Implementation of Multiple-Output Functions Using PQMDDs
نویسندگان
چکیده
A sequential realization of multiple-output logic functions is presented. A conventional sequential realization is based on SBDDs (Shared reduced ordered Binary Decision Diagrams). In this paper, we propose PQMDD (Paged Quasi-reduced ordered Multi-valued Decision Diagram) as a new data structure. A function is represented by a PQMDD, and stored in memory. Dedicated control circuits traverse the PQMDD in parallel. We represent multiple-output function for benchmark functions by SBDDs and PQMDDs and compare the size of memory and computation time.

متن کاملExact Closed-Form Solution for Vibration Analysis of Truncated Conical and Tapered Beams Carrying Multiple Concentrated Masses
In this paper, an exact closed-form solution is presented for free vibration analysis of Euler-Bernoulli conical and tapered beams carrying any desired number of attached masses. The concentrated masses are modeled by Dirac’s delta functions which creates no need for implementation of compatibility conditions. The proposed technique explicitly provides frequency equation and corresponding mode ...
متن کاملConical Conformal Antenna Design using the CPM Method for MIMO Systems
Abstract- In this article, the design of conformal antennas has been discussed using the characteristic modes (CM) method. For this purpose, the vector wave function(VWF) has been utilized to achieve a two-dimensional mapping of the conformal antenna. In designing and analyzing of cone-shaped antennas applicable for multi-input multi-output (MIMO) systems, the most important goal is to achieve ...

متن کاملIdentification of Multiple Input-multiple Output Non-linear System Cement Rotary Kiln using Stochastic Gradient-based Rough-neural Network
Because of the existing interactions among the variables of a multiple input-multiple output (MIMO) nonlinear system, its identification is a difficult task, particularly in the presence of uncertainties. Cement rotary kiln (CRK) is a MIMO nonlinear system in the cement factory with a complicated mechanism and uncertain disturbances. The identification of CRK is very important for different pur...
