[RenderScript][1] is a framework for running computationally intensive tasks at high performance on
Android. RenderScript is primarily oriented for use with data-parallel computation, although serial
computationally intensive workloads can benefit as well.

RenderScript **intrinsics** are built-in functions that perform well-defined operations often seen
in image processing. Intrinsics provide extremely high-performance implementations of standard
functions with a minimal amount of code.

This sample shows how to access and use the blur, convolve, and matrix intrinsics:

```java
mScriptBlur = ScriptIntrinsicBlur.create(mRS, Element.U8_4(mRS));
mScriptConvolve = ScriptIntrinsicConvolve5x5.create(mRS,
        Element.U8_4(mRS));
mScriptMatrix = ScriptIntrinsicColorMatrix.create(mRS,
        Element.U8_4(mRS));
```

RenderScript intrinsics will usually be the fastest possible way for a developer to perform these
operations. The Android team works closely with our partners to ensure that the intrinsics perform
as fast as possible on their architectures — often far beyond anything that can be achieved in a
general-purpose language.
