Hello, Recently, there was a debate about using floating-point hardware for a Pixman implementation instead of the fixed point code. In our company, we have developed an FPU-based implementation of the core pixel pipeline, including support for all pixel formats and combiners, and I am now working on the resulted code to make the latter upstreamable. The patch series that follows is the first outcome of this work.
We are currently working on further improving performance characteristics of this implementation, especially in the areas where GCC is not very good in emitting good enough code for our primary architecture, namely ARM. Of course, the new implementation is being introduced in the most non-intrusive way, and is by default disabled. This way, we have yet another alternative, yet retain all current characteristics of the library. Thanks, Dmitri _______________________________________________ Pixman mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/pixman
