Abstract:This paper presents a new approach to implement Reed-Muller Universal Logic Module (RM-ULM) networks with reduced delay and hardware for synthesizing logic functions given in Reed-Muller (RM) form. Replication of single control line RM-ULM is used as the only design unit for defining any logic function. An algorithm is proposed that does exhaustive branching to reduce the number of levels and modules required to implement any logic function in RM form. This approach attains a reduction in delay, and power over… Show more

“…Ease of complementing and testing is an added advantage of this representation. Lot of work has been done in this area regarding design and minimization techniques for RM logic, and conversion between RM and Boolean functions [6], [7].Implementation of RM functions can be made using discrete components or Reed Muller Universal Logic Modules (RM ULMs). Here single control line RM-ULM has been used for implementing a logic function given in positive polarity Reed-Muller (PPRM) form.…”

“…A logic function with n-variables can be realized using 2 n -1 RM-ULM (1) s with n levels by standard implementation. Any implementation using less than 2 n -1 number of modules and / or lesser number of levels can be considered as an improvement in cost and or speed [6]. (1) is a device with 1-control input, 2 data inputs and a single output F. Its behavior is described as…”

“…In [5] A.H.Aguirre made an attempt to design combinational digital circuits using 2-1 multiplexers with Genetic programming. In [8], authors proposed the design of combinational logic circuits with 2 to 1 multiplexers using GA. Two different algorithms have been proposed in [6] using RM ULM, but it was not based on evolutionary techniques. They also have tested Boolean functions only up to 4 variables.…”
Conventional design of digital circuits is a very complex task which requires much knowledge in domain-specific rules. But, combinational digital circuits can be evolved automatically using evolutionary techniques. This work proposes new approaches for the automated design of combinational digital circuits using Genetic Algorithm (GA) and Reed Muller Universal Logic module (RM ULM). Here 2-1 RM-ULM has been used as the only design unit for the automated design of combinational digital circuits. Certain modifications have been made on the existing Shannon's decomposition technique for the design. Several circuits are synthesized with these modified methods and compared with the existing standard implementation technique using single control line Reed Muller Universal Logic Modules(RM ULM(1)). Manufacturing cost can be reduced by replicating the same element. With this method, the number of levels required as well as the number of modules needed is reduced considerably, thus reducing the cost, delay and power consumption.
