RenderScript is 76 primarily oriented for use with data-parallel computation, although serial computationally intensive workloads can 77 benefit as well. 78 79 RenderScript **intrinsics** are built-in functions that perform well-defined operations often seen 80 in image processing. Intrinsics provide extremely high-performance implementations of standard 81 functions with a minimal amount of code. 82 83 This sample shows how to access and use the blur, convolve, and matrix intrinsics: 84 85 ```java 86 mScriptBlur = ScriptIntrinsicBlur.create(mRS, Element.U8_4(mRS)); 87 mScriptConvolve = ScriptIntrinsicConvolve5x5.create(mRS, 88 Element.U8_4(mRS)); 89 mScriptMatrix = ScriptIntrinsicColorMatrix.create(mRS, 90 Element.U8_4(mRS)); 91 ``` 92 93 RenderScript intrinsics will usually be the fastest possible way for a developer to perform these operations. The 94 Android team works closely with our partners to ensure that the intrinsics perform as fast as possible on their 95 architectures 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
