Abstract

PURPOSE: To enable the effective use of memory, by sectioning the capacity of memory to a given length and performing circulating memory for each part while keeping a given relation.
CONSTITUTION: The memory storage capacity is divided into the capacities M0W M3 different in lenght as 1, 3, 5, 7, for interleaving the data at the locations of h0Wh3, and the data is written to the memory while keeping the relation of length constant and the divided points aWd circulating in the memory, and also read out. In this case, the counters 18 and 20 equal to the total memory capacity 2N of the memory 5 are provided, the clock pulses fW and fR for write-in and readout are counted 18 and 20, and 0, 3, 8, 15 and 0, 1, 4, 9 are added 19, 21 in circulation manner to each count output to enable desired interleaving for each divided point while being circulated in the memory 5.
