Hi,
- the struggle with the board took a lot of time - continued to investigate special loads/stores - looked for benchmarks: EEMBC Consumer filters rgbcmy and rgbyiq should be vectorizable once vld3, vst3/4 are supported EEMBC Telecom viterbi is supposed to give 4x on NEON once vectorized (according to http://www.jp.arm.com/event/pdf/forum2007/t1-5.pdf slide 29). My old version of viterbi is not vectorizable because of if-conversion problems. I'd be really happy to check the new version (it is supposed to be slightly different). Looking into other EEMBC benchmarks. FFMPEG http://www.ffmpeg.org/ (got this from Rony Nandy from User Platforms). It contains hand-vectorized code for NEON. Investigating.
I am probably taking a day off on Sunday.
