The usage of the FPGA (Field Programmable Gate Array) for neural network implementation provides flexibility in programmable systems. For the neural network based instrument prototype in real time application, conventional specific VLSI neural chip design suffers the limitation in time and cost. With low precision artificial neural network design, FPGAs(More)
In modern computer systems (communication systems, military systems, medical applications, etc.) are sophisticated mathematical operations and trigonometric calculations widely used. CORDIC (Coordinate Rotation DIgital Computer) architecture should be used on digital computers to implement complex mathematical operations and trigonometric calculations. In(More)
Designing block ciphers targeting resource constrained 8-bit CPUs is a challenging problem. There are many recent lightweight ciphers designed for better performance in hardware. On the other hand, most software efficient lightweight ciphers either lack a security proof or have a low security margin. To fill the gap, we present RoadRunneR which is an(More)
“Movement of Enhancing Opportunities and Improving Technology”, abbreviated as Fatih, is among the most important educational projects in Turkey, in which students and teachers can use their tablet PCs to obtain educational data (text, images, media, etc.) stored in cloud servers. However, the limited network bandwidth and increase in both the(More)
For the integration of smart antennas into third generation code division multiple access (CDMA) base stations, it still remains as a challenging task to implement smart antenna algorithms on programmable processors. In this paper, we study implementations of some CDMA compatible beamforming algorithms, namely least mean square (LMS), constant modulus (CM),(More)
This article explains implementing of Fast Fourier (FFT) and Inverse Fast Fourier Transform algorithms(IFFT) in FPGA. The reason of designing the study on FPGA base is that FPGAs are able to rearrange of logical blocks and moreover, mathematical algorithms can confirm faster by means of parallel data processing. For operating these algorithms, it is used(More)
It is preferable for wireless operators to use the existing infrastructure as possible for different services such as GSM, 3G and Wimax. This becomes possible with the development of software defined base stations. But, to obtain desired performance and flexibility in signal processing at software defined base stations needs to be implemented instead of(More)
Image processing is used effectively in the medical field because of the convenience it brings to human life. Incorrect data which obtained during image processing operations in the medical area can have serious consequences. Therefore, the selection of the thresholding method used as pre-image processing step is also vital. In this study, comparison of(More)
"Movement of Enhancing Opportunities and Improving Technology", abbreviated as Faith, is among the most important educational projects in Turkey, in which students and teachers can use their tablet PCs to obtain educational data (text, images, media, etc.) stored in cloud servers. However, given the large number of users along with vast amount of(More)
