RenderScript: parallel computing on Android, the easy way
RenderScript: parallel computing on Android, the easy way provides a straightforward way to learn how to use the RenderScript parallel computing framework.
This is the first book on the market that covers as many RenderScript related topics as possible!
Basic and advanced topics are treated, ranging from parallel computing Kernels to the Android NDK integration, covering many aspects of RenderScript and targeting both newcomers and experienced users.
A general list of the treated topics is as follows:
What is RenderScript, a general description of the framework.
RenderScript components, like Kernels and Allocations.
Performance notes, where different ways to perform calculations are benchmarked.
Native analysis, or “what is under the hood”.
RenderScript and NDK, how to use the Android NDK together with RenderScript.
Use cases, some examples of RenderScript usage.
Porting case – FAST features detection, a big example that shows how to port a C++ library to work inside RenderScript kernels.
RenderScript gives users the chance to unleash the true computing power of Android-based devices, helping them to develop calculation-intensive apps: the objective of this book is to spread the word about this beautiful framework, by showing how easy it is to transform the common CPU-intensive code to the more useful parallel one.
Some possible applications of RenderScript are:
Wearable devices raw signals analysis, like Electromyography data and Electroencephalography data.
Advanced image processing, like Multi Face Detection and Recognition and visual features extraction.
Neural networks testing on mobile-phones, which requires a large number of parallel processes.
Digital Signal Processing (e.g. sound analysis).
Alberto Marchetti is a hard-times developer, born to solve coding problems. He started working in the software development field when he was a child. Since then, learning to find solutions to every possible development problem, has become his way of living life. When he discovered RenderScript, he found a beautiful tool that could help every developer to solve even more problems. That’s why he decided to write this book.
