Abstract: An apparatus and a method for video frame rotation are provided. The apparatus includes a synchronous dynamic random access memory (SDRAM) and a video rotation circuit. The video rotation circuit is coupled to the SDRAM. The video rotation circuit sequentially writes a plurality of pixels of a video frame into the SDRAM in a row-by-row scanning manner. The video rotation circuit divides a plurality of columns of the video frame into a plurality of column sets, so as to divide each of the rows of the video frame into a plurality of sub-rows. The video rotation circuit performs an internal column-set scanning for each of the column sets in a column-set-by-column-set manner, so as to discretely read the sub-rows from the SDRAM.

Abstract: An interrupt management system and a management method thereof are provided. The interrupt management system includes a processor and an interrupt signal expanding controller. The processor receives a plurality of original interrupt signals. The interrupt signal expanding controller includes a decoder and an interrupt vector table. The decoder receives a plurality of expanding interrupt request signals, and decodes the expanding interrupt request signals to generate the original interrupt signals, where number of the expanding interrupt request signals is larger than number of the original interrupt signals. The interrupt vector table stores a plurality of interrupt vectors. The decoder reads one of the interrupt vectors to obtain an accessed interrupt vector according to the expanding interrupt request signals, and the interrupt signal expanding controller transmits the accessed interrupt vector to the processor.
