Abstract

Video danas čini skoro 80% svih podataka na Internetu, te iz godine u godinu sve više raste. Transkodiranje je proces obrade videozapisa koji je veoma zahtjevan, što procesori opće namjene sve teže prate. Zbog toga se javlja potreba za ubrzavanjem dijelova pojedinih algoritama koristeći GPU ili FPGA kako bi se dobili bolji rezultati. U ovom radu izveden je sklop za ubrzanje u FPGA arhitekturi na pločici Virtex-7 koristeći MMI64 sučelje koji radi promjenu rezolucije videozapisa korištenjem algoritma „najbliži susjed“. Cilj rada je bilo ubrzanje, ali rezultat je ipak slično vrijeme izvođenja na obe arhitekture, uz dobru podlogu za daljnji napredak.

Abstract (english)

Today, video makes almost 80% of all data on Internet, and grows year after year. Transcoding is a process of video processing that is very demanding, which is for general purpose processors demanding algorithm. That is why there is a need to accelerate parts of algorithms using GPU or FPGA to get better results. In this work, an accelerator is implemented in the Virtex-7 using an MMI64 interface that performs change of video resolution using the "nearest neighbor" algorithm. The goal of the work was to accelerate, but the result is a similar time of execution on both architectures, with a good foundation for further progress.
