| [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. |
