Title:
DATA CONVERTING METHOD AND ITS DEVICE
Document Type and Number:
Japanese Patent JP3675948
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a data converting method and its device efficiently converting data through the use of a single buffer memory by writing only valid data after arithmetic processing in a buffer memory.
SOLUTION: This device arithmetically processes a prescribed number of consecutive data regarding as one block with an arithmetic unit 2 to reduce the number of the data to 1/2n (n is an integer) and outputs data after the arithmetic through the buffer memory 8. In this case, data obtained by arithmetic processing is shifted by the number of data (2n-1) by means of shift registers 3 to 5, and this data shifted by the number of data (2n-1) and arithmetic- processed data of the next block are made a pair to be successively written in the single buffer memory 8 by means of latch circuits 6 and 7.
