Abstract:
1. A data processing apparatus comprising: a data sort block configured to sort, into multiple groups by information data of a same type, input data including information data of multiple types formed by multiple bits; a maximum value extraction block configured to extract a maximum value of said information data in each of said groups sorted by said data sort block; a bit position decision and bit reduction block configured to determine a reduction position of bits common to the information data of the same type in each group on the basis of said maximum value extracted by said maximum value extraction block and reduce said common bits in accordance with the determination; a most-significant-bit positional information output block configured to output most-significant-bit positional information indicative of a most significant setting bit position in information data indicative of said maximum value extracted by said maximum value extraction block; and a bit attachment/decompression block configured to determine a quantity of bits to be attached on the basis of said most-significant-bit positional information from said most-significant-bit positional information output block and attach bits to output data of said bit position decision and bit reduction block in accordance with said determination.
