Education:^{(click on items to show/hide details!)}

• EngD. (Engineering Doctorate) in Large Scale Complex IT systems - University of York, UK (2010-2011)
  • Department: Department of Computer Science (Real-time systems research group)
  • Thesis: Dynamic Resource Management of Network-on-Chip Platforms for Multi-stream Video Processing
  • Description: This thesis considers resource management in the context of parallel, multiple, real-time video stream decoding, on many-core platforms. The targetted applications have dynamic and unpredictable characteristics. This, combined with the issue of resource contention in highly parallel systems make the problem of resource management very challenging. In this context, this thesis presents admission control techniques, blocking and application-aware runtime task allocation heuristics and a low-overhead fully distributed remapping technique in order to balance the predictability, resource utilisation and performance of the system.
• MSc. in Digital Systems Engineering - University of York, UK (2010-2011)
  • Department: Department of Electronics
  • Final project: Design and Implementation of a FPGA-based music player
  • Description: In this group project, a Field Programmable Gate Array (FPGA) based audio player had to be designed, implemented and tested from the ground-up including the PCB design. The resultant embedded system is a balance between custom reconfigurable hardware and Embedded C software running on a Xilinx Spartan 6 (with 32-bit MicroBlaze RISC soft-core processor). The final product has ability to play MP3/ADPCM encoded 16-bit stereo audio files at 24KHz (using a ported libmad MP3 library) from a microSD card. User input to the device was via buttons/rotary encoder and output was shown through the LCD screen and UART for debugging. (video)
  • Award: Distinction (78%, highest in cohort)
• BSc. in Network and Communication Engineering - University of Westminster, UK (2005-2008)
  • Department: Department of Electronics
  • Thesis: Simulation and analysis of the GMSK and 8PSK model implementations
  • Description: This thesis investigates the key properties of the GMSK and 8PSK digital modulation techniques, used in the GSM and EDGE mobile communication standards. The two modulation schemes are analysed in terms of their bit error rate performance, power spectra, inter-symbol interference distortion in gaussian noise and multi-path fading channels
  • Award: 1^st class honors (80%, highest in cohort)
