HIGH SPEED PROCESSING METHOD FOR IMAGE DATA USING PARALLEL PROCESSORS ON GRAPHICS PROCESSING UNIT

摘要

PURPOSE: A high speed image processing method using a parallel processor of a wide use traffic processing device is provided to rapidly process high-capacity calculation process work by a software method. CONSTITUTION: A high speed image processing method using a parallel processor of a wide use traffic processing device is as follows: a step of separating a data space which will be updated from data space which will be referred and duplicating input data to a device area in a CPU side host area by establishing a multi memory buffer structure in GPU(Graphics Processing Unit) side device area, a step of performing calculation of reverse conversion or DWT by executing kernels in the GPU.
