The Bluetooth protocols have been developed to support wireless transmission within personal area networks; primarily serving as a cable replacement technology for mobile devices. The standard protocol provides support for synchronous transmission of audio and asynchronous transmission of data. In general, the standard was developed to use synchronous connection-oriented (SCO) channels to trans...

We present a local clocking mechanism based on a tunable delay line which calibrates itself from a low frequency global clock. After initial tuning, the local clock remains calibrated when environmental conditions change. Each module of a large system on a chip can use one of these clock generators running at the optimal frequency for the module. Communication between locally synchronous blocks...

Verifiable secret sharing (VSS) is a vital primitive in secure distributed computing. It allows an untrusted dealer to verifiably share a secret among n parties in the presence of an adversary controlling at most t of them. VSS in the synchronous communication model has received tremendous attention in the cryptographic research community. Nevertheless, recent interest in deploying secure distr...

Interconnect fabric requires easy integration of computational block operating with unrelated clocks. This paper presents asynchronous interconnect with ternary tree asynchronous network for Globally Asynchronous Locally Synchronous (GALS) system-on-chip (SOC). Here architecture is proposed for interconnection with ternary tree asynchronous network where ratio of number NOC design unit and numb...

Checkpointing algorithms are classiied as synchronous and asynchronous in the literature. In synchronous checkpointing, processes synchronize their checkpointing activities so that a globally consistent set of checkpoints is always maintained in the system. Synchronizing checkpointing activity involves message overhead and process execution may have to be suspended during the checkpointing coor...

In this paper, we propose a VLSI implementation method for one-dimensional discrete wavelet transform (1D-DWT) based on the GALS systems approach. An asynchronous wrapper, which includes two data communication ports and a local clock controller, is designed for the asynchronous data communication between the locally synchronous filtering modules in the wavelet filter bank. The detailed design m...

We study the problem of stochastic optimization for deep learning in the parallel computing environment under communication constraints. A new algorithm is proposed in this setting where the communication and coordination of work among concurrent processes (local workers), is based on an elastic force which links the parameter vectors they compute with a center variable stored by the parameter ...

Anonymous mobile robots are often classified into synchronous, semi-synchronous and asynchronous robots when discussing the pattern formation problem. For semi-synchronous robots, all patterns formable with memory are also formable without memory, with the single exception of forming a point (i.e., the gathering) by two robots. (All patterns formable with memory are formable without memory for ...

Asynchronous communications are prominent in distributed and mobile systems. Often concurrent systems consider an abstract point of view with synchronous communications. However it seems more realistic and finer to consider asynchronous communicating systems, since it provides a more primitive communication protocol and maximize the concurrency. Several languages and models have been defined us...
