DATA PROCESSING APPARATUS AND IMAGE PROCESSING APPARATUS
First Claim
1. A data processing apparatus comprising:
- a buffer unit that stores data;
a data write control unit that writes input data to the buffer unit;
a data read control unit that reads the data stored in the buffer unit, the data read control unit outputting output data generated based on the read data; and
a buffer area determination unit that determines a storage area within the buffer unit to which the data write control unit writes the data and a storage area within the buffer unit from which the data read control unit reads the data, and whereinthe data write control unit writes the input data to the storage area determined by the buffer area determination unit, and outputs a data write completion signal indicating that the writing of the data is completed when the writing of the input data is completed, andthe data read control unit reads the data from the storage area determined by the buffer area determination unit, and outputs a data read completion signal indicating that the reading of the data is completed when the output of the output data generated based on the read data is completed.

Abstract
A data processing apparatus may include a buffer unit, a data write control unit, a data read control unit, and a buffer area determination unit. The data write control unit may write the input data to the storage area determined by the buffer area determination unit, and output a data write completion signal indicating that the writing of the data is completed when the writing of the input data is completed. The data read control unit may read the data from the storage area determined by the buffer area determination unit, and output a data read completion signal indicating that the reading of the data is completed when the output of the output data generated based on the read data is completed.

6. An image processing apparatus comprising a data processing apparatus, the data processing apparatus comprising:
-
a buffer unit that stores data; a data write control unit that writes input data to the buffer unit; a data read control unit that reads the data stored in the buffer unit, the data read control unit outputting output data generated based on the read data; and a buffer area determination unit that determines a storage area within the buffer unit to which the data write control unit writes the data and a storage area within the buffer unit from which the data read control unit reads the data, and wherein the data write control unit writes the input data to the storage area determined by the buffer area determination unit, and outputs a data write completion signal indicating that the writing of the data is completed when the writing of the input data is completed, the data read control unit reads the data from the storage area determined by the buffer area determination unit, and outputs a data read completion signal indicating that the reading of the data is completed when the output of the output data generated based on the read data is completed, the data write control unit performs settings related to writing of image data after the data write completion signal is output, and the data read control unit performs settings related to reading of the image data after the data read completion signal is output.
