Problems solved by technology

However, most of the current graphics processing units use the Immediate Rendering Architecture (IRA) to render the entire scene one by one. Since the direct rendering architecture starts to execute tasks directly after receiving each rendering command, its rendering speed is fast. However, since the data in the cache memory will be replaced frequently, the data flow of the memory access unit will increase significantly.

Abstract

A computer system and a drawing processing method thereof are disclosed. The drawing processing method being adapted to a drawing processing unit, and comprising: receiving a first instruction with respect to all rendering objects from a display driver by using a command stream parser; determining a size and a position of a plurality of blocks in each frame by a display driver; repeatedly performing drawing processing on each block according to the first instruction by the clipping loop unit of the command stream parser; comparing the signature of the current block corresponding to the currentframe with the signature of the block at the same position corresponding to the previous frame by a signature comparison unit of the cache memory, and generating a comparison result; and determiningwhether to refresh the update data corresponding to the current block located in the cache memory into the memory access unit according to the comparison result. The invention can reduce unnecessary data refresh times, thereby reducing the data flow of the memory access unit.

Description

technical field [0001] The present invention relates to a computer system and its drawing processing method, in particular to a computer system capable of reducing memory data flow and its drawing processing method. Background technique [0002] Graphics Processing Unit (GPU) is a very important computing element. However, most of the current graphics processing units use the Immediate Rendering Architecture (IRA) to render the entire scene one by one. Since the direct rendering architecture starts to execute tasks directly after receiving each rendering command, its rendering speed is fast. However, since the data in the cache memory will be replaced frequently, the data traffic of the memory access unit will increase significantly. Therefore, how to reduce the data flow of the memory access unit when executing the drawing task is a problem to be solved at present. Contents of the invention [0003] An embodiment of the present invention provides a graphics processing m...
