Abstract
Video processors and memory management methods thereof are provided, wherein the video processor is controlled by a central processing unit, and is coupled to a system memory to receive a macroblock. The video processor has two local memories, a control circuit and an image processing unit. The control circuit divides the macroblock into pixel segments, and disposes the pixel segments in the two local memories. The image processing unit accesses the two local memories for executing an image processing procedure. The system memory is refreshed by a processed macroblock in the two local memories.

A video processor, controlled by a central processing unit and coupled to a system memory to receive a macroblock, comprising:
- a first local memory;
- a second local memory;
- a control circuit, dividing the macroblock into pixel segments and disposing the pixel segments for storing in the first and second local memories;
- and
- an image processing unit, accessing the first and second local memories for executing an image processing procedure,
- wherein the system memory is refreshed by an processed macroblock stored in the first and second local memories.
A video processing method, comprising:
- retrieving a macroblock from a system memory;
- dividing the macroblock into pixel segments to dispose for a first and a second local memory;
- accessing the first and second local memories for executing an image processing procedure;
- and
- refreshing the system memory by a processed macroblock in the first and second local memories.
