4 SWS project#
LED-based spectrometry for microplates#
Circuit design FPGA
Microplate is a standard tool for working with liquids in a laboratory. For autonomous measurements involving a measure-control loop it may be desirable to measure the changes in the liquids. For a low-cost measurement, LED-based spectrometry may be used. Example works are: 1, 2.
For the measurements, an RGB LED will shed a light on a single well and the reflected waves will be measured by a digital color sensor (e.g., VEML3328). Microplates can have thousands of wells, and the solution should show the feasibility for at least 96-well plates. To allow parallel measurement, an FPGA will be used instead of a microcontroller.
Autonomous charging for TurtleBot 3#
ROS 3d design Circuit design
An autonomous charging system for TurtleBot 3 Waffle Pi will be designed. Currently the robot’s battery must be detached for charging.
Most of the projects are designed to be done as a masters thesis but the workload and work can still be adjusted to fit the requirements of a bachelors thesis or simple project work.
Parity-based error detection for digital circuits using Yosys#
FPGA reliability open source
Local triple modular redundancy (LTMR) is often the first choice to harden the flip-flops of an application against radiation-induced bitflips in space, but LTMR leads to an area overhead of roughly 300%. To cope with this significant overhead, an error detection based approach can be used 1. To compare parity-based error detection with LTMR a tool for automatic application of these two approaches is needed.
Yosys is an open source synthesizer for digital logic. There is already a tool for applying LTMR based on Yosys 2.

Characterization of an HBM2-based FPGA accelerator#
FPGA parallel computing high bandwidth memory
Like GPUs, FPGA-based accelerators are used to improve processed data per Watt in data centers. Typically memory infrastructure on an FPGA is limited. To overcome this limit, high bandwidth memory (HBM) based FPGA accelerators emerged to increase the data throughput to the FPGA.

Comparison of Burrows Wheeler transformation on various computer architectures#
FPGA algorithms heterogeneous computing
Sequencing is the process of decoding gene information for medical diagnostics and biomedical research. Recent massive parallel sequencing3 techniques dramatically decreased the time and the costs involved in sequencing in last years, and paved the way for unprecedented medical diagnostics and prevention, e.g., for cancer patients.
Efficient computing of the work steps in the sequencing pipeline is beneficial to get results in a short time and in an energy-efficient way.
In this project we want to compare BWT on different computing architectures. Some examples are:
Two Multi-core processors connected on a mainboard
With GPU acceleration (e.g., Nvidia Tesla M60)
with FPGA acceleration on Alveo U280
