    Abstract: Provided are a stream reprocessing system on chip (SoC) and a method for operating the same is provided. The stream reprocessing system includes a plurality of processors including a central processing unit (CPU); a memory controller configured to receive a stream; and a stream reprocessor configured to perform reprocessing the stream, wherein the stream reprocessor includes: a control unit configured to determine whether to perform the reprocessing on the stream; a reprocessing unit configured to reprocess the stream based on receiving a command to perform the reprocessing on the stream from the control unit; and an output unit configured to transmit the reprocessed stream to a memory.

    Abstract: An image processing device for performing a data decompression is provided. The image processing device includes a decoder circuit having a plurality of stages for decompressing compressed image data of a plurality of pixels. The decoder circuit is configured to divide the pixels into a plurality of groups. The first stage performs prediction compensation on the compressed image data of a first pixel of the first group at a first time to generate first prediction data, and performs the prediction compensation on the compressed image data of a second pixel of the first group at a second time using the first prediction data. The second stage performs the prediction compensation on the compressed image data of a first pixel of the second group at the second time using the first prediction data, to generate second prediction data.

    Abstract: An image processing device includes a frame buffer compressor, which is configured to: (i) compress source data into compressed data having CRC bits appended thereto, and (ii) decompress the compressed data into output data and use the CRC bits to check for errors in the output data. A multimedia device is provided, which is configured to generate the source data in response to raw data. A memory device is provided, which is configured to store the compressed data. The frame buffer compressor may include an encoder configured to compress the source data into the compressed data with the CRC bits appended thereto, and a decoder configured to decompress the compressed data into the output data. The encoder may include a prediction module, which is configured to generate prediction data including reference data and residual data, from the source data.
