FORMAT CONVERSION APPARATUS FROM BAND INTERLEAVE FORMAT TO BAND SEPARATE FORMAT

摘要

An apparatus for converting a band interleave format to a band separate format is provided to convert image data of the band interleave format into image data of the band separate format and perform SIMD(Single Instruction Multiple Data) mode processing after performing N partitioning of an ALU(Arithmetic and Logic Unit), thereby improving efficiency of image processing. A memory(310) stores image data of a band interleave format. A converting module reads the memory by increasing a read address of the memory as much as a stride, and converts the image data of the band interleave format into image data of a band separate format. The converting module comprises a memory controller(320) and a register filter(330). A data line(311) is branched into data lines(313,315,317,319) and respectively connected to registers(331,333,335,337) of the register file.
