Improvement of tagged architecture for preventing software vulnerabilities
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
In spite of the many defense techniques, software vulnerabilities like buffer overflow, format string vulnerability and integer vulnerability is still exploited by attackers. These software vulnerabilities arise due to ...
High-speed 512-point FFT single-chip processor architecture
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
This thesis present a fully parallel novel fixed point 16-bit word width 512 point FFT processor architecture. The 512 point FFT is realized by decomposing it into three 8 point FFT units. This approach reduces the number ...
Single frame superresolution
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Super-resolving an image from single frame observation image. In many cases more than one low resolution observations may not be available, need high spatial resolution images e.g. medical imaging, remote sensing etc.. We ...
Accurate on-chip current sensing technique for Buck converter
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Current mode bucks converters have many advantages over voltage mode control such automatic over-current protection, Better stability, better line regulation and faster dynamic response. Many different current sensing ...
Exploring small world effect in ad hoc network
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Small world is a highly clustered i.e., a densely and fully connected network, with low degree of separation between the nodes. These networks have inherited the high clustering property of regular networks and low average ...
Wireless sensor network based automatic meter reading: WSNAMR
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Automatic Meter Reading is technology evolved from 1995[3] or before, for remote collection of utilities measurement data which involve Electricity, Gas and Water etc. In this process of evolution every time new idea was ...
6bit 800 MHz time-interleaved analog to digital converter based on successive approximation in 65 nm standard CMOS process
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
High-speed analog-to-digital converters (ADCs) with resolutions of 6 bits find wide application in instrumentation, wireless systems, optical communication. This dissertation presents a 6 bit, 8 channel Time-Interleaved ...
Particle swarm optimization based synthesis of analog circuits using neural network performance macromodels
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
This thesis presents an efficient an fast synthesis procedure for an analog circuit. The proposed synthesis procedure used artificial neural network (ANN) models in combination with particle swarm optimizer. ANN has been ...
Transaction based verification of DA-FIR filter using AMBA AHBTm transactor
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Transaction based verification is used for faster verification purpose. Reusable transactors are designed and designs are verified at transaction level using these transactors. The test bench are written in higher level ...
