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.

Download or read book Completion Detection in Asynchronous Circuits written by Pallavi Srivastava and published by Springer Nature. This book was released on 2022-11-08 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended for designers with experience in traditional (clocked) circuit design, seeking information about asynchronous circuit design, in order to determine if it would be advantageous to adopt asynchronous methodologies in their next design project. The author introduces a generic approach for implementing a deterministic completion detection scheme for asynchronous bundled data circuits that incorporates a data-dependent computational process, taking advantage of the average-case delay. The author validates the architecture using a barrel shifter, as shifting is the basic operation required by all the processors. The generic architecture proposed in this book for a deterministic completion detection scheme for bundled data circuits will facilitate researchers in considering the asynchronous design style for developing digital circuits.
Download or read book Ultra low Power and Radiation Hardened Asynchronous Circuit Design written by Liang Zhou and published by . This book was released on 2012 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation proposes an ultra-low power design methodology called bit-wise MTNCL for bit-wise pipelined asynchronous circuits, which combines multi-threshold CMOS (MTCMOS) with bit-wise pipelined NULL Convention Logic (NCL) systems. It provides the leakage power advantages of an all high-Vt implementation with a reasonable speed penalty compared to the all low-Vt implementation, and has negligible area overhead. It was enhanced to handle indeterminate standby states. The original MTNCL concept was enhanced significantly by sleeping Registers and Completion Logic as well as Combinational circuits to reduce area, leakage power, and energy per operation. This dissertation also develops an architecture that allows NCL circuits to recover from a Single Event Upset (SEU) or Single Event Latchup (SEL) fault without any data loss. Finally, an accurate throughput derivation formula for pipelined NCL circuits was developed, which can be used for static timing analysis.
