Abstract
An adaptive filter is adjustable for performing scaling operations. During a scaling operation, the adaptive filter stores scaled data in a memory such that more data samples may be retrieved during a subsequent scaling operation. The size of a finite impulse response filter used during the subsequent scaling operation may be adjusted to access the additional data samples.
Claims18
A method comprising:
- scaling a first portion and a second portion of image information to provide a scaled first portion and a scaled second portion that fit entirely within an addressable first memory area, wherein unscaled said first portion would substantially fill the first memory area;
- and
- storing said scaled first portion and said scaled second portion entirely in said first memory area.
A system comprising:
- a memory comprising a number of bytes;
- a scaler to perform a scaling operation, the scaling operation identifiable by a scaling ratio, wherein the scaler scales a first portion and a second portion of image information to provide a scaled first portion and a scaled second portion that fit entirely within addressable two-memory area, and unscaled said first portion would substantially fill the first memory area;
- and
- a memory controller coupled to the memory to store said scaled first portion and said scaled second portion entirely in said first memory area.
1 more element
An article comprising a medium storing instructions that, if executed, enable a processor-based system to:
- scale a first portion and a second portion of image information to provide a scaled first portion and a scaled second portion that fit entirely within an addressable first memory area, wherein unscaled said first portion would substantially fill a first memory area;
- and
- store said scaled first portion and said scaled second portion entirely in said first memory area.
