Abstract
The invention is a method and apparatus for processing image data stored in a memory. A read interface circuit is coupled to the memory to transfer a patch of the image data from the memory to a buffer. A scale filter is coupled to the read interface circuit to scale the image data in the patch from the buffer. A receive circuit is coupled to the scale filter to re-organize the scaled image data.
Claims13
A method comprising:
- transferring a patch of the image data from a memory to a buffer, the image data being field separated in the memory, the transferring comprising:
- re-ordering the image data by merging the field separated image data,
- transposing the re-ordered image data, and
- storing one of the transposed image data and the image data in the buffer;
- scaling the image data in the patch;
- re-organizing the scaled image data;
- organizing the image data in the buffer to serial stream;
- and
- writing the re-organized scaled data to the memory.

A method comprising:
- transferring a patch of the image data from a memory to a buffer;
- scaling the image data in the patch;
- re-organizing the scaled image data, the re-organizing comprising converting the scaled image data into serial scaled image data;
- organizing the image data in the buffer to serial stream;
- and
- writing the re-organized scaled data to the memory, the writing comprising:
- storing the serial scaled image data into a write buffer, and
- transposing the stored image data from the write buffer.
