The design of synchronous and asynchronous counter using sayem gate is proposed and the comparison is made in terms of number of gates, garbage output and power dissipation. Bahram Dehghan =-=[26]-=- presented asynchronous sequential circuits without hazard effect using reversible logic gates. ...
The proposed design applies both asynchronous and synchronous circuits to make the globally asynchronous data transfer rate between network nodes independent of local clocks.关键词: asynchronous circuits hardware description languages industrial property integrated circuit design integrated circuit interconnections ...
5.1.1Asynchronous and synchronous circuits In this introductory text we will define two broad classes ofsequential circuits, namely: asynchronous and synchronous. • The timing of the operation ofasynchronous circuits, as the name implies, is not controlled by any external timing mechanism. Rather,...
The synchronous procedure and the asynchronous procedure for the synthesis of a master-slave circuit are examined. It is shown that the synchronous procedure leads to a circuit operating in fundamental mode, while the asynchronous procedure can be performed by taking into account the synchronous flow...

Synchronous circuits exhibit a strict dissociation of signals into ○ One clock signal (or possibly more if of fixed frequency and phase relationship), ○ One asynchronous reset signal (optional), ○ An arbitrary number of information signals. • HDL synthesis does not dispense designers from deci...
A synchronous circuit system comprises a switch circuit for receiving an asynchronous imput signal only within a specified period in response to a synchronizing signal, a latch circuit connected to the switch circuit, a signal transmission circuit connected to the output of the latch circuit and adap...
