Available in PDF, EPUB and Kindle. Book excerpt: One of the most important and complicated prob lems in the synthesis of a sequential machine, described by a state diagram or table is the as signment of the states of the secondary variables to the states of the machine. The secondary assignment for a given machine varies in accord ance with the requirements of the design. It has already been shown that the partition with the substitutiperty is of great significance in the secondary assignment. However, only few machines possess these properties, and hence, a more general method is needed. This paper pre sents a method for obtaining for any given machine M an equivalent machine M' which has a partition with the substitution property and therefore can be decomposed into several sub machines connected in cascade or in parallel. It is also shown that for machine M' we can find an assignment with self dependent subsets. The method is shown to be general for any completely or incompletely specified sequential machine.

Book Synopsis Some Aspects of the State Assignment Problem for Sequential Circuits by : Donald R. Haring
Download or read book Some Aspects of the State Assignment Problem for Sequential Circuits written by Donald R. Haring and published by . This book was released on 1962 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the major steps in the synthesis of switching circuits containing memory is the binary coding of the internal states. The choice of code, called the state assignment, strongly affects the complexity of the circuit realization. Hence, the objective is to find, for a given sequential machine (SM) as typically specified by a flow table and an output table, that state assignment (SA) which minimizes the sequential circuit (SC) complexity. The point of view is taken that the greatest lack in promoting an understanding of the SA problem is a knowledge of the structure of the relationship between the properties of the SM and the properties of the logic required by its SC realization. Consequently, a large part of this report is devoted to developing and using some new techniques for studying the structure of this SM-SC relationship. (Author).
Book Synopsis Switching and Finite Automata Theory by : Zvi Kohavi
Download or read book Switching and Finite Automata Theory written by Zvi Kohavi and published by Cambridge University Press. This book was released on 2010 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understand the structure, behavior, and limitations of logic machines with this thoroughly updated third edition. Many new topics are included, such as CMOS gates, logic synthesis, logic design for emerging nanotechnologies, digital system testing, and asynchronous circuit design, to bring students up-to-speed with modern developments. The intuitive examples and minimal formalism of the previous edition are retained, giving students a text that is logical and easy to follow, yet rigorous. Kohavi and Jha begin with the basics, and then cover combinational logic design and testing, before moving on to more advanced topics in finite-state machine design and testing. Theory is made easier to understand with 200 illustrative examples, and students can test their understanding with over 350 end-of-chapter review questions.

Download or read book The State Assignment Problem for Sequential Machines written by George E. Brown and published by . This book was released on 1971 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some results are described on the synthesis of sequential machines with partitions. Also included are techniques for handling machines without partitions. It is shown that a minimal state machine realization can always be obtained in a completely systematic way, such that the state variable and output variable dependencies are reduced simultaneously. The scheme presented in this paper is the Implication Graph. (Author).

Book Synopsis Secondary State Assignment and Decomposition of Sequential Machines by : Avi Kohavi
Download or read book Secondary State Assignment and Decomposition of Sequential Machines written by Avi Kohavi and published by . This book was released on 1966 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the first part of the paper a method is developed to obtain for any given machine M which is in reduced form and undecomposable an equivalent machine M' which possesses a partition with substitution property or partition pairs. Therefore, a state assignment or assignments with reduced dependency exist for M'. The method requires augmentation of the original machine M by a technique of state-splitting. It should be noted that the augmentation does not necessarily increase the complexity of the logic required for the implementation and, in fact, often reduces it. The problem of finding cascade decompositions for two or more reduced machines which have the same input, such that a common submachine may be factored out and serve as a predecessor machine feeding two or more successor machines is examined. Necessary and sufficient conditions under which it is possible to obtain decompositions which contain such a common submachine are developed. If the given machines do not satisfy these conditions, and a common submachine cannot be found, it is shown how one or both machines can be replaced by equivalent machines in such a way that some common submachine can be found. A systematic method has been developed for the determination of the common factor. The basic tool, in this study is the composite machine (CM) which is derived from the original machines. The properties of the CM are studied and the maximal common factor is obtained with a minimum of computation or manipulation. (Author).

Book Synopsis Optimizing the Assignment Problem in the Synthesis of Sequential Machines by : Jesse W. HALSEY
Download or read book Optimizing the Assignment Problem in the Synthesis of Sequential Machines written by Jesse W. HALSEY and published by . This book was released on 1964 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: A procedure for assigning binary codes to the inputs of a sequential machine is examined in an attempt to mechanize the procedure using linear programming. Reasons are given for the difficulty involved in attempting to derive linear constraining equations for an objective function specified by the procedure. In the second part of this thesis, the partition-pair on the set of states of a sequential machine is extended to the inputs of a sequential machine in an effort to simplify the logical equations. It is shown that input-state pairs are effective in obtaining the simplification of these logical equations. (Author).
Book Synopsis Synthesis of Finite State Machines by : Tiziano Villa
Download or read book Synthesis of Finite State Machines written by Tiziano Villa and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synthesis of Finite State Machines: Logic Optimization is the second in a set of two monographs devoted to the synthesis of Finite State Machines (FSMs). The first volume, Synthesis of Finite State Machines: Functional Optimization, addresses functional optimization, whereas this one addresses logic optimization. The result of functional optimization is a symbolic description of an FSM which represents a sequential function chosen from a collection of permissible candidates. Logic optimization is the body of techniques for converting a symbolic description of an FSM into a hardware implementation. The mapping of a given symbolic representation into a two-valued logic implementation is called state encoding (or state assignment) and it impacts heavily area, speed, testability and power consumption of the realized circuit. The first part of the book introduces the relevant background, presents results previously scattered in the literature on the computational complexity of encoding problems, and surveys in depth old and new approaches to encoding in logic synthesis. The second part of the book presents two main results about symbolic minimization; a new procedure to find minimal two-level symbolic covers, under face, dominance and disjunctive constraints, and a unified frame to check encodability of encoding constraints and find codes of minimum length that satisfy them. The third part of the book introduces generalized prime implicants (GPIs), which are the counterpart, in symbolic minimization of two-level logic, to prime implicants in two-valued two-level minimization. GPIs enable the design of an exact procedure for two-level symbolic minimization, based on a covering step which is complicated by the need to guarantee encodability of the final cover. A new efficient algorithm to verify encodability of a selected cover is presented. If a cover is not encodable, it is shown how to augment it minimally until an encodable superset of GPIs is determined. To handle encodability the authors have extended the frame to satisfy encoding constraints presented in the second part. The covering problems generated in the minimization of GPIs tend to be very large. Recently large covering problems have been attacked successfully by representing the covering table with binary decision diagrams (BDD). In the fourth part of the book the authors introduce such techniques and extend them to the case of the implicit minimization of GPIs, where the encodability and augmentation steps are also performed implicitly. Synthesis of Finite State Machines: Logic Optimization will be of interest to researchers and professional engineers who work in the area of computer-aided design of integrated circuits.

Book Synopsis VLSI Design Environments by : George Zobrist
Download or read book VLSI Design Environments written by George Zobrist and published by CRC Press. This book was released on 2000-04-17 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: VLSI Design Environments investigates design alternatives such as object oriented data modelling. The difficulty of automating chip architecture designs is caused by the complexity of the problem. The explosion of design decions make a heuristic approach necessary. PLAYOUT aims at the solution of system problems based on hierarchy, top-down planning, silicon complier presentations, advances in encoding logic synthesis and a microarchitecre and logic optimization system. PLAYOUT supports the physical design from entering the structure of digital systems to the generation of the mask. The concept for autonomous tools with a clear interface to the network description and the simple interface to the graphics is presented. This enables the designer to have a great influence on the configuration of the placement of the schematic diagram. Substantial progress is being made in behavioural and logic synthesis, both of which depend upon specifications.
