Abstract:
1. A buffering method comprising: (a) selecting a first buffer from at least two buffers as a buffer in which data corresponding to a row of a block of an image is to be written, based on a signal indicating the state of each of the at least two buffers; (b) selecting a second buffer, corresponding to an address, from the at least two buffers as a buffer from which data corresponding to another row of the block of the image is to be read; and (c) writing the data corresponding to the row of the block of the image in the first buffer and outputting the data corresponding to the other row of the block of the image stored in the second buffer according to the selections made in (a) and (b); and performing horizontal padding by freezing the address, wherein the signal indicating the state of each of the at least two buffers comprises at least two bits.
