  2. 1. Low-Power Low-Jitter Clock Generation and Distribution

    Author : Behzad Mesgarzadeh; Atila Alvandpour; Thucydides Xanthopoulos; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-power; resonant clock distribution; injection locking; DLL-based clock generation; jitter suppression; CMOS; Electronics; Elektronik;

    Abstract : Today’s microprocessors with millions of transistors perform high-complexitycomputing at multi-gigahertz clock frequencies. Clock generation and clockdistribution are crucial tasks which determine the overall performance of amicroprocessor. READ MORE

  4. 2. The circadian clock in annuals and perennials : coordination of Growth with Environmental Rhythms

    Author : Mikael Johansson; Maria E. Eriksson; Paul Devlin; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; circadian clock; arabidopsis; populus; Molecular biology; Molekylärbiologi; Plant biotechnology; Växtbioteknik; Plant physiology; Växtfysiologi; molekylärbiologi; Molecular Biology;

    Abstract : Since the first signs of life on planet earth, organisms have had to adapt to the daily changes between light and dark, and high and low temperatures. This has led to the evolution of an endogenous time keeper, known as the circadian clock. READ MORE

  5. 3. Improving Clock Synchronization Performance in Industrial Networks

    Author : Rahul Nandkumar Gore; Elena Lisova; Johan Åkerberg; Mats Björkman; Han Song; Mälardalens universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Clock synchronization; Industrial networks; Internet of things; Industry 4.0; Network Calculus; Computer Science; datavetenskap;

    Abstract : The recent advances in cyber-physical systems and industrial internet-of-things (IIoT) have enabled the convergence of information technology (IT) and operational technology (OT) worlds of industrial automation systems achieving higher productivity, reliability, and revenues. The availability of business-critical and production-critical data on the converged network has enabled new and advanced network-centric applications that require time-constrained embedded devices to be connected to “the internet.

  6. 4. Investigating Software-based Clock Synchronization for Industrial Networks

    Author : Rahul Nandkumar Gore; Mats Björkman; Johan Åkerberg; Elena Lisova; Henrik Lönn; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Clock synchronization; Industrial networks; Internet of things; Industry 4.0; Computer Science; datavetenskap;

    Abstract : A rising level of industrialization and advances in Industry 4.0 have resulted in Industrial Internet of Things (IIoT) gaining immense significance in today’s industrial automation systems. IIoT promises to achieve improved productivity, reliability, and revenues by connecting time-constrained embedded systems to “the Internet”. READ MORE

  7. 5. Contributions to Asynchronous Communication Ports for GALS Systems

    Author : Jonas Carlsson; Juha Plosila; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GALS; Asynchronous; Asynchronous communication ports; Clock gating; Clock domains; Electronics; Elektronik;

    Abstract : Digital systems commonly use a single global clock signal to synchronize the whole system. This is not always possible and it can be more advantageously to divide the system into separate clock domains, where each clock domain can operate with its own clock frequency. READ MORE
