Abstract
An accelerator circuit for an image processing apparatus includes a buffer circuit that temporarily stores image data obtained from N (N>1) data sources and an arithmetic circuit that performs a predetermined arithmetic operation on pixel data. The buffer circuit includes N buffer memories and N 2D registers associated with the respective N data sources, a control circuit, and a selector. Each buffer memory temporarily stores image data obtained from a corresponding one of the N data sources. Each 2D register temporarily stores pixel data, which is a part of image data stored in a corresponding one of the N buffer memories, of an area of a predetermined size. The selector is controlled by the control circuit so as to select, when pixel data is stored in one of the N 2D registers, the pixel data and send the pixel data to the arithmetic circuit.
