  1. 1. An evaluation of eXpress Data Path from a 5G perspective : Offloading packet processing functions of a 5G simulator to a driver context

    University essay from Linköpings universitet/Databas och informationsteknik

    Author : Adrian Byström; Mattias Salo; [2022]
    Keywords : XDP; DPDK; 5G; computer networks; Linux; eXpress Data Path; eBPF; packet processing; XDP; DPDK; 5G; datornätverk; Linux; eXpress Data Path; eBPF; paketprocessering;

    Abstract : The world of computer networks is constantly evolving towards more efficient algorithms and more effective ways of using hardware resources. One of these evolutions is the eXpress Data Path (XDP). XDP is an interrupt based data path in the Linux kernel. XDP uses JIT-compiled programs in a virtual machine in a device driver context.

  3. 2. Formal verification of device driver monitors in HOL 4

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Tomas Möre; [2021]
    Keywords : ;

    Abstract : As computer systems become more ubiquitous in society the negative consequences of security holes and bugs in software and hardware grow larger. In theory, the optimal way to ensure that no such possibilites exists is to conduct formal proofs that the system behaves as it should and that it is incapable of performing unintended side-effects.

    Abstract : Professional audio processing systems such as digital musical instruments, audiomixers, etc. must operate with very tight constraints on overall processing latencyand CPU performance. READ MORE

  5. 4. Graphics System in Vehicle Electronics

    University essay from Institutionen för informationsteknologi

    Author : Andreas Kjellgren; [2009]
    Keywords : ;

    Abstract : In this thesis three problems areas are studied related to embedded system and device driver programming: a GPS driver, the CAN Bus and study of graphics libraries suitable for embedded systems. The thesis has two parts: an academic study and an implementation phase based on the academic study. The Freescale i. READ MORE

  6. 5. An FPGA Based Software/Hardware Codesign for Real Time Video Processing : A Video Interface Software and Contrast Enhancement Hardware Codesign Implementation using Xilinx Virtex II Pro FPGA

    University essay from Institutionen för systemteknik

    Author : Jian Wang; [2006]
    Keywords : Hardware and software codesign; embedded Linux; video4linux; custom IPcore; noise reduction; contrast enhancement;

    Abstract : Xilinx Virtex II Pro FPGA with integrated PowerPC core offers an opportunity to implementing a software and hardware codesign. The software application executes on the PowerPC processor while the FPGA implementation of hardware cores coprocess with PowerPC to achieve the goals of acceleration. READ MORE
