Initial SIMD demos life and earth for PNaCl. (Closed)
DescriptionInitial SIMD demos life and earth for PNaCl.
The Life SIMD demo exercises 16 element fixed point vectors to operate on 16
cells at a time. The Earth SIMD demo uses a mix of 4 element single precision
floating point and a small amount of fixed point SIMD. At the moment, both
demos do not exhibit much speedup from using SIMD, but this should improve as
the quality of PNaCl's code generation gets better.
Also, fix an issue where dragging a slider wasn't continuously updating in the
regular voronoi & earth demos.
