Android :: Getting Hardware Floating Point With NDK

View 1 Replies View RelatedAndroid :: OpenGL ES Fixed - Floating Point
Oct 13, 2009I've started developing an OpenGL ES app and I would like to get the best possible performace (as everybody, I guess).
As far as I know, HTC Magic (myTouch, G2) doesn't have floating point unit, so I think every calculation is done internally with fixed point math. That beign the case, altough I fed OpenGL with floating point vertex positions and normals, there would not be any permormace penalty since it would be using integer math instead of floating point emulation.
Android :: Floating Point Support On G1 Phone
May 17, 2009I have been searching about the floating point support on G1 phone (aka the HTC Dream phone) for a few hours.
So far, my conclusion is that the ARM-based Qualcomm MSM7201 CPU does not have VFP (floating point coprocessor) and therefore floating point calculations have to be done via software-float.
This is quite disappointing as I am interested in developing applications with heavy math.
However, I also notice that the Qualcomm CPU has QDSP4000™ and QDSP5000™ high-performance digital signal processors (DSP), according to http://www.qctconnect.com/products/msm_7201.html
Therefore, here is my question: would it be possible to leverage the DSP modules in the MSM7201 CPU to do the floating point math?
Also, I would like to develop the heavy-math modules in C/C++ and call it via JNI, and so I just want to double-check whether this is a feasible approach.
Android :: Floating Point Hardware Support?
Feb 22, 2010I'm currently developing a application on a HTC Dream aka T-mobile G1. afaik the processor has a FPU coprocessor, called VFP (Vector Floating Point) in ARM terms. So far I couldn't find any information about if the FPU is used for floating point calculations or if those are emulated in software. does anyone have any information about that? the opengl implementation supports both fixed point and floating point. will my applications be slower when I'm using floating point, because they get transformed into fixed point internally? or is floating point implemented in hardware?
View 5 Replies View RelatedAndroid :: Open GL Fixed Vs Floating Point?
Jan 6, 2010OpenGL ES allows values to be specified in either fixed point or floating point format, but I haven't been able to find any information about how this is actually implemented on Android devices. Are there actually two different pipelines, one for fixed point and one for floating point? If so, what happens if you mix and match them, such as specifying your matrix in floating point but your vertices in fixed point? Alternatively, does it implement everything with just one format internally, and convert the other format to it as necessary? If so, then you presumably get the best performance if you always specify values in the internal format so as to avoid conversions. How then can I determine which format is used internally?

Jan 12, 2010I need maths for my game physics and lots of them, so I use the. Math library. And guess what? I never casted so much to floats in my entire life. And i know how costly it is to use doubles on an embedded device because I read the performance optimization page in the google android sdk docs. So I am wondering if we couldn't get a Math package with functions taking and returning floats instead of the default doubles. e.g. Math.sinf Math.cosf.

View 4 Replies View RelatedAndroid :: Floating Fixed Point For NDK OpenGL Apps?
Aug 2, 2010I'm trying to decide on whether to primarily use floats or ints for all 3D-related elements in my app (which is C++ for the most part). I understand that most ARM-based devices have no hardware floating point support, so I figure that any heavy lifting with floats would be noticeably slower. However, I'm planning to prep all data for the most part (i.e. have vertex buffers where applicable and transform using matrices that don't change a lot), so I'm just stuffing data down OpenGL's throat. Can I assume that this goes more or less straight to the GPU and will as such be reasonably fast? (Btw, the minimum requirement is OpenGL ES 2.0, so that presumably excludes older 1.x-based phones.)Also - how is the penalty when I mix and match ints and floats? Assuming that all my geometry is just pre-built float buffers, but I use ints for matrices since those do require expensive operations like matrix multiplications, how much wrath will I incur here. By the way, I know that I should keep my expectations low (sounds like even asking for floats on the CPU is asking for too much), but is there anything remotely like 128-bit VMX registers?
View 2 Replies View RelatedAndroid :: Storing Short Strings And Numeric Values In Resources
Jan 11, 2010I want to have some static numeric and text values as an application resource. For example my data is like this:
Levels 5 First_Level 500 60 1 Second_Level 500 80 1 Third_Level 200 60 1 Fourth_Level 130 30 2 Final_Level 100 30 3... and another 300 lines...
The format and order of the data is predefined and guaranteed to be valid.
I could read it with java.util.Scanner, but it's extremely slow in Android, reading a 10 KB file takes minutes. It's slow because of the regular-expression-based pattern matching inside (when I traceview'ed it).
Android :: Clicking Elements Doesn't Display Correct Values / Point Where It Would Pull Old?
Apr 14, 2010I apologize if this code looks a bit like a mess (considering the length); I figured I'd just include everything that goes on in my program at the moment.
I'm attempting to create a fairly simple Tic Tac Toe app for Android. I've set up my UI nicely so far so that there are a "grid" of TextViews. As a sort of "debug" right now, I have it so that when one clicks on a TextView, it should display the value of buttonId in a message box. Right now, it displays the correct assigned value for the first element I click, but no matter what I click afterwards, it always just displays the first value buttonID had. I attempted to debug it but couldn't exactly find a point where it would pull the old value (to the best of my knowledge, it reassigned the value).
There's a good possibility I'm missing something small, because this is my first Android project (of any note). Can someone help get different values of buttonId to appear or point out the error in my logic? The code...

Android :: How To Design A Floating Keyboard
Oct 13, 2010I am a developer and recently completed the implementation of my keyboard MessagEase. It's available on the Market (with its very- different features, making it quite unlike QWERTY).
This keyboard works fine as a replacement of the standard keyboard on an Android Phone. But for a An Android Tablet, it would work best if it's implemented as a floating, movable keyboard.
(the footprint of this keyboard is mostly dependable on the size of a human's finger; it remains the same even if the tablet's display is much larger than a phone's. Therefore it'll take a relatively smaller area on a tablet.)
If I use the current SDK hooks, it will have to take a significant portion of the screen, defeating the purpose.

View 3 Replies View RelatedAndroid :: Layout When Setting WindowIs Floating To True?
Mar 3, 2010I've got a ListActivity using the Theme.Dialog theme and windowNoTitle set to true.
Unfortunately, when I do this, the header rows (just normal rows in the list but they look like sub headers) refuse to fill_parent width (instead, they wrap_content - the header text).
I noticed this was not a problem when using the Theme theme so I started narrowing everything down to what was causing the problem.
The answer: windowIsFloating. Theme.Dialog sets this to true, and if I override this to false, then the headers happily fill the parent width.
Is there a way around this (because I would like to set windowIsFloating to true)?
