Professor of Electronic and Computer System Engineering

Profile

Professor Tanya Vladimirova’s research area is in custom computing for edge intelligence, which is intersection of embedded systems design, software, hardware, networking, digital signal processing, and artificial intelligence (AI).  

Her expertise includes development of reliable intelligent embedded systems for AIoT (Artificial Intelligence of Things) that meet application requirements and covers the whole development cycle from algorithm investigation and modification through modelling to software implementation and hardware acceleration on embedded computing platforms such as Field Programmable Gate Arrays (FPGAs), Multi-core processors, and Graphical processing units (GPUs). There are numerous application areas for this type of systems including robotic systems, smart phones, aircraft, autonomous cars, and spacecraft; the Internet of things (IoT) being the largest and fast growing application field of embedded intelligence. 

A key focus of Professor Vladimirova’s research has been the development of reliable and intelligent high-performance computing systems on board satellites, capable of withstanding the effects of some of the hazards of the space environment.  

The research started at the Surrey Space Centre of the University of Surrey in Guildford, where Professor Vladimirova worked closely with the leading UK small satellite manufacturer, Surrey Satellite Technology Limited (SSTL). The research group that she founded and led there became internationally recognised for pioneering new ideas and innovative solutions, such as the following: 

  • the first satellite on-board computer implemented as a reconfigurable system-on-a-chip design; 
  • the first design and prototype of a femto-satellite based on a single printed circuit board (PCBSat); 
  • the first satellite-on-a-chip feasibility study; 
  • the first low power radiation hardening by design method using asynchronous logic; 
  • the first model of a space-based wireless sensor network using a shared distributed computing platform;
  • the first fault-tolerant AES algorithm for encryption of satellite images on board;
  • the first implementation of the CCSDS algorithm for lossless compression of multispectral satellite images on a reconfigurable FPGA; and 
  • the first feasibility study on flood monitoring using small satellites. 

This work was continued at the School of Engineering of the University of Leicester, which Professor Vladimirova joined in 2011, where the following main achievements were accomplished:  

  • the first multi-sensor data fusion system in wireless sensor networks for interplanetary exploration;
  • the first implementation of KLT-based adaptive lossless / lossy compression of hyperspectral satellite imagery on FPGAs;
  • the first distributed Fault Detection Isolation and Recovery (FDIR) scheme for spaceborne reconfigurable multi FPGA-based systems ; 
  • the first design and prototype of a cooperative self-healing distributed intra-satellite computing system; 
  • the first distributed GNSS receiver for space-based wireless sensor networks; and 
  • the first design of an automated system for variable-rate fertilizer management using satellite imagery. 

Current projects are focused on Machine Learning techniques for improving reliability of sensor data processing in Satellite Payloads and efficient image processing in Self-Driving Cars. 

Research

My research interests are in the areas of embedded computing and microelectronics design for autonomous intelligent cyber physical systems & IoT. Current activities can be divided into four streams:

  • High-performance data and image processing in intelligent networked embedded systems.
  • Hardware acceleration of computationally intensive DSP & AI algorithms using FPGAs and ASICs.
  • VLSI system-on-a-chip design for hostile environments with a focus on reliability and low power.
  • Fault-tolerant cooperative distributed systems.

Targeted application domains are: space, aerospace, automotive, medical analysis.
