    Design of data buffers in field programmablr gate arrays
    (National Technical University of Ukraine "Igor Sikorsky Kyiv Polytechnic Institute", 2022) Sergiyenko, Anatoliy; Serhiienko, Pavlo; Mozghovyi, Ivan; Molchanova, Anastasiia
    The design of the data buffers for the field programable gate array (FPGA) projects is considered. A new method of buffer design is proposed, which is based on the representation of the synchronous dataflow graph in the three-dimensional space, optimization of them, and description in VHDL. The method gives the optimized buffers which are based either on RAM or on the register pipeline. The derived pipeline buffer can be mapped into the shift register primitive of FPGA. The method is built in the experimental SDFCAD framework intended for the pipelined datapath synthesis.

    GIF image hardware compressors
    (National Technical University of Ukraine "Igor Sikorsky Kyiv Polytechnic Institute", 2021) Mozghovyi, Ivan; Sergiyenko, Anatoliy; Yershov, Roman
    Increasing requirements for data transfer and storage is one of the crucial questions now. There are several ways of high-speed data transmission, but they meet limited requirements applied to their narrowly focused specific target. The data compression approach gives the solution to the problems of high-speed transfer and low-volume data storage. This paper is devoted to the compression of GIF images, using a modified LZW algorithm with a tree-based dictionary. It has led to a decrease in lookup time and an increase in the speed of data compression, and in turn, allows developing the method of constructing a hardware compression accelerator during the future research.
