About Me
I am mostly interested in low level and kernel development but I do not exclude other Computer Science fields as they all seem to be interesting. As a supporter of open source, I prefer to use OSS tools.
Languages: Greek, English
Programming: C/C++, python, MIPS assembly, linux shell, SQL
Preferred tools: git, vim, eclipse, sublime
Experienced with: Arduino Uno, Zynq7000 SoC
Research
This work was a research of my university's embedded computing systems lab
In this publication an external and an internal FPGA configuration memory scrubbing systems are presented. Both system are implementing the proposed 2D mixed coding technique described in the paper. I helped on the development of the external scrubber as part of my thesis.
Single Event Effects Characterization of the Programmable Logic of Xilinx Zynq-7000 FPGA using Very/Ultra-High Energy Heavy Ions
2020
This work was a research of my university's embedded computing systems lab
Following the “Analysis of the Single Event Upsets in the Programmable Logic of 28 nm Xilinx Zynq-7000 FPGA due to Heavy Ion Irradiation” study, this paper makes a more in depth analysis of single event effects.
Analysis of the Single Event Upsets in the Programmable Logic of 28 nm Xilinx Zynq-7000 FPGA due to Heavy Ion Irradiation
2019
This work was a research of my university's embedded computing systems lab
Shortly, my university’s embedded computing systems lab placed an FPGA device (Xilinx Zynq-7000 SoC) in front of a beam in the CERN’s SPS-NA facility and they exposed the chip to heavy ion radiation. At the same time, they were recording periodically the state of the chip to collect data of SEE (Single Event Effects) due to the radiation.
The data analysis had many aspects. I wrote some scripts to visualize the errors and to create images of the patters.
Projects
FPGA Fault Injection Platform via JTAG (FFIP)
https://gitlab.com/AntGeorge/extscrubberHigh performance FPGA fault injection platform using an external board connected via JTAG. The system is running on the PS (ARM cortex-a9) side of the Zynq7000 family chip. A custom axi2jtag IP core has been implemented to achieve high performance read/write memory transactions. Using back-to-back technique for frame read and write we achieved ~200 microseconds for frame configuration read/write with the JTAG clock set on 41Mhz.
Key feutures:
- Configuration memory fault injection
- (to be tested) BRAM fault injection
- Flip Flop fault injection
- Autocalibration of JTAG clock based on connection conditions (e.g. cable length)
- Custom IO pins interface for design specific signal
- (in development) Execute fault injection session using a file in SD card

2021 - Present
The Departments of Informatics and Telecommunications and Physics, the School of Sciences, the National and Kapodistrian University of Athens and the Electrical Engineering and Technology of Computers and Mechanical and Aeronautical Engineering of the Polytechnic School of the University of Patras will organize and operate from the academic year 2019-2020 the Postgraduate Postgraduate Program entitled "SPACE TECHNOLOGIES, APPLICATIONS AND SERVICES" (Space Technologies, Applications and SeRvices - STAR).
The University of Piraeus was founded as a "School of Industrial Studies" in 1938 by the Association of Industrialists and Craftsmen, in accordance with the Law N.5197/1931 and the A.N. 28/1936, in association with the Federation of Public Limited Companies Greece intending to provide economic, legal and technical education to industrial executives.
GPA: 8.64/10
The topic of my thesis was about the implementation of an FDIR (Fault Detection, Isolation and Repair) scrubbing algorithm on the ARM processor of a Zynq7000 chip. In addition for the proper testing of the scrubber the FFIP (FPGA Fault Injection Platform) has been developed.
