Fast one- and two-pick fixed-priority selection and muxing circuits

Tosun, Mustafa; Özkan, M. Akif; Güzel, Aydin Emre; Uğurdağ, Hasan Fatih (IEEE, 2016)

Priority encoders and arbiters usually drive multiplexers (muxes). Latency optimization of priority encoders and multiplexer trees has usually been handled separately in the literature. However, in some applications with ...
FPGA implementation of a dense optical flow algorithm using altera openCL SDK

Ulutaş, Umut; Tosun, Mustafa; Levent, Vecdi Emre; Büyükaydın, D.; Akgün, T.; Uğurdağ, Hasan Fatih (Springer International Publishing, 2017)

FPGA acceleration of compute-intensive algorithms is usually not regarded feasible because of the long Verilog or VHDL RTL design efforts they require. Data-parallel algorithms have an alternative platform for acceleration, ...
M-pick fixed-priority selection and muxing

Tosun, Mustafa (2017-01)

In this thesis, we propose a class of logic architectures for multi-pick (m-pick) fixed-priority arbitration (FPA) and muxing. An m-pick FPA selects the m topmost requests out of n inputs with priority order. Arbiters ...
Output domain downscaler

Büyükmıhçı, M.; Levent, Vecdi Emre; Guzel, Aydın Emre; Ates, Ozgur; Tosun, Mustafa; Akgün, T.; Erbas, C.; Gören, S.; Uğurdağ, Hasan Fatih (ISCIS 2016: Computer and Information Sciences, 2016)

This paper offers an area-efficient video downscaler hardware architecture, which we call Output Domain Downscaler (ODD). ODD is demonstrated through an implementation of the bilinear interpolation method combined with ...
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 ...
