Principles of Asynchronous Circuit Design

Software Defined Radio (SDR) may provide flexible, upgradeable and longer lifetime radio equipment for the military and for civilian wireless communications infrastructure. SDR may also provide more flexible and possibly cheaper multi-standard-terminals for end users. It is also important as a convenient base technology for the future context-sensitive, adaptive and learning radio units referred to as cognitive radios. SDR also poses many challenges, however, some of them causing SDR to evolve slower than otherwise anticipated. Transceiver development challenges include size, weight and power issues such as the required computing capacity, but also SW architectural challenges such as waveform application portability. SDR has demanding implications for regulators, security organizations and business developers.

Software Defined Radio: Challenges and Opportunities

Bypass the limitations of synchronous design and create low power, higher performance circuits with shorter design times using this practical guide to asynchronous design. The fundamentals of asynchronous design are covered, as is a large variety of design styles, while the emphasis throughout is on practical techniques and real-world applications.

A Designer's Guide to Asynchronous VLSI

High-end mobile phones support multiple radio standards and a rich suite of applications, which involves advanced radio, audio, video, and graphics processing. The overall digital workload amounts to nearly 100GOPS, from 4b integer to 24b floating-point operations. With a power budget of only 1W this inevitably leads to heterogeneous multi-core architectures with aggressive power management. We review the state-of-the-art as well as trends.

Multi-core for mobile phones

Embedded systems architectures are increasingly becoming programmable, which means that an architecture can execute a set of applications instead of only one. This makes these systems cost-effective, as the same resources can be reused for another application by reprogramming the system. To design these programmable architectures, we present in this article a number of concepts of which one is the Y-chart approach. These concepts allow designers to perform a systematic exploration of the design space of architectures. Since this design space may be huge, it is narrowed down in a number of steps. The concepts presented in this article provide a methodology in which architectures can be obtained that satisfies a set of constraints while establishing enough flexibility to support a given set of applications.

A Methodology to Design Programmable Embedded Systems

'Design by programming' has proved very successful in the development of complex software systems. This book describes the construction of programs for VLSI digital circuit design, using the language Tangram, and shows how they can be compiled automatically in fully asynchronous circuits. Handshake circuits were invented by the author to separate questions involving the efficient implementation of the VLSI circuits from issues arising in their design. Dr van Berkel presents a mathematical theory of handshake circuits and a silicon compiler supported by a correctness proof. The treatment of VLSI realizations of handshake circuits includes various forms of optimization, handshake refinement, message encoding, circuit initialization, and testing. The approach is illustrated with a host of examples drawn from a wide range of application areas. The book will be of use to electrical engineers and computer scientists involved in VLSI design.

Handshake Circuits: An Asynchronous Architecture for VLSI Programming

In this paper we view VLSI design as a programming activity. VLSI designs are described in the algorithmic programming language Tangram. The paper gives an overview of Tangram, providing sufficient detail to invite the reader to try a small VLSI program himself. Tangram programs can be translated into handshake circuits, networks of elementary components that interact by handshake signaling. We have constructed a silicon compiler that automates this translation and converts these handshake circuits into asynchronous circuits and subsequently into VLSI layouts.

The VLSI-programming language Tangram and its translation into handshake circuits

A major challenge of software-defined radio (SDR) is to realize many giga operations per second of flexible baseband processing within a power budget of only a few hundred mW. A heterogeneous hardware architecture with the programmable vector processor EVP as key component can support WLAN, UMTS, and other standards. A detailed rationale for the EVP architecture, based on the analysis of a number of key algorithms, as well as implementation and benchmarking results are described.

Vector processing as an enabler for software-defined radio in handheld devices

In this chapter we analyze the potential of asynchronous circuits for low power consumption We set out by reviewing the mechanisms of energy dissipation of digital CMOS ICs in general and clocked circuits in particular For many applications the generation and distribution of the clock signal account for more than half the power dissipation, directly or indirectly Much of this wasted clock power — and often much more — can be saved by applying asynchronous circuit techniques

VLSI Programming of Asynchronous Circuits for Low Power

Handshake circuits form a special class of asynchronous circuits that has enabled the industrial exploitation of the asynchronous potential such as low power, low electromagnetic emission, and increased cryptographic security. In this paper we present a test solution for handshake circuits that brings synchronous test-quality to asynchronous circuits. We add a synchronous mode of operation to handshake circuits that allows full controllability and observability during test. This technique is demonstrated on some industrial examples and gives over 99% stuck-at fault coverage, using test-pattern generators developed for synchronous circuits. The paper describes how such a full-scan mode can be achieved, including an approach to minimize the number of dummy latches in case latches are used in the data path of the handshake circuit.
