A growable ATM switch architecture is desired for constructing a large scale ATM switch. All the current ATM switch architectures are based on uniform connections of unit switch elements. When the switch size becomes large, the uniform switch architecture is no longer suitable for the nonuniform trafic condition. In this paper, we propose a nonuniform modular growth ATM switch architecture by u...

The efficient use of energy in communications is an area of growing interest. Until recently energy efficiency received little attention in most wireline communications standards and implementations. In almost all cases, the transmitter and receiver operate at full power, even when no data is being sent. This is the case in most wireline Ethernet standards and results in a considerable waste of...

In this paper we present a novel parallel arithmetic architecture using an efficient non-binary logic scheme. We show that by using parallel broadcasting (or domino propagating) state signals, on short reconfigurable buses equipped with a type of switches, called GP (generate-propagate) shift switches, several arithmetic operations can be carried out efficiently. We extend a recently proposed s...

We consider crossbar switching networks with base b (that is, constructed from b × b crossbar switches), scale k (that is, with b inputs, b outputs and b links between each consecutive pair of stages) and depth l (that is, with l stages). We assume that the crossbars are interconnected according to the spider-web pattern, whereby two diverging paths reconverge only after at least k stages. We a...
