Abstract
An example embodiment provides a resizer in an image processing system. The resizer includes a receiving module that receives pixel data representative of an image. A triple line buffer is coupled to the receiving module that stores the pixel data in response to a write control signal from control logic. The triple line buffer is operated as a circular buffer. The resizer further includes a resizer core that reads pixel data from the triple line buffer in response to a read control signal from the control logic. The pixel data is replicated to up-scale the image vertically according to a vertical up-scale ratio such that the resizer achieves a maximum input data rate and also eliminates an overflow condition in the resizer. The vertical up-scale ratio is a fraction.
