Apparatus for decoding image data based on availability of reference data and method thereof

摘要

An image data decoding apparatus and method are based on an availability of reference data. The image data decoding apparatus may include a core to process decoding of image data, and an availability determining device to receive, from the core, availability verification request information with respect to a reference area of a first frame included in the image data, to determine an availability with respect to the reference area based on the received availability verification request information, and to transmit, to the core, the determined availability. When the reference area is available, the core may process decoding of a second frame based on the reference area.

主权项

1. An apparatus to decode an image, comprising:
a plurality of cores to process decoding of image data; an availability information storage device to store availability information comprising a plurality of bits, wherein each bit of the plurality of bits corresponds to each macro block of a plurality of macro blocks of a frame, and each bit of the plurality of bits indicates whether each corresponding macro block of the frame is decoded; and a processor comprising: an availability determining device to receive, from the plurality of cores, availability verification request information with respect to a reference area of a first frame included in the image data, to determine an availability of the reference area based on the received availability verification request information, and to transmit, to the plurality of cores, the determined availability, wherein, when decoding of a macro block is completed, the plurality of cores requests an update of the availability information based on the macro block of which decoding is completed, and the availability determining device updates the availability information in response to the received request for update, and wherein, when the reference area is available, the plurality of cores processes decoding of a second frame in the image data based on the reference area.
