24.7. Warp Lite IP Line Store

The Warp Lite IP uses an on-chip RAM line store to provide the random access required when applying the inverse mapping from the output space to the input space. The maximum distortion, maximum line width, and number of bits per symbol determine the size of this line store.

The line store stores a fixed number of input lines at any one time. The IP configures the line store as dual-port RAM. The number of lines depends on the maximum distortion and the maximum resolution width. You select the required distortion from the configuration parameters.
