Embodiment Construction

[0024] refer to figure 1 , provides a schematic structural diagram of an existing SOC system on chip, including an application processor 101, a 2D graphics processor 102, and a 3D graphics processor 103, and the 3D graphics processor 103 and the 2D graphics processor 102 communicate with each other through a data bus. The application processor 101 is coupled.

[0025] With the enhancement of processing capability and flexibility of 3D GPU, more and more data is put into 3D GPU for execution, including data traditionally processed by 2D GPU, such as daily window operation interface, etc., a large number of 2D The data is ported to run on the 3D GPU, and the 2D data is called through the 3D API. However, when the existing 3D GPU is used to process 2D data, processing resources are not fully utilized, which also results in high power consumption.

[0026] In the embodiment of the present invention, the application processor sends the graphics data corresponding to the graphics ...

Abstract

An embedded SOC (System on Chip) comprises a first graphics processing unit, a second graphics processing unit and an application processor. The first graphics processing unit is suitable for processing graphic data of graphics processing software of which the proportion of 2D graphics data is greater than a preset value. The second graphics processing unit is suitable for processing graphic data of graphics processing software of which the proportion of 2D graphics data is smaller than a preset value. The application processor is coupled to the first graphics processing unit and the second graphics processing unit, and is suitable for sending to-be-processed graphic data of graphics processing software to the first graphics processing unit or the second graphics processing unit according to a preset mapping relationship between graphics processing software and the graphics processing units. By using the SOC, the power consumption of 2D graphics data processing using a 3D graphics processing unit can be reduced effectively.

Description

technical field [0001] The invention relates to the computer field, in particular to an embedded SOC system on chip. Background technique [0002] A graphics processing unit (Graphics Processing Unit, GPU) is more suitable for graphics drawing than a central processing unit (Central Processing Unit, CPU), and has higher performance and better energy consumption efficiency. A GPU is usually integrated in an existing system on chip (System On Chip, SOC). [0003] According to different processing contents, GPUs can generally be divided into two-dimensional (2D) GPUs and three-dimensional (3D) GPUs. 2D GPUs are optimized for 2D images, and 3D GPUs are optimized for 3D images. Different GPUs process their corresponding data and have better energy efficiency. A 2D GPU and a 3D GPU are usually integrated in a SOC, and a 2D application programming interface (Application Programming Interface, API) and a 3D API are respectively used to call corresponding processing data. [0004]...
