Abstract
A data processing circuit able to absorb jitter due to differences in operating frequencies between applications by a small-sized and inexpensive configuration when connecting a plurality of applications operating at various frequencies, including a DRAM and a memory controller which writes a digital audio signal input from a DSP into the DRAM on the basis of a clock signal from the DSP , then reads it out on the basis of a clock signal set for a D/A converter and outputs it to the D/A converter. Jitter absorption is achieved through a buffering scheme.
