Circuit for designating write and read address to provide a delay time in a sound system

摘要

A write address and a read address are generated by use of a pointer register and a single register set common to the write and read addresses. The read register is obtained by an addition or subtraction of a pointer value and a value selected from offset values of the register set, and the write register is obtained by adding one to the read address or subtracting one therefrom.
