1. 1. Predictable Multiprocessor Platform for Safety- Critical Real- Time Systems

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

   Sammanfattning : 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.

3. 2. Analysis of the performance of Hybrid TWDM Passive OpticalNetworks (NG-PON2)

   Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

   Författare :Rameez Ahmed Khan; [2021]
   Nyckelord :Next Generation Passive Optical Networks NG-PONS ; Time Division Multiplexing TDM ; Wavelength Division Multiplexing WDM ; Hybrid Passive Optical Networks; Time and Wavelength Division Passive Optical Networks TWDM PON ;

   Sammanfattning : In this study, a review of research literature has been carried out to investigate Hybrid Time and wavelength Division Multiplexing techniques with respect to reach, split ratio, and speed of the network. This was done to overcome challenges presented by Passive Optical Networks, such as the reach and the high split ratio. LÄS MER

4. 3. A Specification for Time-Predictable Communication on TDM-based MPSoC Platforms

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

   Sammanfattning : 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. LÄS MER

5. 4. Dataöverföring av skilda datatyper på gemensam länk via multiplexing

   Kandidat-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

   Författare :Edvin Andersson; [2017]
   Nyckelord :TDM; Time Division Multiplexing; Multiplexing; Dataförlust;

   Sammanfattning : När olika datatyper överförs mellan två platser har, historiskt sett, detta skett på skildinfrastruktur; analoga signaler för sig, och digitala data för sig. Inom flygindustrin hanteras båda dessa datatyper än idag, då övergång från analoga röstsamtal till digitala röstsamtal tar tid. LÄS MER

7. 5. Hybrid Power Control in Time Division Scheduling Wideband Code Division Multiplex Access

   Master-uppsats, KTH/Kommunikationssystem, CoS

   Författare :Zhuo Cheng; [2011]
   Nyckelord :WCDMA; High-Speed Uplink Packet Access; Power Control; unused code GRAKE;

   Sammanfattning : With high date rates using Enhanced Uplink (EUL), a conventional signal to interference ratio (SIR) based power control algorithm may lead to a power rush due to self interference or incompatible SIR target [2]. Time division (TD) scheduling in Wideband Code Division Multiplex Access (WCDMA) is considered to be a key feature in achieving high user data rates. LÄS MER
