Introduction
The STMicroelectronics STM32MP157 line microprocessors embed a Vivante GPU (graphics processor unit) that uses the
Khronos® Group OpenGL® ES (embedded system) and OpenVG™ standards.
This document describes the STM32MP157 GPU tool kit (STM32MP157GPUTK), a set of applications allowing developers to
rapidly develop and port graphic applications.
Thanks to STM32MP157GPUTK, any graphics-based application can be accelerated, improving the eye-catching visuals and
minimizing the system resources loading (CPU, memory, bandwidth, power).
Good understanding of OpenGL®/OpenGL® ES programming fundamentals, is recommended before reading this user manual.
See the related STM32MP157 documentation [1], [2] for more technical details.

1.1 STM32MP157GPUTK components overview
STM32MP157GPUTK includes the following components (also named vTools):
•vProfiler: driver and hardware performance profiling utility
•vAnalyzer: visual analyzer for graphing the performance metrics
The following pre-processing utilities are also provided:
•vShader for standalone development of optimized shader programs
•vCompiler for compiling shader code into binary executables
•vTexture for image transfer providing compression and decompression options
