Abstract

This article discloses an image processing circuit capable of fetching source data from a source memory area and writing the source data into a destination memory area on bit boundary basis with any angle. Fig. 1 shows source data fetched from the source memory area 1 shown in Fig. 2, destination data fetched from a destination memory area 2 into which the source data is written, and a mask pattern for controlling the write operation with an angle A. The source data could be fetched from the source memory area 1 on the bit boundary basis. The source data with any length could be fetched. The exemplary source data has one byte length and is called one-byte source data.
