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.
