An improvement of the majority gate algorithm suitable for grey scale morphological operations is presented in this letter. The redundancy of temporal signals led to a simplified hardware implementation. It is shown that max/min operators can be computed by the same circuit. A new pipelined systolic array architecture based on this circuit is illustrated for dilation/erosion operations. 2 Intro...

A spin wave majority fork-like structure with feature size of 40 nm, is presented and investigated, through micromagnetic simulations. The structure consists of three merging out-of-plane magnetization spin wave buses and four magneto-electric cells serving as three inputs and an output. The information of the logic signals is encoded in the phase of the transmitted spin waves and subsequently ...

Majority-logic decoding is attractive for three reasons: (I) It can be simply implemented; (2 ) the decoding delay is short; and (3) its performance, while suboptimal, is always superior to bounded distance decoding. For these reasons, majoritylogic decodable cyclic codes are very suitable f o r error control in high speed digital data transmission systems. Among the majority-logic decodable co...

Quantum cellular automata (QCA) is expected to provide highly dense nanotechnology implementations of logic. However, unlike the CMOS technology, the designs in QCA are constrained by the limited number of basic gate structures. This paper describes an important new basic building block, a five input majority gate (MAJ5) in QCA technology. Many new functions can be directly implemented in a sin...

This paper presents the design and VLSI implementation of a new ASIC which performs in real-time the morphological operations of dilation and erosion. The ASIC's architecture is based on the extension of the majority-gate algorithm for morphological operations. The ASIC was implemented using a DLM, 0.7 ìm, CMOS, N-well process and it occupies a silicon area of 14.78mm2. Its maximum speed of ope...

A new technique for implementation of morphological edge detectors, including median prefiltering is presented in this paper. The proposed technique uses a bit-serial algorithm based on the majority gate. Several morphological edge detectors are studied and experimental results are also presented.

A Quantum Cellular Automaton (QCA) is a nanotechnology which is an attractive alternative for transistor based technologies in the near future. A new seven input majority gate in quantum dot cellular automata is proposed in this paper. The basic elements in QCA are majority and inverter gates, therefore using a majority gate with more inputs in QCA circuit will cause reduction in cell count, la...

We describe the operation of, and demonstrate logic functionality in, networks of physically coupled, nanometer-scale magnets designed for digital computation in magnetic quantum-dot cellular automata (MQCA) systems. MQCA offer low power dissipation and high integration density of functional elements and operate at room temperature. The basic MQCA logic gate, that is, the three-input majority l...

-A new technique for the implementation of a single hardware structure capable of computing any rank order filter is presented in this paper. The proposed technique, which is based on the majority gate, achieves faster extraction of setting flag signals and, therefore, shorter processing times are attained. A pipelined systolic array, suitable for performing rank order filtering, is also presen...

In this paper, a novel efficient method for optimizing multi-output majority gate based designs is proposed. Majority gate is a fundamental Boolean operator in some nano-scale technologies such as quantum-dot cellular automata (QCA). As a result, the design optimization must be directly implemented on majority gates instead of optimizing the design for AND–OR gates. In some other nanotechnologi...
