Embodiment Construction

[0025] Figure 4 It is a schematic diagram showing a drawing system according to the present invention. The graphics system 40 includes an integrated graphics chip 42 , an external graphics card 44 and a system memory 46 . The system memory 46 can be various types of integrated circuit memory, such as static random access memory (SRAM), dynamic random access memory (DRAM), or cache memory. Figure 5 Indicates the graphics processing performed by the integrated graphics chip 42 and the external graphics card 44 of the graphics system 40 . Such as Figure 5 As shown, the drawing processing carried out by the integrated graphics chip 42 is the same as figure 2 The illustrated graphics processing pipeline is the same, including a vertex shader 421 , a clip and setup processor 422 and a pixel shader 423 . Vertex shader 421 performs figure 2 Coordinate transformation and lighting processing described in step S22. The pruning and setting processor 422 is responsible for fig...

Abstract

The invention is a drawing system, comprising a first drawing device and a second one, where the first one comprises cutting and setting processor and pixel colorizer, where the cutting and setting processor accesses and cuts drawing data and the pixel colorizer colorizes the cut drawing data, and the second one is removably arranged at the first one, does not comprises the processor and colorizer but comprises a first vertex colorizer to make coordinate conversion and illumination processing on vertex data so as to output the drawing data.

Description

technical field [0001] The invention relates to a drawing device and a drawing control method; in particular, it relates to a drawing device and a drawing control method which saves cost and improves performance. Background technique [0002] As the complexity and fidelity of graphics applications increase, the capabilities of computing platforms, including microprocessor speed, system memory capacity and bandwidth, and multitasking, continue to advance. In order to meet the requirements of modern graphics applications, graphics devices (also called graphics accelerators) have become one of the integrated components in modern computer systems. [0003] figure 1 Shown is a schematic diagram of a conventional graphics system 10 using an add-on graphics card. The graphics system 10 includes a control chipset 14 , a system memory 16 and an add-on graphics card 18 . Drawing data is sent to graphics card 18 from a central processing unit 12 through a control chipset 14 and a bu...
