Thanks, that's a much better article.

> extended some of that research to create a new algorithm

> 10,000 lines of hand-tuned assembly code

> optimized out pipeline bubbles using a cycle counter tool

Color me impressed. It sounds like they really pulled out all the stops.

The Android bashing in that article is unfounded: http://www.eggwall.com/2011/09/android-arm-assembly-calling-...

It's not Android bashing - he's managed to make the older, slower iPhone hardware perform better than the current high-performance kings (the S3 & S4) through smart software optimisation.

There's no reason he couldn't do the same on Android and see similar gains. It would just be a lot of work..

He only implemented his optimized software on one platform and somehow starts to compare it with different software on another platform. How is that relevant for that other platform's performance?

Umm.. it shows the power of software optimisation?
