| Abstract(in English) | In embedded systems, approximate computing can strongly promote reduction of execution time and energy consumption in exchange for some output errors. We focused on “Fuzzy memoization”, which is one of the approximate computing techniques. We improved it by using simplifying multiplication. By this improvement, we have developed a novel technique to reduce execution time and energy consumption while keeping output precision. Then, we implemented an application for grayscale filters on the Zynq system that contains ARM-based processor and field-programmable gate array (FPGA). As a result, this system could reduce the execution time by up to 28% and reduce the energy consumption by 11% in spite of very high-quality output images. |
