Figure 1 Instruction stream cloud phone architecture

The instruction stream engine consists of the server and client. The server provides functions such as OpenGL ES instruction interception and rendering separation, and the client provides functions such as OpenGL ES instruction execution.

**Table 1** Functions of the instruction stream modules
Module	Function
Rendering separation	Intercepts and encodes OpenGL ES instructions, maintains the OpenGL ES state machine, and rebuilds the rendering state machine.
Resource optimization	Implements delayed resource loading, texture compression, texture data video encoding, and instruction compression.
Rendering execution	Decodes and executes OpenGL ES instructions.
Resource restoration	Implements texture restoration, texture data video decoding, and instruction decompression.
Audio data collection	Obtains audio data and outputs audio data in OPUS or PCM format.
Audio decoding	Decodes and plays audio data in OPUS or PCM format.
Touch data distribution	Injects touch data into the Android cloud phone on the server.
Touch data collection	Obtains touch data.
Transmission adaptation	Performs cross-process data transmission and network transmission.
