+<h3>Renderscript</h3>
+
+<div>
+
+<p><a href="http://developer.android.com/guide/topics/renderscript/index.html">Renderscript</a>
+   is Android's advanced 3D graphics rendering and compute API. It provides a
+   portable C99-based language with extensions to facilitate common use cases
+   for enhancing graphics and thread level parallelism. The Renderscript
+   compiler frontend is based on Clang/LLVM. It emits a portable bitcode format
+   for the actual compiled script code, as well as reflects a Java interface for
+   developers to control the execution of the compiled bitcode. Executable
+   machine code is then generated from this bitcode by an LLVM backend on the
+   device. Renderscript is thus able to provide a mechanism by which Android
+   developers can improve performance of their applications while retaining
+   portability.</p>
