Do Understand the Target Device

Seek to learn as much information about the target platforms as possible in order to understand different graphics architectures, to use the device in the most efficient manner possible.

Manufacturers’ websites for devices are a good place to look for specifications and they may also provide other helpful developer community resources. The PowerVR Graphics SDK provides public architecture and performance recommendation documents for reference:

• PowerVR Architecture Overview

• PowerVR Performance Recommendations

• PowerVR Low Level GLSL Optimisation

• PowerVR Instruction Set Reference

Note

Further PowerVR architecture documentation is available from us under a non-disclosure agreement.

Even after the graphics architecture is thoroughly understood, it is important to remember that other factors such as variations in CPU processing power, memory bandwidth, and thermal load will also impact an application’s performance.
