In other news, Google updates Renderscript for Android 4.2, probably the major update in this release the improved performance of common image-processing operations with Renderscript.

"We made a few major improvements between ICS and Jelly Bean, which significantly reduced the overhead of short scripts as well as the cost of getting elements out of allocations. Going from Android 4.1 to Android 4.2, we added a number of performance improvements to the math library. Our hardware partners also made major contributions; ARM in particular provided numerous compiler improvements which greatly improved our ability to generate vector code," Google explains.

To learn more about using Renderscript, see the Renderscript Computation developer's guide.

Renderscript image-processing benchmarks run on different Android platform versions (Android 4.0, 4.1, and 4.2) in CPU only on a Galaxy Nexus device.
