1. 1. Closed-loop control and data- recording of a modular-multilevel converter (MMC)

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

   Författare :Longgang Su; [2022]
   Nyckelord :Modular multilevel converters MMCs ; filed programmable gate array FPGA ; direct memory access DMA ; energy closed-loop control; data recording; ethernet.; Modulära multilevel-omvandlare MMC ; filed programmeable gate array FPGA ; direkt minnesåtkomst DMA ; energistyrning med sluten slinga; datainspelning; ethernet.;

   Sammanfattning : Modular multilevel converters (MMCs) are the preferred converter solution in flexible ac transmission systems (FACTS) and high-voltage direct current (HVDC) applications. This is due to the high quality of the voltage and current signals, lower overall losses, and fewer problems with switching-related EMI. LÄS MER

3. 2. 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

4. 3. Ethernet DMA Datapath Performance Optimization for 5G Radios

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Saranya Balathandapani; Sunil Nanjiani; [2021]
   Nyckelord :DMA; Ethernet DMA; Technology and Engineering;

   Sammanfattning : Direct Memory Access (DMA) is a feature of computer systems that allows hardware subsystems to access the main memory of the system independent of the Central Processing Unit (CPU). With the rise of big data transfers from/to different I/O devices, the use of DMA controllers has increased significantly. LÄS MER

5. 4. OpenMZ: a C implementation of the MultiZone API

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

   Författare :Henrik Karlsson; [2020]
   Nyckelord :;

   Sammanfattning : We implemented, benchmarked, and analyzed OpenMZ, a separation kernel for RISC-V targeting secure coprocessors and embedded devices. OpenMZ is an open-source implementation of the MultiZone API, which partitions a system into a fixed number of zones that can communicate with each other and handle interrupts. LÄS MER

7. 5. DMA Support for Sancus Architecture

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

   Författare :Sergio Seminara; [2019]
   Nyckelord :;

   Sammanfattning : Computing devices have a predominant role in our lives, changing most of our daily activities. With the advent of the IoT, more and more embedded devices are expected to be connected, with expected numbers around 20 billion of units for the 2020. Nevertheless, the increase in connectivity does not imply an enhancement of security. LÄS MER
