Patent ID: 8451282

Claim:
An apparatus for accessing a plurality of image data, comprising: a FIFO memory for storing the image data, wherein the image data comprises a plurality of pixel data corresponding to a plurality of pixels respectively, the FIFO memory comprises a plurality of memory blocks, and each of the memory blocks comprises a plurality of memory units; and a controller for accessing the FIFO memory in circular manner; wherein the controller writes each of the pixel data of the image data into N memory blocks of the FIFO memory on a pixel-basis and reads the stored image data in channel-basis, and the stored image data are respectively read out to a plurality of output channels in a read clock cycle, and within one clock cycle of a read clock signal, the controller reads M bit-pair data of the stored image data from M memory blocks of the plurality of memory blocks of the FIFO memory to M output channels, respectively; the numbers N and M being positive integers greater than 1.
