In this research, we propose a heterogeneous anomaly-based intrusion detection system (HA-IDS) which is built on both of Field-Programmable Gate Array (FPGA) and Graphics Processing Unit (GPU) platforms. An essential anomaly-based IDS comprises of the two main components: Feature Construction Module (FC) to extract and collect network header information, and Classification Module (CM) to categorize...
Eye tracking is the method of tracking the user's eye gaze or where he is looking relative to his head. Its applications and studies were mostly done on general purpose computers. This study focuses on implementing an eye tracking system on a Field Programmable Gate Array (FPGA) and specifically a text-typing application. Using state machines implemented in Verilog – a hardware description language...
This article proposes a new hardware implementation for a Reconfigurable Neural Network for systems in which the topology needs flexibility. The used architecture is a MultiLayer Perceptron, where the entry of a layer depends on the output of the previous layer. The approach allows flexibility in the number of network inputs, neurons, layers and in the activation function executed by neurons. Despite...
Beidou and GPS are an important part of the GNSS (Global Navigation Satellite System). Beidou is a global satellite navigation system that is independent development and operation in China. GPS is the most mature development system in the world currently. The research on the Beidou/GPS multi-mode receiver has an important practical significance at present. Compared with hardware receiver, software...
This paper describes a cloud-based digital design environment for ASIC and FPGA. We call it CloudV. CloudV is built using open-source as well as homegrown EDA software tools. The ultimate goal of CloudV is to reduce the design costs by relying on cloud infrastructure and on collaborative design. Currently, CloudV v 1.0 allows students to gain hands-on experience in digital ASIC design tasks covering...
Verification is indispensable for building reliable of hardware/software co-designs. However, the scope of formal methods in this domain is limited. This is attributed to the lack of unified property specification languages, the semantic gap between hardware and software components, and the lack of verifiers that support both C and Verilog/VHDL. To address these limitations, we present an approach...
In today's modern era a theoretical based approach is followed to determine the amount of chlorophyll present in leaves of plants. But in this paper a practical based approach is followed to generate an architecture of simple, low cost Chlorophyll estimator using Field Programmable Gate Array(FPGA). Color of leaf can give an indication for assessing plant health and nutrient. Performance analysis...
The paper proposes a new approach for FPGA reconfiguration based on usage of the open-source synthesis and place-and-route tools. The well-known partial reconfiguration technologies assume pre-compilation of all required FPGA configurations by the designer. In autonomous intelligent control systems it can become quite a strong limitation, due to control law couldn't be changed on-board without using...
The DSP (Digital Signal Processing) has many advantages over the analog processing. Therefore, with the recent advent of technology most of the signal processing tasks have been transferred from the analog to the digital domain. The ADCs (Analog to Digital Converter) provide a liaison between the real world analog signals and the digital processors. Therefore, ADCs become an elementary part of almost...

QPSK is one of the digital modulation techniques in communication system that has wide applications in the field of wireless, satellite communication, Bluetooth, OFDM etc. The Conventional QPSK modulators designs are generally based on IQ approach. In these modulators multipliers are used to separate the modulating signal into the in-phase and quadrature phase which increases the hardware complexity...
This paper proposes a Quadrature Phase Shift Keying (QPSK) using two different methods. QPSK is one of the forms of Phase Shift Keying (PSK) modulation scheme. Generally a conventional QPSK modulator with Direct Digital Synthesizer (DDS) and arithmetic multiplier separates base band signal into I and Q phase which consumes low throughput with complexity in hardware implementation. Hence to generate...

For the economic development and progress of any country, roads play an important role by providing transportation ease for goods as well as for passengers. The number of vehicles on road is increasing day by day which are controlled by the traditional Traffic Light Controller in the countries like India and other developing countries. In traditional Traffic Light Controller, fixed time is allotted...
The important phase of any product design is the process engineering. For the processing, materials are require to transport from one plant to another and must be transported from one division to a different in the processing unit. Materials are typically conveyed in a fluid phase as this is normally easier and inexpensive than solid state transportation. Liquids can be easily moved through pipes...
