CALCULATION DEVICE FOR HIGH SPEED PROCESS OF IMAGE DATA WHICH PROCESSES THE CALCULATION FOR COMPRESSING OR RECOVERING OF THE DIGITAL IMAGE IN PARALLEL

摘要

PURPOSE: A calculation device for high speed process of image data is provided to improve the performance by performing the block-based calculation through at least one among k adders, k subtractors and k multipliers.;CONSTITUTION: The first operation execution unit(810) and a plurality of the first operation blocks(810_1~810_K) are included. The second execution unit(820) includes a plurality of the second operation blocks(820 1~820 K). The first and the second operation blocks process the image data at the same time. The first and the second operation blocks perform the different calculation. The calculation is one among addition, subtraction and multiplication.;COPYRIGHT KIPO 2011
