    摘要: According to one embodiment, an image processing apparatus connected to an external memory and a cache memory. The apparatus includes a counter, a coordinate calculator, a tag checker, a pixel referring module, a pixel value calculator and an outputting module. The counter determines a converted coordinate according to a predetermined execution sequence. The coordinate calculator calculates a unconverted coordinate used to calculate a converted pixel value located at the converted coordinate. The tag checker generates a conversion request to calculate the converted pixel value with reference to an unconverted pixel located at the unconverted coordinate. The pixel referring module reads the unconverted pixel from the cache memory based on the conversion request when the unconverted pixel is stored in the cache memory. The pixel value calculator calculates the converted pixel value with reference to the read unconverted pixel. The outputting module writes the converted pixel having the calculated converted pixel value into the external memory.
