  1. 6. Evaluation of cache memory configurations with performance monitoring in embedded real-time automotive systems : Determining performance characteristics of cache memory with hardware counters and software profiling.

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

    Author : Andreas Westman; [2022]
    Keywords : cache memory; real-time; hardware counters; automotive; cacheminne; realtid; hårdvaruräkare; fordon;

    Abstract : Modern day automotive systems are highly dependent on real-time software control to manage the powertrain and high-level features, such as cruise control. The computational power available has increased tremendously from decades of microcontroller and hardware development on such platforms. READ MORE

  3. 7. Security vs performance in a real-time separation kernel : An analysis for multicore RISC-V architecture

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

    Author : Henrik Kultala; [2022]
    Keywords : Separation kernel; RISC-V; Multicore; Real-time system; Performance analysis; Open-source; Separationskärna; RISC-V; Multicore; Realtidssystem; Prestandaanalys; Öppen källkod;

    Abstract : In this thesis, we explored the possibility of introducing a few vulnerabilities to a separation kernel to increase its performance. We made modifications to S3K, an open-source separation kernel that is in the final stages of being designed. READ MORE

  4. 8. Adaptive Frequency Resolution for Downlink Beamforming in 5G NR

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Johanna Bengtsson; [2021]
    Keywords : beamforming; MIMO; 5G; 5G NR; Technology and Engineering;

    Abstract : As the demand for higher data rates and lower latencies increase, together with the use of higher frequency bands, MIMO and beamforming have become an essential part of the 5G NR technology. Calculating the beamforming weights is a costly process, and reducing the frequency resolution of the weight calculations would save a significant amount of computational power. READ MORE

  5. 9. Predictable Multiprocessor Platform for Safety- Critical Real- Time Systems

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

    Author : Páll Axel Sigurðsson; [2021]
    Keywords : Composability; FPGA; Multicore processing; Predictability; Real- time systems; System on chip; FPGA; Förutsägbarhet; Komposibilitet; Mångkärnig bearbetning; Realtidssystem; System på chip;

    Abstract : Multicore systems excel at providing concurrent execution of applications, giving true parallelism where all cores can execute sequences of machine instructions at the same time. However, multicore systems come with their own sets of problems, most notably when cores in a system (or core tiles) share hardware components such as memory modules or Input/Output (IO) peripherals.

  6. 10. A Specification for Time-Predictable Communication on TDM-based MPSoC Platforms

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

    Author : Kelun Liu; [2021]
    Keywords : Communication; Time-Predictability; Network-on-Chip; Software Specification; Worst-Case Communication Time; Kommunikation; Tid Förutsägbarhet; Nätverk-på-Chip; MjukvaruSpecifikation; Kommunikationstid i Värsta Fall;

    Abstract : Formal System Design (ForSyDe) aims to bring the design of multiprocessor systems-on-chip (MPSoCs) to a higher level of abstraction and bridge the abstraction gap by transformational design refinement. The current research is focused on a correct-by-construction design flow, which requires design space exploration including formal models of computation and timepredictable platforms. READ MORE
