Semi- and fully-random access LUTs for smooth functions
Gener, Y. S.; Aydın, F.; Gören, S.; Uğurdağ, Hasan Fatih (Springer, 2020)Look-Up Table (LUT) implementation of complicated functions often offers lower latency compared to algebraic implementations at the expense of significant area penalty. If the function is smooth, MultiPartite table method ... -
Small form factor PCB-based air coil for CubeSats
pace missions using Earth's magnetic field to achieve effective attitude determination and control (orientation) is becoming more and more popular at relatively low altitudes, Low Earth Orbit (LEO). CubeSats (U-class ... -
SOC estimation for li-Ion batteries using extended kalman filter with PID controlled process noise according to the voltage error
Çelik, Mert; Gözüküçük, Mehmet Ali; Akdoğan, Taylan; Uğurdağ, Hasan Fatih (IEEE, 2019)State of Charge (SOC) estimation is critical for battery powered devices in order to find out the remaining charge level. This process is relatively straightforward when the battery is in the resting state. However, it can ... -
Software defined VLC system: implementation and performance evaluation
Hussain, Waqas; Uğurdağ, Hasan Fatih; Uysal, Murat (IEEE, 2015)This paper presents the implementation of an IEEE standard-based Visible Light Communication (VLC) system using software defined radio (SDR) approach. Based on widely used SDR platform Universal Software Radio Peripheral ... -
Software UART: A use case for VSCPU worst-case execution time analyzer
Yıldız, A.; İskender, Deniz; Özlü, G.; Uğurdağ, Hasan Fatih; Aktemur, Tankut Barış; Gören, S. (IEEE, 2019)This paper presents our early results of the development of a Worst-Case Execution Time (WCET) analyzer for VSCPU by implementing a software UART system. Our WCET analyzer takes a C program as input and gives the time taken ... -
Standard-compliant and software defined VLC system: implementation and performance evaluation
Hussain, Waqas (2015-08)LED lighting is now a cost-effective and energy-efficient technology for general-purpose illumination. Recent advances in LED lighting allow us to use LEDs not only for illumination but at the same time for wireless ... -
State of charge estimation for lithium-based batteries
Çelik, Mert (2020-01)This thesis proposes a new State of Charge (SOC) estimation method for lithiumbased batteries, which o ers a good trade-o between convergence and computation times. Lithium-based battery packages are quite common in the ... -
A sub-sampling pulse-resonance OOK modulated digital ultrasound communication system for medical IOT
Abouzeid, Mohamed Osama Hussein Soliman (2018-04)This dissertation presents a new ultrasound communication microsystem (Pulsed Resonance On-Off Keying) as a viable alternative to today's widely used RF technologies in order to avoid the associated health risks. Special ... -
Synthesis of clock trees for sampled-data analog IC blocks
Yüce, B.; Korkmaz, S.; Esen, V. B.; Temizkan, Fatih; Tunç, Cihan; Güner, Gökhan; Başkaya, I. F.; Agi, İ.; Dündar, G.; Uğurdağ, Hasan Fatih (IEEE, 2013)This paper describes a methodology for automated design of clock trees in Sampled-Data Analog Circuits (SDACs). The current practice in the industry and academia for clock tree design of SDACs is a manual process, which ... -
Tools and techniques for implementation of real-time video processing algorithms
Levent, Vecdi Emre; Güzel, Aydın Emre; Tosun, M.; Büyükmıhcı, Mert; Aydın, Furkan; Goren, S.; Erbas, C.; Akgun, T.; Uğurdağ, Hasan Fatih (Springer Nature, 2019-01)This paper describes flexible tools and techniques that can be used to efficiently design/generate quite a variety of hardware IP blocks for highly parameterized real-time video processing algorithms. The tools and techniques ... -
Tools and tecniques for implementation of real-time video processing algorithms
Levent, Vecdi Emre (2018-09)Hardware implementation of video processing algorithms, which are usually real-time by nature, need architectural exploration so that we achieve the required performance with minimal cost. In addition, the video algorithm ... -
Using deep compression on PyTorch models for autonomous systems
Doğan, Eren; Uğurdağ, Hasan Fatih; Ünlü, Hasan (IEEE, 2022)Applications of artificial neural networks on low-cost embedded systems and microcontrollers (MCUs), has recently been attracting more attention than ever. Since MCUs have limited memory capacity as well as limited ... -
Using eigenvoices and nearest-neighbours in HMM-based cross-lingual speaker adaptation with limited data
Sarfjoo, Seyyed Saeed (2017-08)Thesis abstract: Cross-lingual speaker adaptation for speech synthesis has many applications, such as use in speech-to-speech translation systems. Here, we focus on cross-lingual adaptation for statistical speech synthesis ... -
Using high-level synthesis for rapid design of video processing pipes
Güzel, Aydin Emre; Levent, Vecdi Emre; Tosun, Mustafa; Özkan, M. Akif; Akgun, T.; Büyükaydın, D.; Erbas, C.; Uğurdağ, Hasan Fatih (IEEE, 2016)In this work, we share our experience in using High-Level Synthesis (HLS) for rapid development of an optical flow design on FPGA. We have performed HLS using Vivado HLS as well as a HLS tool we have developed for the ... -
