Introduction to Special Issue: Asynchrony in System Design
Montek Singh, Steven M. Nowick
Article No.: 14
DOI: 10.1145/2043643.2043644

Asynchronous Solutions for Nanomagnetic Logic Circuits
Marco Vacca, Mariagrazia Graziano, Maurizio Zamboni
Article No.: 15
DOI: 10.1145/2043643.2043645

In the years to come new solutions will be required to overcome the limitations of scaled CMOS technology. One approach is to adopt Nano-Magnetic Logic Circuits, highly appealing for their extremely reduced power consumption. Despite the...

A Novel Power Delivery Method for Asynchronous Loads in Energy Harvesting Systems
Xuefu Zhang, Delong Shang, Fei Xia, Alex Yakovlev
Article No.: 16
DOI: 10.1145/2043643.2043646

For systems depending on power harvesting, a fundamental contradiction in the power delivery chain has existed between conventional synchronous computational loads requiring relatively stable Vdd and power harvesters unable to supply it. DC/DC...

SpiNNaker: Design and Implementation of a GALS Multicore System-on-Chip
Luis A. Plana, David Clark, Simon Davidson, Steve Furber, Jim Garside, Eustace Painkras, Jeffrey Pepper, Steve Temple, John Bainbridge
Article No.: 17
DOI: 10.1145/2043643.2043647

The design and implementation of globally asynchronous locally synchronous systems-on-chip is a challenging activity. The large size and complexity of the systems require the use of computer-aided design (CAD) tools but, unfortunately, most tools...

Microarchitectural Transformations Using Elasticity
Marc Galceran-Oms, Alexander Gotmanov, Jordi Cortadella, Mike Kishinevsky
Article No.: 18
DOI: 10.1145/2043643.2043648

Elasticity is a paradigm that tolerates the variations in computation and communication delays. By applying elastic transformations that allow varying the original timing, circuits can be optimized beyond the conventional rigid transformations...

Energy-Efficient Pipeline Templates for High-Performance Asynchronous Circuits
Basit Riaz Sheikh, Rajit Manohar
Article No.: 19
DOI: 10.1145/2043643.2043649

We present two novel energy-efficient pipeline templates for high throughput asynchronous circuits. The proposed templates, called N-P and N-Inverter pipelines, use a single-track handshake protocol. There are multiple stages of logic within each...

Relativistic Causality and Clockless Circuits
Philippe Matherat, Marc-Thierry Jaekel
Article No.: 20
DOI: 10.1145/2043643.2043650

Time plays a crucial role in the performance of computing systems. The accurate modelling of logical devices, and of their physical implementations, requires an appropriate representation of time and of all properties that depend on this notion....
