Wir alle wissen,dass die Embedded-Elektronik mittlerweile prak- tisch überall zu finden ist: von der Waschmaschine bis zur Büro- beleuchtung, von der Maschinensteuerung bis zum Computer- tomographen etc. Eigentlich hat sich an der klassischen Aufgabenstellung von Embedded-Systemen über all die Jahre hinweg praktisch nichts geändert,denn stets heißt es,Eingangs- größen zu verarbeiten und am Ausgang entsprechende (An- steuerungs-)Signale zur Verfügung zu stellen, wobei zugegebe- nermaßen die Komplexität derartiger Systeme gewaltig zugenommen hat.

  • Optimization of Clock Gating Logic for Low Power LSI Design
    Optimization of Clock Gating Logic for Low Power LSI Design Xin MAN September 2012 Waseda University Doctoral Dissertation Optimization of Clock Gating Logic for Low Power LSI Design Xin MAN Graduate School of Information, Production and Systems Waseda University September 2012 Abstract Power consumption has become a major concern for usability and reliability problems of semiconductor products, especially with the significant spread of portable devices, like smartphone in recent years. Major source of dynamic power consumption is the clock tree which may account for 45% of the system power, and clock gating is a widely used technique to reduce this portion of power dissipation. The basic idea of clock gating is to reduce the dynamic power consumption of registers by switching off unnecessary clock signals to the registers selectively depending on the control signal without violating the functional correctness. Clock gating may lead to a considerable power reduction of overall system with proper control signals. Since the clock gating logic consumes chip area and power, it is imperative to minimize the number of inserted clock gating cells and their switching activity for power optimization. Commercial tools support clock gating as a power optimization feature based on the guard signal described in HDL and the minimum number of registers injecting the clock gating cell specified as the synthesis option (structural method). However, this approach requires manual identification of proper control signals and the proper grouping of registers to be gated. That is hard and designer-intensive work. Automatic clock gating generation and optimization is necessary. In this dissertation, we focus on the optimization of clock gating logic i ii based on switching activity analysis including clock gating control candidate extraction from internal signals in the original design and optimum control signal selection considering sharing of a clock gating cell among multiple registers for power and area optimization.

  • Mutual Impact Between Clock Gating and High Level Synthesis in Reconfigurable Hardware Accelerators
    electronics Article Mutual Impact between Clock Gating and High Level Synthesis in Reconfigurable Hardware Accelerators Francesco Ratto 1 , Tiziana Fanni 2 , Luigi Raffo 1 and Carlo Sau 1,* 1 Dipartimento di Ingegneria Elettrica ed Elettronica, Università degli Studi di Cagliari, Piazza d’Armi snc, 09123 Cagliari, Italy; [email protected] (F.R.); [email protected] (L.R.) 2 Dipartimento di Chimica e Farmacia, Università degli Studi di Sassari, Via Vienna 2, 07100 Sassari, Italy; [email protected] * Correspondence: [email protected] Abstract: With the diffusion of cyber-physical systems and internet of things, adaptivity and low power consumption became of primary importance in digital systems design. Reconfigurable heterogeneous platforms seem to be one of the most suitable choices to cope with such challenging context. However, their development and power optimization are not trivial, especially considering hardware acceleration components. On the one hand high level synthesis could simplify the design of such kind of systems, but on the other hand it can limit the positive effects of the adopted power saving techniques. In this work, the mutual impact of different high level synthesis tools and the application of the well known clock gating strategy in the development of reconfigurable accelerators is studied. The aim is to optimize a clock gating application according to the chosen high level synthesis engine and target technology (Application Specific Integrated Circuit (ASIC) or Field Programmable Gate Array (FPGA)). Different levels of application of clock gating are evaluated, including a novel multi level solution. Besides assessing the benefits and drawbacks of the clock gating application at different levels, hints for future design automation of low power reconfigurable accelerators through high level synthesis are also derived.

    WHITE PAPER CREATING LOW-POWER DIGITAL INTEGRATED CIRCUITS – THE IMPLEMENTATION PHASE INTRODUCTION Power consumption has now moved to the forefront of digital integrated circuit (IC) development con- cerns. The combination of higher clock speeds, greater functional integration, and smaller process geometries has contributed to significant growth in power density. Furthermore, with every new pro- cess generation, leakage power consumption increases at an exponential rate. In recent years, a wide variety of techniques have been developed to address the various aspects of the power problem and to meet ever more aggressive power specifications. These techniques include clock gating, multi-switching threshold (multi-Vt) transistors, multi-supply multi-voltage (MSMV), substrate biasing, dynamic voltage and frequency scaling (DVFS), and power shut-off (PSO). Figure 1 illustrates the power, timing, and area tradeoffs among the various power management techniques.

Tradeoffs associated with the various power management techniques Notably, designers cannot simply “bolt on” low power” at the end of the development process. The size and complexity of today’s ICs makes it imperative to consider power throughout the design phases—the chip/system architecture, power architecture, and design (including micro-architecture decisions)—and all the way to implementation with power-aware synthesis, placement, and routing.

Algorithms for the Discrete Cosine Transform (DCT) and its inverse are introduced which exploit sta- tistical properties of the input data in both the space and spatial frequency domains in order to minimize the total number of arithmetic operations. Two VLSI chips have been built as a proof-of-concept of data dependent processing implementing the DCT and its inverse (IDCT). The IDCT core processor exploits the presence of a large number of zero- valued spectral coefficients in the input stream when stimulated with MPEG-compressed video sequences.

  • Physically Constrained Architecture for Chip Multiprocessors
    Physically Constrained Architecture for Chip Multiprocessors A Dissertation Presented to the faculty of the School of Engineering and Applied Science University of Virginia In Partial Fulfillment of the requirements for the Degree Doctor of Philosophy Computer Science by Yingmin Li August 2006 c Copyright August 2006 Yingmin Li All rights reserved Approvals This dissertation is submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy Computer Science Yingmin Li Approved: Kevin Skadron (Advisor) Jack W. Davidson (Chair) Mircea R. Stan David M. Brooks Sudhanva Gurumurthi Accepted by the School of Engineering and Applied Science: James H. Aylor (Dean) August 2006 Abstract Recent product announcements show a clear trend towards aggressive integration of multiple cores on a single chip. This kind of architecture is called a “chip multiprocessor” or CMP. By taking advantage of thread level parallelism, CMP can achieve better performance/power scalability with technology than single core architectures. However, this trend presents an expansive design space for chip architects, encompassing number of cores per die, core size and complexity (pipeline depth and superscalar width), core type (in-order and out-of-order, single-threaded or multi-threaded), memory hierarchy and interconnection fabric design, operating voltage and frequency, and so on. These choices are especially difficult because all the variables of interest are inter-related and must be considered simultaneously. Furthermore, trade-offs among these design choices vary depending both on workloads and physical constraints like power, area and thermal constraints. Ignoring any of these physical constraints at early design stage may lead to significant performance loss.
