    Demo: Real-time video frame differentiator based on external memory interface
    (IEEE Computer Society, 2018-08) Davutoğlu, Doğancan; Yıldız, Nerhun; Tavşanoğlu, Ahmet Vedat; Ayten, Umut Engin
    Implementation and demonstration processes of a real-time video frame differentiator based on an external memory interface is described in this paper. The video frame differentiation process is successfully implemented on both low cost and high-end FPGA development boards, then demonstrated by using sample videos at 1024x768@60 and 1920x1080@60 resolutions. Input video resolution, video buffer size on memory and burst size of the memory interface can be configured before implementation.

    Real-time frame buffer implementation based on external memory using FPGA
    (Elsevier B.V., 2018) Davutoğlu, Doğancan; Yıldız, Nerhun; Ayten, Umut Engin; Tavşanoğlu, Ahmet Vedat
    In this paper, design of a real-time video frame buffer with an external memory interface is proposed. In addition, simulation and implementation processes of the design is described. The mentioned system is able to buffer video signals up to 1920×1080 full-HD resolution at 60 Hz frame rate. The memory interface is designed based on an external SDRAM memory and supports burst read/write operations. Input video resolution, video buffer size on memory and burst size of the memory interface are user defined and can be configured.

    Real-time video frame differentiator based on DDR3 SDRAM memory interface
    (IEEE Computer Society, 2018-08) Davutoğlu, Doğancan; Yıldız, Nerhun; Tavşanoğlu, Ahmet Vedat; Ayten, Umut Engin
    In this paper, design of a real-time video frame differentiator based on an external memory interface is proposed. Furthermore, implementation and simulation processes of the design is discussed. The proposed design is capable of differentiating video frames over time, up to full-HD resolution at 60 Hz frame rate. An external SDRAM memory unit is used within the proposed design and drived by a memory interface. In order to improve the flexibility of the architecture, video resolution, video buffer size on memory and burst size of the memory interface are designed to be user defined and configurable.
