"discrete cosine transform JPG science"
Here's a more interesting link directly from the app developers: http://www.snappylabs.com/blog/snappycam/2013/07/31/iphone-king-of-speed/ http://www.snappylabs.com/blog/snappycam/2013/07/31/iphone-k...
- Strilanc 13y agoThanks, 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.

- stefantalpalaru 13y agoThe Android bashing in that article is unfounded: http://www.eggwall.com/2011/09/android-arm-assembly-calling-assembly.html http://www.eggwall.com/2011/09/android-arm-assembly-calling-...
- nl 13y agoIt'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..
- stefantalpalaru 13y agoHe 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?
- nl 13y agoUmm.. it shows the power of software optimisation?
