  1. 1. Dynamic Torque Control of Brushed DC Motors for Hardware-in-the-Loop Integration

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Eric Schyllert; [2023]
    Keywords : Technology and Engineering;

    Abstract : The main goal with the thesis was to design, construct and evaluate a system able to drive and brake a mechanical axis to simulate loads and stored rotational energy - a hardware force simulator. The force simulator was then to be integrated in a existing hardware-in-the-loop testing rig to enhance the mechanical dynamics of door simulations. READ MORE

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

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

    Author : Longgang Su; [2022]
    Keywords : 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.;

    Abstract : 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. READ MORE

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

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

    Author : Saranya Balathandapani; Sunil Nanjiani; [2021]
    Keywords : DMA; Ethernet DMA; Technology and Engineering;

    Abstract : 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. READ MORE

  5. 4. Formal Verification of Hardware Peripheral with Security Property

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Jonathan Yao Håkansson; Niklas Rosencrantz; [2017]
    Keywords : Formal Verification NuSMV JavaPathFinder Spin Promela CTL LTL DMA UART Model Checking Theorem Proving;

    Abstract : One problem with computers is that the operating system automatically trusts any externallyconnected peripheral. This can result in abuse when a peripheral technically can violate the security model because the peripheral is trusted. Because of that the security is an important issue to look at. READ MORE

  6. 5. DMA Controller for LEON3 SoC:s Using AMBA

    University essay from Datorteknik; Tekniska högskolan

    Author : Emelie Nilsson; [2013]
    Keywords : AHB; AMBA; APB; DMA; LEON3;

    Abstract : A DMA Controller can offload a processor tremendously. A memory copy operation can be initiated by the processor and while the processor executes others tasks the memory copy can be fulfilled by the DMA Controller. An implementation of a DMA Controller for use in LEON3 SoC:s has been made during this master thesis. READ MORE
