ELECTRONIC APPARATUS AND METHOD FOR DESIGNING MULTI-FORMAT DECODER

摘要

Disclosed are a method of designing to transform an a single-format decoder, which performs image processing on an image signal using a first codec, to a multi-format decoder, which performs image processing on an image signal using a second codec, and an electronic apparatus thereof. The method includes processing first information about the first codec and second information about the second codec to produce a first transform coefficient associated with the first codec and a second transform coefficient associated with the second codec, through a predetermined transform method; determining a similarity between the first transform coefficient associated with the first codec and the second transform coefficient associated with the second codec; and converting the single-format decoder to the multi-format decoder by adding at least one of a shifter, an adder, and a subtractor, based on the determined similarity. Consequently, a reduction in chip size and cost may be achieved.
