Ternary content-addressable memory (TCAM) has become popular in high-speed lookup intensive applications. Large dynamic power consumption of TCAMs makes power reduction techniques an active area of research. In this paper we present a new match-line (ML) sensing scheme employing ML segmentation and positive feedback in the sense amplifier of the first segment. Simulation using 130nm 1.2V CMOS logic...
Quaternary logic requires a dedicated comparator circuit besides the usual add/sub unit which may not be optimal due to several reasons. In this paper, we have thoroughly discussed various alternative expressions for equality operator which serves as the basis for quaternary comparator. Then we have derived the necessary equations for single qudit comparator and extended it to serial multi qudit comparator...
A neural representation of combinational logic circuit is proposed, called `Logical Neural Network' (LNN). LNN is a feed-forward neural network (NN) where the weights of the network indicate the connections of digital circuit. The logic operations of the circuit such as AND, OR, NOR etc are performed with the neurons of LNN. A modification of Simple Genetic Algorithm (mSGA) is applied to design and...
