Artificial intelligence has made people’s demands for computer computing efficiency increasingly high. The traditional hardware circuit simulation method neural morphology computation problems of unstable performance and excessive power consumption. This research will use non-volatile flash memory cells that are easy to read write build a convolutional network structure improve the morphologica...

Broadband light sources play essential roles in diverse fields, such as high-capacity optical communications, optical coherence tomography, optical spectroscopy, and spectrograph calibration. Although a nonclassical state from spontaneous parametric down-conversion may serve as a quantum counterpart, its detection and characterization have been a challenging task. Here we demonstrate the direct...

With the continually increasing need for transmission of digital data over noisy channels, need for error control and correction techniques are also raising as well. There are various techniques and methods available for transmission of digital data over noisy channel but Viterbi Decoder is most efficient .It provides better coding gain at lower cost and good performance Convolutional encoding ...

Over the past decade, DNA has demonstrated remarkable potential in fabrication of molecular logic and arithmetic systems. In this work, a simple DNA-based system mimicking a full-subtractor that handles three inputs including one minuend and two subtrahends for eight input/output conditions is successfully designed. The whole system is established by one gate molecule and three input sequences,...

Floating Point operations is widely used in many areas, especially in signal processing. The greater dynamic range and lack of need to scale the numbers makes development of algorithms much easier. However, implementing arithmetic operations for floating point numbers in hardware is very difficult. The IEEE floating point standard defines both single precision (32-bit) and double precision (64-...

The paper presents current adder and subtractor circuits based on cascode current mirror with improved linearity and wide linear range. The proposed circuits can be used for analog signal processing applications such as amplifiers, operational transconductance amplifiers (OTA), Gm-C filters, etc. In the proposed circuits, cascode current mirror topology is employed to improve current mirroring ...

In this paper, we propose a novel approach to perform efficient motion estimation specific to surveillance videos. A real-time background subtractor is used to detect the presence of any motion activity in the sequence. Two approaches for selective motion estimation, GOP-by-GOP and Frame-byFrame, are implemented. In the former, motion estimation is performed for the whole group of pictures (GOP...
