RenderScript is 76primarily oriented for use with data-parallel computation, although serial computationally intensive workloads can 77benefit as well. 78 79RenderScript **intrinsics** are built-in functions that perform well-defined operations often seen 80in image processing. Intrinsics provide extremely high-performance implementations of standard 81functions with a minimal amount of code. 82 83This sample shows how to access and use the blur, convolve, and matrix intrinsics: 84 85```java 86mScriptBlur = ScriptIntrinsicBlur.create(mRS, Element.U8_4(mRS)); 87mScriptConvolve = ScriptIntrinsicConvolve5x5.create(mRS, 88 Element.U8_4(mRS)); 89mScriptMatrix = ScriptIntrinsicColorMatrix.create(mRS, 90 Element.U8_4(mRS)); 91``` 92 93RenderScript intrinsics will usually be the fastest possible way for a developer to perform these operations. The 94Android team works closely with our partners to ensure that the intrinsics perform as fast as possible on their 95architectures — often far beyond anything that can be achieved in a general-purpose language. 96 97[1]: http://developer.android.com/guide/topics/renderscript/compute.html 98]]> 99 </intro> 100 </metadata> 101</sample> 102
