1	Neutron Beam Testing Methodology and Results for a Complex Programmable Multiprocessor SoC Anderson, Jordan Daniel 01 March 2019 (has links) The Xilinx Multiprocessor System-on-Chip (MPSoC) is a complex device that uses 16nm FinFET technology to combine multiple processors, a large amount of FPGA resources, and many I/O interfaces on a single chip die. These features make the MPSoC a high-performance and architecturally flexible device. The potential computing power makes the MPSoC ideal for many embedded applications including terrestrial and space applications. The MPSoC, however, does not have extensive radiation history as many other devices have. The extent of the effect that ionized particles may have on the MPSoC is not well established. To solve this problem, neutron radiation testing can be used to determine the device's susceptibility to single-event upsets (SEUs). Though this thesis is not intended to qualify the MPSoC for space, this work does provide useful neutron radiation test data that helps to characterize the susceptible nature of the device. This thesis summarizes the SEU results obtained from neutron testing on the UltraScale+ MPSoC ZU9EG device. A series of three neutron beam tests were performed on the MPSoC ZU9EG at Los Alamos National Laboratories (LANL). Testing was performed using a novel testing methodology to collect SEU counts on the programmable logic and the processing system simultaneously. These results show a 10.1× improvement of the programmable logic CRAM over the previous Xilinx UltraScale device series.

3	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)
