Image Forming Apparatus, Memory Control Device and FIFO Memory Control Method

摘要

An image forming apparatus of the invention includes a memory circuit having plural FIFO memories connected in parallel, an image data generating unit that supplies image data formed of plural lines to the memory circuit, and a line counter that counts the number of lines of the image data supplied to the memory circuit. Moreover, the image forming apparatus includes a memory access control circuit that controls writing of the image data in the plural FIFO memories and periodically writes the image data sequentially supplied in the plural FIFO memories by shifting each of the image data by one line according to a count value of the line counter and an output selection circuit that simultaneously outputs a group of image data read out from the plural FIFO memories and rearranges the group of image data in order for each line according to a count value of the line counter to output the group of image data.
