ABSTRACT:
An image data processing method and system receives image data from a burst memory buffer and provides output image data to a vertical filter for filtering. The method determines whether a new frame of input image data has been received, said frame of data having a plurality of blocks, each block having a plurality of rows and columns. A vertical input buffer uses a read pointer, an oldest unused data pointer, and a write pointer to keep track of the data that is being read and stored. Data is read and stored into said vertical input buffer by determining the minimum offset for the block, reading a row of input image data from the burst memory buffer and skipping the row depending on the minimum offset until minimum offset reached, and storing the row of input image data in said vertical input buffer for processing by the vertical filter until the buffer is full. If the entire frame has been processed then the pointers are all reset. If an entire column in the output image has been processed then the column data is flushed. In another embodiment, a low latency mode is adopted such that it is not necessary for the columns to be completely processed before switching to the next column horizontally.
