Until now, there has been a lack of a complete knowledge base to fully comprehend Low power (LP) design and power aware (PA) verification techniques and methodologies and deploy them all together in a real design verification and implementation project. This book is a first approach to establishing a comprehensive PA knowledge base. LP design, PA verification, and Unified Power Format (UPF) or IEEE-1801 power format standards are no longer special features. These technologies and methodologies are now part of industry-standard design, verification, and implementation flows (DVIF). Almost every chip design today incorporates some kind of low power technique either through power management on chip, by dividing the design into different voltage areas and controlling the voltages, through PA dynamic and PA static verification, or their combination. The entire LP design and PA verification process involves thousands of techniques, tools, and methodologies, employed from the r egister transfer level (RTL) of design abstraction down to the synthesis or place-and-route levels of physical design. These techniques, tools, and methodologies are evolving everyday through the progression of design-verification complexity and more intelligent ways of handling that complexity by engineers, researchers, and corporate engineering policy makers.

Managing the power consumption of circuits and systems is now considered one of the most important challenges for the semiconductor industry. Elaborate power management strategies, such as dynamic voltage scaling, clock gating or power gating techniques, are used today to control the power dissipation during functional operation. The usage of these strategies has various implications on manufacturing test, and power-aware test is therefore increasingly becoming a major consideration during design-for-test and test preparation for low power devices. This book explores existing solutions for power-aware test and design-for-test of conventional circuits and systems, and surveys test strategies and EDA solutions for testing low power devices.

The goal of this project was to take DoD applications written in C and generate power and performance efficient code for systems utilizing the architectural power-aware techniques developed. The PACT project consisted of 3 research tasks: 1) Power-aware architectural approaches, 2) Power-aware compilation strategies, and 3) Power-aware CAD tools for power estimation and synthesis. As part of the power aware architecture research, we developed power aware techniques for on-chip buses, power aware memory hierarchies, and a framework to evaluate heterogeneous embedded systems for performance and energy consumption. As part of the power aware compiler research, we have developed a compiler that takes general C programs and generates power aware codes for three targets: 1) General purpose embedded processor such as the StrongARM, 2) General purpose field-programmable gate arrays (FPGAs), and 3) General purpose application specific integrated circuits (ASICs). We have developed improved strategies for power optimization and management, and improved design methodologies and design philosophies for better estimation and optimization.

Design exibility and power consumption in addition to the cost, have always been the most important issues in design of integrated circuits (ICs), and are the main concerns of this research, as well. Energy Consumptions: Power dissipation (P ) and energy consumption are - diss pecially importantwhen there is a limited amountof power budgetor limited source of energy. Very common examples are portable systems where the battery life time depends on system power consumption. Many different techniques have been - veloped to reduce or manage the circuit power consumption in this type of systems. Ultra-low power (ULP) applications are another examples where power dissipation is the primary design issue. In such applications, the power budget is so restricted that very special circuit and system level design techniquesare needed to satisfy the requirements. Circuits employed in applications such as wireless sensor networks (WSN), wearable battery powered systems [1], and implantable circuits for biol- ical applications need to consume very low amount of power such that the entire system can survive for a very long time without the need for changingor recharging battery[2–4]. Using newpowersupplytechniquessuchas energyharvesting[5]and printable batteries [6], is another reason for reducing power dissipation. Devel- ing special design techniques for implementing low power circuits [7–9], as well as dynamic power management (DPM) schemes [10] are the two main approaches to control the system power consumption. Design Flexibility: Design exibility is the other important issue in modern in- grated systems.

Automated Power-aware System-level Design with the MAVO Framework

For the past few decades, semiconductor capabilities have been improving as Moore's law predicted. Transistor size has been shrinking and technology size will be less than 20nm in the near future. These improvements enable designers to come up with more complex systems. However, this has made power dissipation a major design obstacle. Conventionally, power consumption is considered in the later stages of the design process, like the architecture level, Register Transfer Level (RTL), gate level, and physical level, where detailed information about the design is available. Although there are many power-aware design tools at these lower levels, the simulation and evaluation time are high and often beyond the time-to-market requirements. To tackle the long simulation time as well as avoiding time consuming design modifications at lower levels, designers are raising the level of abstraction to the system level. Over the last decade, research in Electronic System Level (ESL) design has resulted in significant advances in addressing the rising design complexity and meeting the required performance constraints. Now a major concern of system-level design is power dissipation in System-on-Chip (SoC) which not only affects battery lifetime but also thermal aspects and reliability of the end product. Although power aware design is crucial in ESL design, System Level Description Languages (SLDL) are not supporting this feature natively. Towards power-aware ESL design, in this dissertation we present MAVO, an automated framework to Monitor, Analyze, Visualize and Optimize both power and performance at the early stages of the design process. The proposed framework supports waveform-based power estimation and optimization for rapid system-level design. MAVO is adapted for automated SoC design and it is integrated to System-on-Chip Environment, a prototype ESL design tool for rapid power-aware design. We perform different experiments to evaluate the accuracy and fidelity of the framework, including JPEG image encoder, MP3 audio decoder and H.264 video decoder and encoder. Experimental results show that our developed framework can achieve a high degree of fidelity while providing significant speedup. We also examined MAVO for applying different power optimization mechanisms on a Canny edge detector application. Our studies show large potential for design modification toward power efficient design models at system-level. Additionally we applied MAVO along with static analyzer tool in order to capture power and performance trade-offs and apply power optimization techniques automatically. Overall, our work provides an advanced power estimation infrastructure for power- and performance-aware system model development. It can significantly help embedded system designers to build low-power and reliable products in shorter time frame.

View: 761

Dr Donald Bailey starts with introductory material considering the problem of embedded image processing, and how some of the issues may be solved using parallel hardware solutions. Field programmable gate arrays (FPGAs) are introduced as a technology that provides flexible, fine-grained hardware that can readily exploit parallelism within many image processing algorithms. A brief review of FPGA programming languages provides the link between a software mindset normally associated with image processing algorithms, and the hardware mindset required for efficient utilization of a parallel hardware design. The design process for implementing an image processing algorithm on an FPGA is compared with that for a conventional software implementation, with the key differences highlighted. Particular attention is given to the techniques for mapping an algorithm onto an FPGA implementation, considering timing, memory bandwidth and resource constraints, and efficient hardware computational techniques. Extensive coverage is given of a range of low and intermediate level image processing operations, discussing efficient implementations and how these may vary according to the application. The techniques are illustrated with several example applications or case studies from projects or applications he has been involved with. Issues such as interfacing between the FPGA and peripheral devices are covered briefly, as is designing the system in such a way that it can be more readily debugged and tuned. Provides a bridge between algorithms and hardware Demonstrates how to avoid many of the potential pitfalls Offers practical recommendations and solutions Illustrates several real-world applications and case studies Allows those with software backgrounds to understand efficient hardware implementation Design for Embedded Image Processing on FPGAs is ideal for researchers and engineers in the vision or image processing industry, who are looking at smart sensors, machine vision, and robotic vision, as well as FPGA developers and application engineers. The book can also be used by graduate students studying imaging systems, computer engineering, digital design, circuit design, or computer science. It can also be used as supplementary text for courses in advanced digital design, algorithm and hardware implementation, and digital signal processing and applications.
