  1. 1. Evaluation of Memory Prefetching Techniques for Modem Applications

    Master-uppsats, Linköpings universitet/Datorteknik

    Författare :Gustav Nyholm; [2022]
    Nyckelord :cache; prefetching;

    Sammanfattning : Processor performance has increased far faster than memories have been able to keep up with, forcing processor designers to use caches in order to bridge the speed difference. This can increase performance significantly for programs that utilize the caches efficiently but results in significant performance penalties when data is not in cache. LÄS MER

  3. 2. Simulation of content-aware caching policies for tiled 360 videos

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Rami Latif; [2020]
    Nyckelord :content-aware; caching; policies; tiled; 360; video; streaming;

    Sammanfattning : Video streaming is used daily by people around the world, plays a big role in many Internet users daily lives, and are today responsible for the majority of the Internet traffic. As 360 video streaming services become increasingly popular and each such user session requires much higher bandwidths than traditional video streaming, optimized solutions for this type of video is becoming increasingly important.

  4. 3. Store prefetch policies : Analysis and new proposals

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Carl Boström; [2018]
    Nyckelord :;

    Sammanfattning : This thesis is focusing on how to gain performance when executing programs on a CPU. More specifically the store instructions are studied. These instructions often cause huge delays while waiting on write per- mission for a particular data block. LÄS MER

  5. 4. Multi-Video Streaming with DASH

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Markus Johansson; Sebastian Andersson; [2017]
    Nyckelord :DASH; multi-video; dash.js; prefetch; Dynamic Adaptive Streaming over HTTP;

    Sammanfattning : Multi-video streaming allows the viewer to interact with the stream by choosing andswitching between several different camera angles to view the stream from. For this reportwe implement and evaluate adaptive multi-video streaming with dash.js. With the help ofdash. LÄS MER

  7. 5. HTTP/2, Server Push and Branched Video : Evaluation of using HTTP/2 Server Push in Dynamic Adaptive Streaming over HTTP with linear and non-linear prefetching algorithms

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Summia Al-mufti; Rasmus Jönsson; [2017]
    Nyckelord :HTTP 2; Server Push; Branched video; Dynamic Adaptive Streaming over HTTP; DASH;

    Sammanfattning : The purpose of this thesis is to investigate and test the usage of HTTP/2 in dynamic adaptive video streaming as well as to take a look into how it can be used to benefit prefetching algorithms used with branched video. With a series of experiments the performance gains of using HTTP/2 rather than the older standard HTTP/1.1 has been investigated. LÄS MER
