CPU design simplified
Yıldız, A.; Uğurdağ, Hasan Fatih; Aktemur, Tankut Barış; İskender, Deniz; Gören, S. (IEEE, 2018-12-10)The first goal of this paper is to introduce a simple and customizable soft CPU named VerySimpleCPU (VSCPU), which could be easily implemented on FPGAs with a complete toolchain including instruction set simulator, assembler, ... -
Crucial topics in computer architecture education and a survey of textbooks and papers
Yıldız, A.; Gören, S.; Uğurdağ, Hasan Fatih; Aktemur, B.; Akdoğan, Taylan (International Association of Engineers, 2020)We have been teaching undergraduate computer architecture since 2012 in an unconventional way. Most undergraduate computer architecture courses are based on microprocessors, and they quickly move into advanced topics such ... -
Enabling difference-based dynamic partial self reconfiguration for large differences
Gören, S.; Özkurt, Ö.; Türk, Y.; Yıldız, A.; Uğurdağ, Hasan Fatih (IEEE, 2013)This paper presents a new Dynamic Partial Self Reconfiguration (DPSR) flow for Xilinx FPGAs. Leveraging the Xilinx FPGA Editor and PlanAhead tools, we provide two implementation approaches that enable partial reconfiguration ... -
Fast and efficient implementation of lightweight crypto algorithm PRESENT on FPGA through processor instruction set extension
Varıcı, Abdullah; Sağlam, Gürol; İpek, Seçkin; Yıldız, A.; Gören, S.; Aysu, A.; İskender, Deniz; Aktemur, Tankut Barış; Uğurdağ, Hasan Fatih (IEEE, 2019)As Internet of Things (IoT) technology becomes widespread, the importance of information security increases. PRESENT algorithm is a major lightweight symmetric-key encryption algorithm for IoT devices. Compared to the ... -
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 ...
