How to build fast muscles: synchronous and asynchronous designs.

In animals, muscles are the most common effectors that translate neuronal activity into behavior. Nowhere is behavior more restricted by the limits of muscle performance than at the upper range of high-frequency movements. Here, we see new and multiple designs to cope with the demands for speed. Extremely rapid oscillations in force are required to power cyclic activities such as flight in inse...

Synchronous and Asynchronous Muscles in Cicadas*

1. The tymbal muscles of the cicada Cyclochila australasiae Donovan are synchronous, those of Platypleura capitata (Oliv.) asynchronous. The tymbal structure and the individual sound pulses are similar in the two species. The sound pulse frequency during calling song is higher in P. capitata (389 Hz) than in C. australasiae (234 Hz). 2. Muscle action potentials during protest songs are simultan...

A Digital Clock Multiplier for Globally Asynchronous Locally Synchronous Designs

For large high-speed globally synchronous ASICs, designing the clock distribution net becomes a troublesome task. Besides problems caused by clock skew, the clock net also is a major source of power consumption. Partitioning the design into locally clocked blocks reduces clock skew problems and if handled correctly it also reduces power consumption. However, to achieve these positive effects, t...

High Resolution Clock Generators for Globally-Asynchronous Locally-Synchronous Designs

As explained in the companion paper by Thomas Villiger et. al. and in [1] a GALS system is partitioned into many Locally-Synchronous Islands, such as the one shown in Fig. 1. The GALS approach restricts the asynchronous parts to some well-known circuits contained in a Self-Timed Wrapper around each Synchronous Island and makes it possible to use the synchronous design paradigm for the Synchrono...

Testing of Asynchronous Designs by "Inappropriate" Means: Synchronous Approach

The roadblock to wide acceptance of asynchronous methodology is poor CAD support. Current asynchronous design tools require a significant re-education of designers, and their capabilities are far behind synchronous commercial tools. This paper considers the testing methodology for a particular subclass of asynchronous circuits (Null Convention Logic or NCL) that entirely relies on conventional ...
