<p>PROBLEM TO BE SOLVED: To attain speedup and increase in efficiency to transfer a bit plane or bit data especially of multi-valued data. SOLUTION: In a data processing apparatus, multi-valued data of 8 bits is stored into a memory 50 by 4 pieces per one word, then multi-valued data of 4 by 4=16 pieces is taken on a single processing unit (a processing block) of a bit plane coding. At memory area 51, the most significant bit (bit 7) of each multi-valued data (in Fig. 5, data 0 - data 15) is gathered in order of each multi-valued data to be stored at one place as shown by a batched part. A bit 6 is also stored in the same way.</p> |
