3.1 Introduction

GPUs in mobile devices today are becoming increasingly powerful. The biggest

concern in the mobile space is battery life and one of the biggest consumers of

battery is external memory access. Modern mobile games use post-processing

effects in various ways and while the GPU itself is capable of doing this, the

bandwidth available to the GPU is typically not.

A major strength of Mali and other tile-based architectures is that a lot of

operations can be performed on-chip without having to access external memory.

For an application to run efficiently on such architectures it is b
