Download or read book Some State-assignment Techniques for Large Sequential Circuits written by Stanford University. Stanford Electronics Laboratories and published by . This book was released on 1964 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two state-assignment algorithms are developed, one of which has been programmed for a computer and will handle sequential machines as large as 128 states and 64 inputs. A flow table is used as the machine representation, and properties of the flow table are used to establish state-pair adjacency relationships. For these adjacency relationships a weighting procedure is presented which is used in determining the state codes. The set of state codes used in the algorithms is selected from those sets having some special properties which not only allow preselection of the codes but also reduce the enumeration required in the algorithms. In general, low-cost assignments were obtained without expending large amounts of time. (Author)

Book Synopsis Programmed State Assignment Algorithms for Asynchronous Sequential Machines by : Wayne L. Schoeffel
Download or read book Programmed State Assignment Algorithms for Asynchronous Sequential Machines written by Wayne L. Schoeffel and published by . This book was released on 1967 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: "An important step in the synthesis procedure for realizing a normal fundamental mode asynchronous sequential circuit is the internal state assignment. Although systematic methods have been developed to construct minimum-transition-time state assignments, they become long and tedious with hand methods for machines with more than 7 or 8 internal states. To extend the application of these algorithms to larger problems, this paper presents an efficient digital computer program for generating minimum-variable state assignments. An alternate program is also presented which, though shorter, does not guarantee a minimum-variable assignment"--Abstract, leaf ii.

Book Synopsis A Simplified State Assignment Method for Asynchronous Sequential Machines by : James William Ananias
Download or read book A Simplified State Assignment Method for Asynchronous Sequential Machines written by James William Ananias and published by . This book was released on 1961 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sequential switching circuits are generally categorized as being either synchronous or asynchronous circuits. Synchronous circuits are those which employ a timing or 'clock' signal to trigger circuit state changes. Asynchronous circuit state changes occur in response to input changes only. Output changes of these circuits are delayed from input changes by simply the switching time of the circuit elements and hence these circuits are capable of the ultimate in sequential circuit speed. Since asynchronous circuits are activated by input changes, unequal circuit path delays could result in undesired internal state transitions which in turn would result in faculty circuit operation. It is, therefore, necessary for asynchronous circuits to be free of such undesired internal state transitions for reliable operation. (Author).

Download or read book THE DESIGN OF MULTIPLE-VALUED ASYNCHRONOUS SEQUENTIAL CIRCUITS written by and published by . This book was released on 1974 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis examines several areas which are vital to the development of multiple-valued asynchronous sequential circuits. An existing method of designing multi-valued combinational circuits is analyzed in detail, and modifications are presented which extend the applicability of this design to more functions. Storage devices are also examined, and a device is presented which is simple to construct and is useful in the construction of asynchronous circuits. The problem of state assignment for multiple-valued circuits is studied in depth. Methods which minimize the number of state variables are presented, and then analogy to binary row-set and shared-row assignments is demonstrated. An algorithm for producing unicode single transition time assignments is developed, and is shown to produce optimal solutions. Various refinements on this method and other simpler but non-optimal methods is described.

Book Synopsis Optimal State Assignment of Sequential Circuits Using a Genetic Local Search with Flexible Cost Functions by : Eric Peter Olson
Download or read book Optimal State Assignment of Sequential Circuits Using a Genetic Local Search with Flexible Cost Functions written by Eric Peter Olson and published by . This book was released on 1996 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, we solve the finite state machine (FSM) state assignment problem using an implementation of a genetic local search algorithm (GLS) that selectively targets design goals with the use of flexible cost functions. Our GLS quickly converges toward a globally optimal state encoding, producing high quality solutions. We explore the properties of encoding-based (calculated from the encoding values) and synthesis-based (calculated from synthesis results) cost functions. With these functions, the GLS consistently finds the best known encoding solutions with FSMs of less than sixty states and very good assignments for larger benchmarks. The encoding-based functions reduce the number of literals and/or reduce the transition density of the state bits. The designs produced from these encodings were 11% smaller and consumed 10% less power than the designs from state-of-the-art state assignment tools. The inaccuracy inherent in any encoding-based cost function limits its application. We have overcome such inaccuracy by using cost functions based on actual synthesis. Area, power, and delay estimates are obtained by optimizing and mapping the encoding. The GLS allows synthesis-based cost functions to steer its selection so that the desired qualities of a solution can be preserved. We found empirically that our recombination procedure allowed the GLS to converge upon solutions with desired area, power, or delay characteristics with synthesis-based cost functions. Results for the MCNC benchmarks showed that these encodings produced circuits that were 21% smaller in area and 30% lower in power than those from state-of-the-art encoding tools. Furthermore, the synthesis-based cost functions produce encodings that lead to circuits with 20% less delays than for the state-of-the-art encoding tools. This dissertation provides an understanding of the relationship between state assignment and synthesis in terms of area, power, and delay. We describe a probabilistic power estimation tool for sequential circuits. We derive an accurate power estimate based on a zero-delay gate model of the design. This tool preserves all spatial and temporal correlations specified in the FSM description and eliminates the effects of reconvergent fanout. This tool is shown to be sufficiently fast enough to be used for cost calculation and accurate for design quality evaluation.

This book was released on 1967 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: "One step in the synthesis procedure for realizing an asynchronous sequential circuit that is operating in fundamental mode is to obtain an internal-state assignment that will realize the operations of the circuit. Often the procedures that are used in accomplishing the above task generate several satisfactory assignments. The first part of this paper presents a method that will enable one to predict which of the internal-state assignments will yield a simpler set of next-state expressions. A second topic treated in this paper is one of presenting a method to generate the next-state expressions for an asynchronous sequential circuit directly from the internal-state assignment. An algorithm is presented for generating the next-state expressions without construction of the transition table"--Abstract, leaf ii.
