A system for the synthesis of singing on the basis of an articulatory speech synthesizer is presented. To enable the synthesis of singing, the speech synthesizer was extended in many respects. Most importantly, a rule-based transformation of a musical score into a gestural score for articulatory gestures was developed. Furthermore, a pitch-dependent articulation of vowels was implemented. The r...

In this paper, we extend the set of library components which are usually considered in architectural synthesis by components with built-in chaining. For such components, the result of some internally computed arithmetic function is made available as an argument to some other function through a local connection. These components can be used to implement chaining in a datapath in a single compone...

Pass-Transistor Mapper (PTM), a logic synthesis tool speci cally designed for passtransistor based logic library that has only three basic cells, is reported. It exploits the close relationship between BDD representation of logic and the structure of pass-transistor logic cells to ensure e cient technology mapping. BDD variable order optimization is achieved through a genetic algorithm with dyn...

| Domino logic is a circuit family that is wellsuited to implementing high-speed circuits. Synthesis of domino circuits is more complex than static logic synthesis due to the non-inverting nature of the logic and the complex timing relationships associated with the clock scheme. In this paper, we address several problems along a domino synthesis ow. We mainly consider the problem of partitionin...

In this paper, an analysis is presented, which demonstrates the effect pre-logic factoring could have on an automated combinational logic synthesis process succeeding it. The impact of pre-logic factoring for some arbitrary combinatorial circuits synthesized within a FPGA based logic design environment has been analyzed previously. This paper explores a similar effect, but with the non-regenera...

Objective of this paper is to present historiography of logic switching circuits. The research mainly focuses on chronological development and application of logic in the field of electronic and computer applications. This paper briefly discussed on the basic needs of logic synthesis and also discuss few interesting facts and design consideration regarding logic synthesis. It also enhances stud...

In this paper, we present a partitioning approach of parallel logic synthesis, which is diierent from the previous approaches which involved parallelization of individual operations within the synthesis algorithm. We partition the given logic circuits and distribute the partitions to diierent processors for synthesis. For good load balancing, partitioning algorithm is tuned so that the estimate...

As feature sizes shrink to deep sub-micron, the performance of VLSI chips becomes dominated by the interconnect delay. In a traditional top-down design ow, logic synthesis algorithms optimize gate area or delay without accurate interconnect delay because of lack of physical design information. Thus, the e ectiveness of the optimization techniques is limited. We integrate logic synthesis and phy...
