Abstract

PURPOSE:To eliminate the need for an ROM and to reduce power consumption by using an adder. CONSTITUTION:To indicate a value leading values shown by memory address counters 11A-11C by the numeral of the counter 11A, the low-order three-bit value of the counter 11A is subtracted from the high-order four-bit value of the counter 11C. At this time, the deciding circuit 14 consisting of OR gates 14A and 14C and an AND gate 14B judges whether the indicated address is imputted to the additional memory or not to decide on whether the output of an adder 12 is outputted as it is or after 1 is added to the two bits of the output, thus performing accurate interleaving.
