Abstract
A data processing apparatus includes a channel demultiplexing circuit, a bus, a memory controller and a memory. The channel demultiplexing circuit has a first delay circuit which delays first channel data only of multi-channel data by one cycle and outputs first delayed channel data, a second delay circuit which delays second channel data only of the multi-channel data by one cycle and outputs second delayed channel data, and a channel data holding circuit which stores first coupled data obtained by coupling the first channel data and the first delayed channel data for multiple cycles and stores second coupled data obtained by coupling the second channel data and an output of the second delay circuit for multiple cycles. The channel demultiplexing circuit selectively outputs a first channel data group and a second channel data group to the bus.
