We consider both logic and memory design aspects and cover modeling and analysis, as well as design methodology to achieve simultaneously low power and variation tolerance, while minimizing design overhead. This book will discuss current industrial practices and emerging challenges at future technology nodes.
Book Synopsis Adaptive Low-energy Techniques in Memory and Digital Signal Processing Design by : Ku He
Download or read book Adaptive Low-energy Techniques in Memory and Digital Signal Processing Design written by Ku He and published by . This book was released on 2012 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: As semiconductor technology continues to scale, energy-efficiency and power consumption have become the dominant design limitations, especially, for embedded and portable systems. Conventional worst-case design is highly inefficient from an energy perspective. In this dissertation, we propose techniques for adaptivity at the architecture and circuit levels in order to remove some of these inefficiencies. Specifically, this dissertation focuses on research contributions in two areas: 1) the development of SRAM models and circuitry to enable an intra-array voltage island approach for dealing with large random process variation; and 2) the development of low-energy digital signal processing (DSP) techniques based on controlled timing error acceptance. In the presence of increased process variation, which characterizes nanometer scale CMOS technology, traditional design strategies result in designs that are overly conservative in terms of area, power consumption, and design effort. Memory arrays, such as SRAM-based cache, are especially vulnerable to process variation, where the penalty is a power and bit-cell increase needed to satisfy a variety of noise margins. To improve yield and reduce power consumption in large SRAM arrays, we propose an intra-array voltage island technique and develop circuits that allow for a cost-effective deployment of this technique to reduce the impact of process variation. The voltage tuning architecture makes it possible to obtain, on average, power consumption reduction of 24% iso-area in the active mode, and the leakage power reduction up to 52%, and, on average, of 44% iso-area in the sleep mode. Alternatively, bitcell area can be reduced up to 50% iso-power compared to the existing design strategy. In many portable and embedded systems, signal processing (SP) applications are dominant energy consumers. In this dissertation we investigate the potential of error-permissive design strategies to reduce energy consumption in such SP applications. Conventional design strategies are aimed at guaranteeing timing correctness for the input data that triggers the worst-case delay, even if such data occurs infrequently. We notice that an intrinsic notion of quality floor characterizes SP applications. This provides the opportunity to significantly reduce energy consumption in exchange for a limited signal quality reduction by strategically accepting small and infrequent timing errors. We propose both design-time and run-time techniques to carefully control the quality-energy tradeoff under scaled VDD. The basic philosophy is to prevent signal quality from severe degradation, on average, by using data statistics. We introduce techniques for: 1) static and dynamic adjustment of datapath bitwidths, 2) design-time and run-time reordering of computations, 3) protection of important algorithm steps, and 4) exploiting the specific patterns of errors for low-cost post-processing to minimize signal quality degradation. We demonstrate the effectiveness of the proposed techniques on a 2D-IDCT/DCT design, as well as several digital filters for audio and image processing applications. The designs were synthesized using a 45nm standard cell library with energy and delay evaluated using NanoSim and VCS. Experiments show that the introduced techniques enable 40~70% energy savings while only adding less than 6% area overhead when applied to image processing and filtering applications.

Book Synopsis Towards an Ultra-Low Energy Computation with Asynchronous Circuits by : Tsung-Te Liu
Download or read book Towards an Ultra-Low Energy Computation with Asynchronous Circuits written by Tsung-Te Liu and published by . This book was released on 2012 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emerging biomedical applications would benefit from the availability of digital processors with substantially improved energy-efficiency. One approach to realize ultra-low energy processors is to scale the supply voltage aggressively to near or below the transistor threshold, yet the major increase in delay variability under process, voltage and temperature variations combined with the dominance of leakage power makes robust near- and sub-threshold computations and further voltage scaling extremely challenging. This research focuses on the design and implementation of robust and energy-efficient computation architectures by employing an asynchronous self-timed design methodology. A statistical framework is first presented to analyze the energy and delay of CMOS digital circuits considering a variety of timing methodologies. The proposed analysis framework combines variability and statistical performance models, which enables designers to efficiently evaluate circuit performance, and determine the optimal timing strategy, pipeline depth and supply voltage in the presence of variability. Two asynchronous self-timed designs are then implemented. First, a low-energy asynchronous logic topology using sense amplifier-based pass transistor logic (SAPTL) is presented. The SAPTL structure can realize very low energy computation by using low-leakage pass transistor networks at low supply voltages. The introduction of asynchronous operation in SAPTL further improves energy-delay performance without a significant increase in hardware complexity. The proposed self-timed SAPTL architectures provide robust and efficient asynchronous computation using a glitch-free protocol to avoid possible dynamic timing hazards. Second, an asynchronous neural signal processor is presented to dynamically minimize leakage and to self-adapt to process variations and different operating conditions. The self-timed processor demonstrates robust sub-threshold operation down to 0.25V, while consuming only 460nW in a 65nm CMOS technology, representing a 4.4X reduction in power compared to the state-of-the-art designs. The proposed asynchronous design approach enables CMOS circuits to fully benefit from continued technology scaling and realize ultra-low voltage operation, without incurring the leakage and variability issues associated with conventional synchronous implementations.
Book Synopsis Ultra-Low Energy Domain-Specific Instruction-Set Processors by : Francky Catthoor
Download or read book Ultra-Low Energy Domain-Specific Instruction-Set Processors written by Francky Catthoor and published by Springer. This book was released on 2010-08-22 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern consumers carry many electronic devices, like a mobile phone, digital camera, GPS, PDA and an MP3 player. The functionality of each of these devices has gone through an important evolution over recent years, with a steep increase in both the number of features as in the quality of the services that they provide. However, providing the required compute power to support (an uncompromised combination of) all this functionality is highly non-trivial. Designing processors that meet the demanding requirements of future mobile devices requires the optimization of the embedded system in general and of the embedded processors in particular, as they should strike the correct balance between flexibility, energy efficiency and performance. In general, a designer will try to minimize the energy consumption (as far as needed) for a given performance, with a sufficient flexibility. However, achieving this goal is already complex when looking at the processor in isolation, but, in reality, the processor is a single component in a more complex system. In order to design such complex system successfully, critical decisions during the design of each individual component should take into account effect on the other parts, with a clear goal to move to a global Pareto optimum in the complete multi-dimensional exploration space. In the complex, global design of battery-operated embedded systems, the focus of Ultra-Low Energy Domain-Specific Instruction-Set Processors is on the energy-aware architecture exploration of domain-specific instruction-set processors and the co-optimization of the datapath architecture, foreground memory, and instruction memory organisation with a link to the required mapping techniques or compiler steps at the early stages of the design. By performing an extensive energy breakdown experiment for a complete embedded platform, both energy and performance bottlenecks have been identified, together with the important relations between the different components. Based on this knowledge, architecture extensions are proposed for all the bottlenecks.
