informacije. Ovaj rad je pisan u
programskom jeziku C.
Kroz nekoliko poglavlja su opisani svi bitni sadržaji vezani uz ovu temu. Na
početku je opisano ljudsko oko, njegove funkcije i svojstva i na koji način je to
moguće iskoristiti za sažimanje fotografije a da ljudsko oko ne prepoznaje da je
odbačen dio informacija. Zatim su opisani koraci JPEG algoritma i objašnjenje
principa rada ARM NEON naredbe.
U središnjem dijelu ovog završnog rada se objašnjava na koji konkretan
način sam ubrzao algoritam koristeći ARM NEON naredbe.
Na kraju se nalaze upute za instalaciju i korištenje ovog optimiranog JPEG
kodera.

Abstract (english)

This work describes JPEG algorithm implementation using the ARM NEON
instructions. JPEG algorithm is an algorithm that is used in lossy compression of
the pictures. This work has been written in C programming language.
Through several chapters, all important contents connected to this topic,
are described . At the very beginning, human eye is described, its functions,
properties and a way in which we can compress photos, but with a fact that human
eye can not recognize that we discarded part of the information. Afterwards, steps
of JPEG algorithm are described, including explanations of work principles of
ARM NEON command.
In the central part of this discussion it has been explained the way in which
we accelerated our algorithm using the ARM NEON commands.
At the end there are instructions for installing and using this optimized
JPEG coder.
