SIMDx86 will be using GNU make as a build system from here on out. Still resolving issues with it as of right now, but you can check out the SVN for the code.
SIMDx86 has finally hit its first 1000 downloads! Thank you to all who have checked out the project and it source code. If you haven't seen SIMDx86, then now it is a good time! Try reading the documentation, download the v0.4.0 tree (0.5.0 is under development), or get the bleeding 0.5.0 tree from Subversion (no seatbelts provided!)
SVN access has been enabled and will continue to be the prefered method of downloading unofficial/developmental versions of SIMDx86. The initial import contains the v0.5.0 prealpha tree, BUT IS LIKELY NOT TO COMPILE CORRECTLY AS WELL. If you are looking for stable releases, you should wait until the official release via the Sourceforge file release system.
SIMDx86 version 0.4.0 has been released. This is the last major release before the huge architectural updates that occur in 0.5.0. This release bugfixes and accelerates numerous functions. See the changelog included in the package.
There are going to be some major architectural changes in the way SIMDx86 works in version 0.4.0 -> 0.5.0.
You will still have the wonderful static link, but there is just a single unified binary. This binary contains the optimal code for ALL instruction sets/processors. At runtime, the optimal code is overlayed using VirtualProtect
() (Win32) and mprotect() (UNIX, Linux). This gives all the speed of statically linked code (no indirect function calls, i.e. function pointer or DLL/SO), and all the flexibility of a DLL/SO. This will require a massive overhaul of the existing code and some other things.... read more
The prelease of version 0.4.0 is now available. This code isn't fully accelerated by any means, but is a good sneak peak as to what to expect. There will be no binaries for 0.4.0 prerelease. Please don't use this code in production quality programs just yet!
SIMDx86 development and release of version 0.4.0 will be temporarily halted due to a two week vaction. Sorry to all who were in fact waiting for this.
Hopefully when I return, there will be Solaris 10/x86 GCC binaries available too. Hopefully.
The first release of version 0.4.0 will be soon!
All 0.3.x users should upgrade as soon as possible as this adds SSE support to the plane functions and fixes some bugs with non-SSE versions too! See the changelog for more information when it is released
Second release of libSIMDx86 v0.3! Now with better vector and matrix performance! See the changelog for full details.
That's right, the second release of version 0.3 alpha. See the full changelog at release time. Things to note:
* Improved performance for some vector functions!
* Improved performance for some matrix functions!
* Bug fix for C implementation of matrix transpose!
* Aligned functions!
* Linker error fix!
This release does not add any new functions but improves the performance of the vector functions, and some other misc. things.
* Dev-C++ project file in projects/ folder
* A few more FAQ's on main page
* SSE3 implementations of vector length functions had a useless instruction removed, as well as...
* Dot(), LengthSq(), LengthSq(), Length(), Normalize(), NormalizeOf() for SSE/SSE2/SSE3/3DNow!
This release provides for functions with Planes, Spheres, and Polygons, as well a some other minor performance updates. See the release notes at time of the release.
libSIMDx86 v0.2.1 Released! This includes very little new functionality but instead fixes bugs in the quaternion and vector libraries.
* Linux GCC 4.0.1 binaries, Win32 GCC 3.4 binaries
* Fixed bugs in SSE/SSE2/3DNow/3DNow+ code paths
* Version module
* Example C++ classes
* Compliance tests for developer debugging
The first release of SIMDx86++, the C++ classes that wrap the functionality of libSIMDx86 into a small, easy to use package. Just plug and play for instant benefit from libSIMDx86. Requires libSIMDx86 v0.2.0 or higher.
libSIMDx86 v0.2.1 Almost Complete!
This is a bugfix for v0.2 and also adds some simple version API. See the release notes when v0.2.1 is released for more information.
This release greatly extends the functionality of libSIMDx86!
*More optimized Matrix library!
*Examples for real use, including C++ class wrapper
*Build script generator (requires ANSI C compiler)
*More codepaths for SSE3 and 3DNow!+
As always, report repeatable bugs to email@example.com or on the website at http://sourceforge.net/projects/simdx86
libSIMDx86 version 0.2 is almost complete!
Features include 3D Vectors and Quaternions, plus better documentation! Stay tuned!
libSIMDx86 v0.1 released!
This release includes support for SSE/3DNow!/x87 matricies and some minor math routines such as sqrt().
Be sure to check the documentation for any questions
Work is almost complete on the matrix section using plain C, SSE, and 3DNow! instructions. A release is on the way. Feel free to comment on the message boards as you see fit.
Development has been picked up as of recently. The project was remaining undeveloped for a while, but now a new release for SSE2/SSE3 (PNI) code will be around soon!
Project started 1/26/05!
