Abstract

Ovaj rad opisuje upotrebu gem5 diskretne platforme za simulaciju računalnih sustava te u detalje objašnjava proces oblikovanja sustava za simulaciju koji koristi računalne komponente specifičnih karakteristika. Rad nastoji putem gem5 platforme simulirati kontrolni sustav što točnije modeliran po postojećem procesoru ARMv8 arhitekture naziva Cortex-A34 te zatim mijenjajući ključne karakteristike tog sustava analizira utjecaj pojedinih parametara na procese obrade video sekvenci korištenjem aplikacije za obrade video sadržaja FFmpeg. Na temelju rezultata brojnih simulacija s različitim parametrima rad iznosi zaključke o važnosti pojedinih računalnih komponenata te predlaže vrijednosti parametara sustava za što efikasniju obradu video zapisa.

Abstract (english)

This paper describes the usage of the gem5 discrete platform for computer system simulation and it clarifies to an extent the process of designing simulation systems that use computer components with specific characteristics. The paper attempts to simulate a control system that emulates the real world ARMv8 architecture Cortex-A34 processor to a very close degree of similarity to then use as a reference point for many simulations with differing key characteristics in an effort to analyse the effect of certain parameters on the efficiency of video encoding and editing processes performed by the video editing software FFmpeg. Based on the results of the numerous simulations with different parameters the paper brings forth conclusions on the importance of specific computer components and suggests parameter values for the most efficient video editing procedures.
