VHDL Implementation of 4096-bit RNS Montgomery Modular Exponentiation for RSA Encryption

Modular exponentiation is the basis needed to perform RSA encryption and decryption. Execution of 4096-bit modular exponentiation using an embedded system requires many arithmetic operations. This work aims to improve the performance of modular exponentiation for an existing FPGA platform containing a soft core RISC-V processor. The solution is...

Optimising Motor Control in Actuator Alignment

The automation of replanting seedlings into bigger trays (transplanting) has been a major industrialisation step in the horticultural sector. Modern machines are abundant in large companies and are quite effective, but they are very expensive both in purchase and maintenance. With major clients taking these costs for granted, designers have not...

Polyhedral Compilation for Data Flow Computers

The increasing transistor density of Integrated Circuits (ICs) ever since their introduction, has scaled the computational performance of microprocessors. As a consequence of the gain in transistor density, the power dissipation density has also increased to a degree that has become a limiting factor in further performance scaling. The prevalent...

Computational Imaging for Earth Surveillance

Cameras are used in various applications and one such common application has been space. Delfi Space is the CubeSat Development program of the Delft University of Technology and a subprogram of Defi-Space is Delfi-PQ which aims to develop PocketQubes which are an order of magnitude smaller than the CubeSat standards. One of the advanced payloads...

Hierarchical Mapping: A Rao-Blackwellized Particle Filter based hierarchical SLAM framework

Mobile robots need to be fully autonomous in order to perform their tasks inside their environment. To do that, robots need to have an understanding of their environment, so that they can successfully localize and navigate themselves within it. The understanding of the robots' environment is created by solving the SLAM (Simultaneous Localization...

A light-weight Electromagnetic Based Embedded Sensing System For Ground Water Exploration

The availability of usable groundwater is fast becoming one of the most important environmental issues today. Though the availability of groundwater differs from place to place and more often the demand tends to overcome the supply. In spite of the numerous dowsing techniques that exists in the market today; till date there has been little work...
