1	Portning av ett Linuxbaserat system / Porting of a Linux based system Johansson, Anton, Stenzelius, Kalle January 2022 (has links) The project is about embedded systems in self-driving vehicles which is a growing andcurrent area. This is important as the automation of vehicles can make different sectorssuch as the mining and logistics industry more effective. This work relates to the topicas it aims to improve part of the self-driving software stack by replacing Ubuntu with aless resource-intensive Linux based system. The main goal of this work is to implementand document improvements. The work contains a research part where advantages anddisadvantages are compared against each other, followed by an implementation thatiteratively solved one problem at a time.The result became instructions and documentation describing the choices madefor a less resource demanding Linux based system. It also includes instructions anddocumentation for two different application that are part of the software stack. / Projektet handlar om inbyggda system i självkörande fordon vilket är ett växande ochaktuellt område. Det är viktigt då automatiseringen av fordon kan effektivisera mångaolika sektorer som till exempel gruv- och logistikindustrin. Detta arbete relaterar tillämnet då det har som mål att effektivisera en del av den självkörande mjukvarustackengenom att byta ut Ubuntu till ett mindre resurskrävande Linux-system. Huvudmålet meddetta arbete är att implementera och dokumentera förbättringar. Arbetet innehåller en ut-redningsdel där för- och nackdelar jämförs mot varandra följt av en implementationsdelsom iterativt hanterar ett problem i taget.Resultatet blev instruktioner och dokumentation över de val som tagits för ett mindreresurskrävande Linux-system samt instruktioner och dokumentation över två applikatio-ner som är en del av mjukvarustacken. yocto linux petalinux xilinx embedded system zcu102 ultrascale ultrascale+ zynq yocto linux petalinux xilinx inbyggt system zcu102 ultrascale ultrascale+ zynq Computer Systems Datorsystem Computer and Information Sciences Data- och informationsvetenskap Computer Sciences Datavetenskap (datalogi)
2	Analýzy síťového provozu na procesoru NXP a FPGA / Network Traffic Analysis Using NXP Processor and FPGA Orsák, Michal January 2018 (has links) The primary goal of this thesis is to exploit possibilites of aa entirely new hardware based on NXP LS2088 and FPGA. The secondary goal is to create firmware for this processor working out-of-box and perform optimisations of existing software for L7 analysis. This software was deeply bound to a previous hardware platform. The network processor NXP LS2088 contains many hardware accellerators and a virtual reconfigurable network. This thesis exploits all hardware parts of on this platform. Many tweaks and optimizations were performed based on this analysis to achieve maximum efficieny of software for L7 analysis. There were many intensive optimisations like rewriting for the DPDK library and new hardware or hardware synchronization of worker threads of this application. The main result of this thesis is working platform with efficient L7 analysis software which actively uses accelerators in FPGA and NXP network processor. SDK for new platform is also prepared.
