DISTRIBUTED ARITHMETIC UNIT

摘要

a multi-input part(100) inputting 12 bit input pixel and performing the bit sequence conversion of the 8 pixel value; an one-dimensional converting part(200) performing the discrete cosine transforming of the output signal of the multi-input part; a 2 bit parallel bit sequential procession transforming part(300) performing the procession transform processing of the output signal of the one-dimensional converting part(200); an one-dimensional transform part(400) performing the discrete cosine transform operation of the output signal of the 2 bit parallel bit sequential procession transforming part(300); and an output part(500) outputting the output signal of the one-dimensional transform part(400) as 12 bit parallel data.
