Data transfer device

摘要

A data transfer device includes a FIFO memory and a control unit which obtains a data amount of the FIFO memory to control the FIFO memory and outputs a selection signal corresponding to the obtained data amount of the FIFO memory. An output data generation unit generates output data including either one of the second output data and an interpolation data selected based on the selection signal, and a first output data stored in a frame memory.

1. A data transfer device, comprising:
a first storage unit in which first data output from a memory is sequentially stored and from which first output data is output in a sequence corresponding to a storage sequence of the first data; a first control unit which obtains a data amount of the first storage unit and controls the first storage unit according to the data amount of the first storage unit; a second storage unit in which second data output from the memory is sequentially stored and from which second output data is output in a sequence corresponding to a storage sequence of the second data; a second control unit which obtains a data amount of the second storage unit, controls the second storage unit according to the data amount of the second storage unit and outputs a selection signal corresponding to the data amount of the second storage unit; an interpolation data generation unit which generates interpolation data based on the first output data; and an output data generation unit which alternately outputs the first output data and the second output data when the selection signal is of a first level and alternately outputs the first output data and the interpolation data when the selection signal is of a second level.
